1. 1.0 x 10-14 J
2. 2.2 x 10-14 J
3. 3.6 x 10-14 J
4. 6.6 x 10-14 J

Answers

Answer 1

Photons with a frequency of 1.0 × 1020 hertz strike a metal surface. If electrons with a maximum kinetic energy of 3.0 x \(10^-^1^4^\) joule are emitted, the work function of the metal is . 3.6 x\(10^-^1^4^\) J.

The correct answer is option 3.

To determine the work function of the metal, we can use the equation:

E = hf - ϕ

where:

E is the energy of the emitted electron,

h is Planck's constant (6.626 × \(10^-^3^4\) J·s),

f is the frequency of the photons,

ϕ is the work function of the metal.

Given:

Frequency of photons (f) = 1.0 × \(10^2^0\)Hz

Maximum kinetic energy of emitted electron (E) = 3.0 × \(10^-^1^4^\) J

We can rearrange the equation to solve for the work function:

ϕ = hf - E

Substituting the given values, we have:

ϕ = (6.626 × \(10^-^3^4\) J·s)(1.0 ×\(10^2^0\) Hz) - (3.0 × \(10^-^1^4^\) J)

Simplifying the equation, we get:

ϕ = 6.626 × \(10^-^1^4^\) J - 3.0 ×\(10^-^1^4^\)J = 3.626 × \(10^-^1^4^\) J

Comparing this value to the given options, we find that the closest option is:

3. 3.6 x \(10^-^1^4^\) J

Therefore, the correct option is option 3: 3.6 x \(10^-^1^4^\)J.

This indicates that the work function of the metal, which represents the minimum energy required to remove an electron from the metal surface, is approximately 3.6 x\(10^-^1^4^\) J.

(a) assume that a neutron traveling at 3.00(103) km/s strikes the nucleus of a motionless 11na23 atom in a reactor core. the collision causes the neutron to recoil elastically, and it travels backward along exactly the same path it traveled as it approached the atom. calculate the velocity of the neutron after the collision. (b) perform the same calculation for a 3.00(103) km/s neutron striking a 3li7 atom nucleus. based on your answers from these two calculations, which metal would perform better for use as coolant in a lmfbr where high neutron velocity is preferred?

Answers

(a)  The velocity of the neutron after the collision \(3.00(10^3)\) km/s.

(b) Different materials may have different properties that make them more or less suitable as coolants in a fast breeder reactor.

(a) In an elastic collision, momentum and kinetic energy are conserved. Let m be the mass of the neutron and M be the mass of the sodium atom. Before the collision, the momentum of the neutron is

p = mv,

where v is the velocity of the neutron.

The momentum of the sodium atom is zero because it is motionless. Therefore, the total momentum before the collision is

\(p_{total} = mv\).

After the collision, the neutron recoils backward along exactly the same path it traveled, so its final momentum is

\(p_f = -mv\).

By conservation of momentum, the total momentum after the collision is also

\(p_{total} = p_f + 0 = -mv\).

Equating the total momentum before and after the collision gives:

\(p_{total} = mv = -mv\)

Solving for the final velocity \(v_f\) of the neutron, we get:

\(v_f = -v = -3.00(10^3)\) km/s

Therefore, the velocity of the neutron after the collision is \(3.00(10^3)\) km/s in the opposite direction.

(b) We follow the same procedure as in part (a), but with a lithium atom instead of a sodium atom.

Let M be the mass of the lithium atom.

Before the collision, the momentum of the neutron is

p = mv,

where v is the velocity of the neutron.

The momentum of the lithium atom is zero because it is motionless. Therefore, the total momentum before the collision is

\(p_{total} = mv\)

After the collision, the neutron recoils backward along exactly the same path it traveled, so its final momentum is

\(p_f = -mv\).

By conservation of momentum, the total momentum after the collision is also \(p_{total} = p_f + 0 = -mv\).

Equating the total momentum before and after the collision gives:

\(p_{total} = mv = -mv\)

Solving for the final velocity \(v_f\) of the neutron, we get:

\(v_f = -v = -3.00(10^3)\) km/s

Therefore, the velocity of the neutron after the collision is \(3.00(10^3)\) km/s in the opposite direction.

Comparing the results of parts (a) and (b), we see that the type of metal does not affect the velocity of the neutron after an elastic collision. However, different materials may have different properties that make them more or less suitable as coolants in a fast breeder reactor.

f the large ring, small ring, and each of the spokes weigh 100 lb, 15 lb, and 20 lb, respectively. what is the mass moment of inertia of the wheel about an axis perpendicular to the page and passing through point a?

Answers

The mass moment of inertia of the wheel about an axis perpendicular to the page and passing through point A can be calculated by summing the contributions from the large ring, small ring, and each of the spokes.

The total mass moment of inertia depends on the mass distribution and the distances of the respective components from the axis of rotation. The mass moment of inertia (I) is a measure of an object's resistance to changes in rotational motion. For a composite object like the wheel in question, the mass moment of inertia can be calculated by summing the individual contributions. Each component's mass moment of inertia (I_comp) is given by the formula I_comp = m_comp * r_comp^2, where m_comp is the mass of the component and r_comp is its perpendicular distance from the axis of rotation.

In this case, we would calculate the mass moment of inertia of the large ring, small ring, and each spoke separately using their respective masses and distances from point A. Then, we would sum these individual values to obtain the total mass moment of inertia of the wheel about the given axis.

Self-ignition would occur in the engine uing certain brand of petrol if the temperature due to
compreion reached 350°C. Calculate the highet ratio of compreion that may be ued to avoid pre-ignition if the law of
compreion i

Answers

Self-ignition, also known as pre-ignition, occurs in an internal combustion engine when the fuel-air mixture in the combustion chamber ignites before the spark plug fires.

One way to avoid pre-ignition is to limit the compression ratio of the engine, as a higher compression ratio can lead to higher temperatures in the combustion chamber.

The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

The compression ratio of an engine is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke (the "swept volume") to the volume of the combustion chamber when the piston is at the top of its stroke (the "clearance volume").

Given that the temperature at which self-ignition would occur using a certain brand of petrol is 350°C, and assuming that the ideal gas law applies, we can calculate the highest compression ratio that may be used to avoid pre-ignition.

To do this, we need to know the initial temperature and pressure in the combustion chamber, as well as the final temperature and pressure after compression. We can then use the ideal gas law to calculate the compression ratio.

In conclusion, based on the information provided, it is possible to calculate the highest compression ratio that may be used to avoid pre-ignition in an engine using the ideal gas law. However, more specific information such as the initial temperature and pressure and the specific brand of petrol is needed for a more accurate calculation.

Based on this experiment and the collected data, what would their conclusion be?
A) Gravitational attraction is dependent on the mass of an object.
B) The greater the mass of the object the greater the acceleration due to gravity and the faster it will fall.
C) Mass does not affect the speed of falling objects assuming there is only the force of gravity acting on the objects.
D) Mass becomes a factor affecting the speed of a falling object when the object is dropped a great distance from the surface of the Earth.

Answers

Answer:B

Explanation:

The force of gravitation depends on the mass of the object. As the mass increases, the speed of the falling object also increases because it experience more gravitational pull from earth. Thus, option D is correct.

What is gravitational force?

Gravitational force is a kind of force by which an object attracts other objects into its center of mass. We are all standing on the ground because of the gravitational pull of earth.

Gravitational force is directly proportional to the mass of the objects and inversely proportional to the distance from the surface. Therefore, the force exerted by earth on massive body is greater than that on a light body.

Here, the ball with greater  mass hit the ground with less time compared to the one with less mass. Hence, the mass becomes a factor  affecting the speed of a falling object when the object is dropped a great distance from the surface of the earth. Thus, the massive body will be pulled more by earth.

The statement exists true. Alternating current (AC) frequently changes its direction, while direct current (DC) only moves in one direction and cannot do so.

What is the difference between direct current and alternating current?

When compared to direct current (DC), which only travels in one direction and cannot sporadically shift, alternating current (AC) is an electric current that periodically flips direction.

Alternating current (AC) frequently changes its direction, while direct current (DC) only moves in one direction and cannot do so.

An electrical circuit is a non-stop, continuous loop constructed of conductive material that enables electrons to travel through it without starting or stopping.

Direct current is formed when electrons move continuously in one direction. To identify it, use "DC". Due to the fact that direct current can only flow in one direction, its electrical pressure or voltage is always oriented in that direction, or "polarity."

The engine of a boat (m = 1580 kg) exerts a
2200 N force northward, while the current
pushes it 1350 N eastward.
In what direction does the boat accelerate?

Answers

Answer:

58.5

Explanation: no clue on how to do it but i just got that answer on my accelus✨

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. The direction of the boat is northward and its magnitude is 1.633 m/s².

What is acceleration?

An object is said to be accelerated if there is a change in its velocity. The rate of change of velocity with respect to time is known as the velocity. It is a vector quantity and it has both magnitude and direction. It is the first derivative of velocity with respect to time.

Fx = 2200 [N]

Fa = 1350 [N]

F = √(Fₓ)² + (Fₐ)²

F = √(2200)² + (1350)²

F = 2581.18 N

Now using Newton's second law.

F = m×a

a = F / m

a = 2581.18 / 1580

a = 1.633 m/s²

Thus acceleration is 1.633 m/s² and it is northward direction.

In order to calculate a planet's orbital period, we must know the dimensions of its orbit. The correct answer is C.

To calculate a planet's orbital period, we need to know the dimensions of its orbit, specifically the semi-major axis. The semi-major axis is the average distance between the planet and its parent star (assuming a circular or nearly circular orbit). The orbital period of a planet is determined by its distance from the star and the mass of the star.

The tilt of the planet's axis (option A) affects the planet's seasons but does not directly impact its orbital period. The radius of the planet (option B) is not directly related to its orbital period either.

How much energy is converted into heat when the cart is at the base level of the track? Show your work.

Answers

The amount of energy converted into heat when the cart is at the base level of the track is approximately 7490 J.

What is kinetic energy?

The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it.

Kinetic energy:

E = mgh

E = (958 kg) x (9.81 m/\(s^2\)) x (55 m) = 5.26 x \(10^5\) J

E = KE + Q

KE is the kinetic energy of the cart and Q is the energy converted into heat. Substituting the given value for the kinetic energy, we get:

5.26 x \(10^5\) J = 511,000 J + Q

Solving for Q, we get:

Q = 5.26 x \(10^5\) J - 511,000 J = 7490 J

Thus, 7490 J energy is converted into heat.

________ was the first astronomer to track sunspot movement with the aid of a telescope.

Answers

Galileo Galilei was the first astronomer to track sunspot movement with the aid of a telescope. His observations played a significant role in the development of our understanding of the Sun.

Galileo, an Italian astronomer and physicist, made his groundbreaking sunspot observations in 1610-1613. Using the newly invented telescope, he was able to see that the Sun had spots on its surface that appeared to move over time. Prior to Galileo's discovery, the prevailing belief was that the Sun was a perfect, unblemished sphere. His observations challenged this notion and contributed to a broader shift in our understanding of the cosmos.

Galileo's work on sunspots not only provided evidence of the Sun's imperfect surface but also demonstrated that the spots were connected to the Sun and not separate objects, as some had previously thought. By observing the movement of sunspots, Galileo was able to determine that the Sun rotates on its axis, further solidifying the idea that celestial bodies were not static and unchanging.

In summary, Galileo Galilei's groundbreaking observations of sunspots with the aid of a telescope marked a turning point in our understanding of the Sun and the broader universe. His work challenged the existing beliefs of his time and paved the way for future astronomers to further explore and understand our solar system.

The entropy of the universe increases for spontaneous processes is increases.

The entropy of the universe increases for spontaneous processes. The entropy of the universe is constantly increasing because all processes that occur spontaneously increase the entropy of the universe. Entropy, in simple terms, is the amount of disorder or randomness in a system. When a spontaneous process occurs, it results in an increase in the disorder of the system, and therefore, an increase in entropy.

Entropy, in thermodynamics, is the measure of randomness or disorder in a system. Entropy is a thermodynamic function that is closely related to the concept of the probability of a system or a state. The entropy of a system is given by the second law of thermodynamics, which states that the total entropy of a system and its surroundings always increases for any spontaneous process. In other words, all spontaneous processes increase the entropy of the universe. Spontaneous processes are those that occur naturally and do not require any external energy or work to be performed. Some examples of spontaneous processes include the diffusion of gas molecules from a high concentration to a low concentration, the melting of ice, and the rusting of iron. All these processes result in an increase in the disorder of the system and an increase in entropy.

Therefore, the correct answer to the question is “a. increases” because the entropy of the universe increases for spontaneous processes. This is due to the second law of thermodynamics, which states that the total entropy of a system and its surroundings always increases for any spontaneous process.
