A 2.0 kg sponge is dropped from rest, pulled down by gravity. How fast will it be travelling in 6.0 s, if a 5.0 N force of air Resistance acts on it?

A maciromwave and an X-ray are traveling in a vacuum compared to the wavelnegth and period of the microwave,  the X-ray has a wavelnegth that is shorter than that of a microwave

A microwave and an X-ray are both electromagnetic waves that travel through a vacuum, they differ in their wavelength and frequency. The wavelength of an X-ray is shorter than that of a microwave. The wavelength and period of a wave are inversely proportional. This means that as the wavelength decreases, the frequency and period increase. This is the case for X-rays, which have a high frequency and short period compared to microwaves.

In terms of energy, X-rays have more energy than microwaves due to their shorter wavelength. This allows X-rays to penetrate materials more easily and be used in medical imaging. In conclusion, the wavelength and period of a wave are inversely related. X-rays have a shorter wavelength and higher frequency compared to microwaves, allowing them to have more energy and penetrate materials more easily. So therefore the wavelength of an X-ray is shorter than that of a microwave.

Explanation:

v = Velocity of the elevator = 3.1 m/s

\(\theta\) = Angle of the slope = \(30^{\circ}\)

Vertical component is given by

\(v_y=v\sin\theta\\\Rightarrow v_y=3.1\sin30^{\circ}\\\Rightarrow v_y=1.55\ \text{m/s}\)

The vertical component of the velocity is \(1.55\ \text{m/s}\).

Horizontal component is given by

\(v_x=v\cos\theta\\\Rightarrow v_x=3.1\times \cos30^{\circ}\\\Rightarrow v_x=2.68\ \text{m/s}\)

The horizontal component of the velocity is \(2.68\ \text{m/s}\).

What is Veto Power?

Veto power is the power of an individual or group to reject a decision or proposal made by others. In a political context, veto power is often held by the executive branch of government, such as a president or a governor, who can veto a bill passed by the legislative branch, such as a parliament or a congress. By vetoing a bill, the executive can prevent it from becoming law, unless the veto is overridden by a supermajority of the legislative branch.

If the bill is passed by both the Senate and the House of Representatives, it is then sent to the President for signature. If the President vetoes the bill, Congress can override the veto with a two-thirds vote in both the House and Senate. Once a bill has been enacted, it becomes a law and is part of the United States Code.

It can be one element by itself.

Explanation:

The density of O2 at cruising altitude, relative to sea-level, is approximately 0.379 times the density at sea-level.

The density of O2 at cruising altitude of 36,000ft, relative to sea-level, can be calculated using the relationship between pressure and altitude. At higher altitudes, the pressure decreases, which affects the density of gases.

To find the density of O2 at cruising altitude, we can compare the pressure at that height to the pressure at sea-level. The pressure decreases with altitude, so we need to determine the ratio of the pressures.

Assuming the temperature does not differ with increased altitude, we can use the ideal gas law equation:

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.

At sea-level, the pressure is around 1 atmosphere (atm). At cruising altitude, the pressure is lower. The relationship between pressure and altitude can be approximated using the barometric formula:

\(P = P0\cdot e^(-h/H)\)

where P0 is the pressure at sea-level, e is the base of the natural logarithm, h is the altitude, and H is the scale height.

In this case, we can substitute the given values: P0 = 1 atm, h = 36,000ft, and H = 8,400ft (approximately).

Using the barometric formula, we can calculate the pressure at cruising altitude:

\(P = 1 atm \cdot e^(-36,000ft/8,400ft)\)

P ≈ 0.379 atm

Now, to find the density of O2 at cruising altitude relative to sea-level, we can use the ideal gas law. The number of moles remains constant, so we can compare the densities using the ratio of the pressures:

Density at cruising altitude / Density at sea-level = Pressure at cruising altitude / Pressure at sea-level

Density at cruising altitude / Density at sea-level = 0.379 atm / 1 atm

Density at cruising altitude / Density at sea-level ≈ 0.379

Therefore, the density of O2 at cruising altitude, relative to sea-level, is approximately 0.379 times the density at sea-level.

The velocity is defined as the rate of change of displacement per unit time and the unit of velocity is m/s. Velocity is of two types and they are average velocity and instantaneous velocity.

A) From the given graph, object B traveled faster when compared with object A. Because the speed of object B increases gradually with time whereas the speed of object A decreases with time. Hence, object B travels faster.

B)The velocity increases with time 2s to 4s. The velocity is defined as the rate of change displacement by time taken. v = Δx/Δt, where Δx is the change in displacement and Δt is the time taken. Δx = final.dis - initial dis = 0-(-4) = 0+4 = 4 m. Δt = final.time-ini.time = 4-2 = 2s. Thus, the velocity v = 4/2 = 2 m/s. Hence, the velocity increases gradually.

C) The acceleration is defined as the rate of change of velocity per unit time. From the given graph, the change in velocity does not change, and hence Δv = 0. Acceleration a = Δv/Δt = 0. Thus, the acceleration of the object is zero.

D) Acceleration (a) is the rate of velocity per unit time and the unit of velocity is m/s². Acceleration (a) = Δv/Δt, where Δv is the change in velocity. Δv = final.velocity - initial.velocity = 8-(-2) = 8+2 = 10 m/s. Δt = final. time-initial. time = 7-3 = 4s. a = 10/4=2.5m/s². Hence, the acceleration is 2.5m/s².

E) Force is the product of mass and acceleration. From the given, the force moves in both forward and backward directions, and hence, force is a vector quantity. F(net) = F₁+F₂=18 - 6 = 12N. The mass of the cart is 2kg.

There are a many ways to produce electricity. Electrons can flow between certain different materials providing a current, as in a common battery. While reliable and portable, chemical batteries run down quickly. To provide the large amounts of steady power demanded by modern societies, large power plants have been built. Most power plants make electricity with a machine called a generator.

A 1925 Turbine Rotor

A 1925 turbine rotor for a Westinghouse generator, Image #21.035, Science Service Historical Image Collection, National Museum of American History

Generators have two important parts: the rotor (which rotates) and the stator (which remains stationary). Generators use the principle of electro-magnetic induction, which exploits the relation between magnetism and electricity. In large AC generators, an outer shell with powerful magnets rotates around a stationary "armature" which is wound with heavy wire. As they move, the magnets induce an electric current in the wire.

It is important to recognize that electricity is not mined or harvested, it must be manufactured. And since it's not easily stored in quantity, it must be manufactured at time of demand. Electricity is a form of energy, but not an energy source. Different generating plants harness different energy sources to make electric power.

Let's designate v for vertical velocity and u for horizontal velocity.

Say the horizontal distance (R) is equal to the horizontal velocity (u) times the flying duration (t). In mathematics, R = u T.

But first, we need a flight time (t). Utilizing the equation of motion, which is

v1=v0+at

In this case, v0=20,v1=0,a=g=9.81m/s2, negative because the projectile decelerates as it goes upward. From this point, the projectile's maximum height(t) calculation yields a time of 2.04 seconds.

The baseball will reach its maximum height after approximately 6.11 seconds using equations of motion where velocity is given

When a baseball is thrown straight up with an initial velocity of 60 m/s, it will eventually reach a maximum height before falling back down due to gravity. To determine how many seconds later the baseball will reach its maximum height, we need to use the equations of motion.

The equation we can use to find the time taken for the baseball to reach its maximum height is:

t = Vf / g

where t is the time taken, Vf is the final velocity (which is zero at the maximum height), and g is the acceleration due to gravity, which is approximately \(9.81 m/s^2\).

Substituting:

t = 60 / 9.81

t ≈ 6.11 seconds

Therefore, the baseball will reach its maximum height after approximately 6.11 seconds. After this point, the baseball will begin to fall back down to the ground due to the force of gravity, with its velocity increasing at a rate of \(9.81 m/s^2\)

Explanation:

Given the following data;

Mass = 250 g to kilograms = 250/1000 = 0.25 kg

Acceleration = 50 m/s²

To find the force;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

\( Acceleration = \frac {Net \; force}{mass} \)

Making force the subject of formula, we have;

\( Force = mass * acceleration \)

Substituting into the formula, we have

\( Force = 0.25 * 50 \)

Force = 12.5 Newton
