Answer:

to the substance being heated

Answer:

Explanation:

Condensing is the word used to indicate the change of state of a substance from vapor to liquid, as in this case. During condensation, the substance releases thermal energy to the environment, therefore the kinetic energy of the molecules in the vapor decreases until they become closer to each other and they start to be affected by the intermolecular forces and so the substance becomes a liquid.

The monochromatic laser light passing through two small slits with large spacing produces a bright fringe at the midpoint on a distant screen due to constructive interference, which occurs when the light from one slit travels exactly one wavelength farther than the light from the other slit, and both light waves reach the midpoint in phase.

The phenomenon described in your question is known as interference. When a laser beam passes through two small slits that are very close to each other, the light waves interfere with each other and create a pattern of bright and dark fringes on a distant screen. The bright fringe that is centered at the midpoint is caused by constructive interference, where the crests of the waves from one slit coincide with the crests of the waves from the other slit. This occurs because the distance traveled by the light from one slit to the midpoint is exactly one wavelength longer than the distance traveled by the light from the other slit.
It's important to note that for this phenomenon to occur, the slit spacing must be large compared to the distance to the screen, and the laser light must be monochromatic (meaning it contains only one wavelength). Additionally, the light waves must travel the same distance from each slit to the midpoint. These conditions are necessary for the waves to interfere constructively and create a visible interference pattern on the screen.

A) The period (T) will be approximately 2.6 s if the mass is doubled.

b) The period (T) will be approximately 1.3 s if the mass is halved.

c) The period (T) remains unchanged if the amplitude is doubled.

d) The period (T) remains unchanged if the spring constant is doubled.

For a mass-spring system undergoing simple harmonic motion, the period of oscillation is given by the formula:

T = 2π * √(m/k)

where T is the period, m is the mass of the block, and k is the spring constant.

Part A:Period (T) = 1.8 s, Mass (m) = 2m (doubled)

Using the formula:

T = 2π * √(m/k)

Substituting the given values:

1.8 = 2π * √(2m/k)

Solving for T:

1.8 / (2π) = √(2m/k)

Square both sides:

(1.8 / (2π))² = 2m/k

Simplifying:

(1.8²) / (4π²) = 2m/k

Solving for T:

T = (1.8² * k) / (4π² * 2m)

Calculating:

T ≈ (3.24 * k) / (12.57 * m)

Part B:

Period (T) = 1.8 s

Mass (m) = 0.5m (halved)

Using the formula:

T = 2π * √(m/k)

Substituting the given values:

1.8 = 2π * √(0.5m/k)

Solving for T:

1.8 / (2π) = √(0.5m/k)

Square both sides:

(1.8 / (2π))² = 0.5m/k

Simplifying:

(1.8²) / (4π²) = 0.5m/k

Solving for T:

T = (0.9² * k) / (4π² * 0.5m)

Calculating:

T ≈ (0.81 * k) / (12.57 * m)

In Part C, the period remains unchanged because the period of oscillation in simple harmonic motion is only dependent on the mass and spring constant, not the amplitude.

In Part D, the period also remains unchanged because the period of oscillation is independent of the spring constant.

Answer: \(0.708\ mA\)

Explanation:

Given

\(E_o=20\ V/m\)

\(\omega =10^7\ s^{-1}\)

Cross-sectional area \(A=0.40\ m^2\)

Current density is given by

\(J=\epsilon_o \dfrac{dE}{dt}\)

Displacement current

\(\Rightarrow I=JA\\\Rightarrow I=8.854\times 10^{-12}\times 20\times 10^7\times 0.4\\\Rightarrow I=0.708\times 10^{-3}\ A\)

The required value of the maximum displacement current of the given space is  \(7.08 \times 10^{-4} \;\rm A\).

Given data:

The intensity of electric field is, \(E_{0}=20 \;\rm V/m\).

The angular frequency of electric field is, \(\omega=1.0 \times 10^{7} \;\rm s^{-1}\).

The cross-sectional area of space is, \(A =0.40 \;\rm m^{2}\).

In the given problem, the instantaneous electric field is given by \(E = E_{0} \times cos(\omega t)\)

So, the expression for the current density is,

\(J= \epsilon_{0} \times \dfrac{dE}{dt}\)

Here, \(\epsilon_{0}\)  is the permittivity of free space. Solving as,

\(J= \epsilon_{0} \times \dfrac{d(E_{0} \times cos(\omega t))}{dt}\\\\J= -\epsilon_{0} \times E_{0} \times \omega \times sin(\omega t)\)

And the expression for the maximum displacement current is,

\(I = J \times A\)

And the maximum displacement current is possible only when, J is positive and J will be positive for  \(sin(\omega t)=-1\).

Then solving as,

\(I = (-\epsilon_{0} \times E_{0} \times \omega \times sin(\omega t)) \times A\\\\I = (-8.85 \times 10^{-12} \times 20 \times (1.0 \times 10^{7}) \times (-1)) \times 0.40\\\\I = 7.08 \times 10^{-4} \;\rm A\)

1. Unpolarized light is made up of of light waves vibrating in all possible directions perpendicular to the path of propagation.

2. The analyzer is a second type of filter.  

Plane-polarized light is a type of light wave in which the electric field vibrations are constrained to a single plane.

This means that the electric field vectors of the light wave all vibrate in the same direction, perpendicular to the direction of propagation of the light wave.

Plane-polarized light can be created by passing unpolarized light through a polarizer. A polarizer is a material that allows only light waves with electric field vibrations parallel to a certain direction to pass through.

When plane-polarized light passes through an analyzer whose transmission axis is perpendicular to the transmission axis of the polarizer, all of the light is blocked.

This is because the electric field vibrations of the plane-polarized light are no longer parallel to the transmission axis of the analyzer. This is why when you have crossed polars, you see a black background.

The value of the smaller resistance (R₁) of the two resistances is 24 Ω.

To solve this problem, let's denote the unknown resistances as R₁ and R₂, with R₁ being the smaller resistance. We'll use the principle of the meter bridge to determine their values.

In the balanced condition, the ratio of the resistances is given by:

R₁/R₂ = l1/l2

Where l1 and l2 are the lengths of the bridge wire on the left and right sides of the null point, respectively.

Given:

Length of the meter bridge wire = 100 cm

Null point position without the 30 Ω resistor = 40 cm

Null point position with the 30 Ω resistor = 80 cm (shifted by 20 cm)

Using the above equation for both cases, we have:

R₁/R₂ = l1/l2   ... (Equation 1)

(R₁ + 30)/R₂ = (100 - l1)/(100 - l2)   ... (Equation 2)

Substituting the given values, we get:

R₁/R₂ = 40/60   ... (Equation 3)

(R₁ + 30)/R₂ = 60/40   ... (Equation 4)

Simplifying Equation 3 and Equation 4, we have:

R₁/R₂ = 2/3   ... (Equation 5)

(R₁ + 30)/R₂ = 3/2   ... (Equation 6)

From Equation 5, we can write:

R₁ = (2/3)R₂   ... (Equation 7)

Substituting Equation 7 into Equation 6, we get:

(2/3)R₂ + 30 = (3/2)R₂

Multiplying both sides by 6 to eliminate fractions:

4R₂ + 180 = 9R₂

5R₂ = 180

R₂ = 36 Ω

Substituting R₂ = 36 Ω into Equation 7, we can find R₁:

R₁ = (2/3)R₂

R₁ = (2/3)(36 Ω)

R₁ = 24 Ω

Therefore, the value of the smaller resistance (R₁) is 24 Ω.

You were approximately 5.72 meters away from the second baseman. The vertical drop or distance between point A and point B was approximately 0.4576 meters.

To determine the distance between you (the shortstop) and the second baseman, we can use the formula for horizontal distance (d) traveled by an object moving at a constant horizontal velocity:

d = v * t

where:

- d is the horizontal distance traveled,

- v is the horizontal velocity of the ball,

- t is the time taken.

Given that the horizontal velocity (v) is 13 m/s and the time (t) is 0.44 s, we can calculate the horizontal distance (d) as follows:

d = 13 m/s * 0.44 s = 5.72 meters

So, you were approximately 5.72 meters away from the second baseman.

To find the vertical drop or the distance between point A and point B, we need to calculate the vertical component of the ball's motion. Since the ball is thrown horizontally, it will experience a constant vertical acceleration due to gravity.

The formula to calculate the distance (d) traveled vertically in free fall is:

d = 1/2 * g * t²

where:

- d is the vertical distance traveled,

- g is the acceleration due to gravity (approximately 9.8 m/s²),

- t is the time taken.

Given that the time (t) is 0.44 s, we can calculate the vertical distance (d) as follows:

d = 1/2 * 9.8 m/s² * (0.44 s)² = 0.4576 meters

The runner is approximately 8.98 km away from her starting point.

To find the distance of the runner from her starting point, we can use the concept of vector addition and trigonometry.

Let's break down the runner's movement into two components:

Eastward component: The runner initially runs due east for 6 km. Since this is in the eastward direction, the magnitude of this component is 6 km in the positive x-direction.

Northward component: After changing course to E25°N, the runner runs another 9 km. This can be broken down into two components: northward and eastward.

Using trigonometry, we can determine the magnitudes of these components:

The northward component is given by 9 km * sin(25°).

The eastward component is given by 9 km * cos(25°).

Now, let's calculate the magnitudes of the components:

Northward component = 9 km * sin(25°) ≈ 3.80 km

Eastward component = 9 km * cos(25°) ≈ 8.13 km

To find the total displacement from the starting point, we can add the magnitudes of the components using vector addition. This can be visualized as creating a right-angled triangle, with the eastward and northward components as the two sides.

Applying the Pythagorean theorem, the total displacement (d) is given by:

d = √((eastward component)^2 + (northward component)^2)

=\(\sqrt{(8.13 km)^2 + (3.80 km)^2}\))

≈ \(\sqrt{(66.16 km^2 + 14.44 km^2}\))

≈ \(\sqrt{80.6 km^2}\)

≈ 8.98 km

It is more difficult to stop a sled carrying 2 people on than to stop a sled carrying 1 person if both have the same velocity because the sled carrying 2 people has more mass.

The greater the mass of an object, the greater the force required to change its velocity or stop it entirely.

What is the difference between mass and velocity? The difference between mass and velocity is as follows:

Mass is the amount of matter that an object possesses, whereas velocity is the rate at which an object changes position over time. Mass is a scalar quantity that represents an object's resistance to changes in motion, whereas velocity is a vector quantity that represents the rate and direction of motion.

Difficulty in stopping a sled with two persons. The sled with two people has more mass than the sled with one person. It is therefore more difficult to stop. When a sled is sliding on the snow, the force of friction between the sled's runners and the snow is what keeps it from slipping uncontrollably.

As the force of friction opposes the sled's motion, it generates a force that opposes the sled's forward movement. When there are two people on the sled, there is more mass and therefore more resistance to the opposing force created by the friction. Therefore, it is more difficult to stop a sled carrying two people than to stop a sled carrying one person.
