The wavelength of the second light is 6.5 x 10⁻⁶.

The wavelength of the third light is 4 x 10⁻⁶.

Grating constant, d = 5 x 10⁻⁵m

An optical element having a periodic structure that divides light into several beams that move in different directions is known as a diffraction grating.

It is an alternate method of using a prism to view spectra. Typically, the divided light will have a maximum at an angle when light is incident on the grating.

The expression for the diffraction grating is given by,

nλ = d sinθ

1) sinθ = 10 x 10⁻²/1 = 10⁻¹

So, the wavelength of the light is,

λ = d sinθ

λ = 5 x 10⁻⁵ x 10⁻¹

λ = 5 x 10⁻⁶m

2) sinθ = 13 x 10⁻²/1 = 1.3 x 10⁻¹

So, the wavelength of the light is,

λ = d sinθ

λ = 5 x 10⁻⁵x 1.3 x 10⁻¹

λ = 6.5 x 10⁻⁶m

3) sinθ = 8 x 10⁻²/1 = 8 x 10⁻²

The negative sign means deceleration, which shows that the limousine was slowing down to stop.

Explanation:

The formula for acceleration is :

a= change in velocity / time

\(a=v_f-v_i/t\\\)

where;

\(v_f=0km/h\\\\v_i=55km/h\\\\t=4.352s\)

a= 0-55 /4.352 = -55/4.352 = -12.64 m/s²

The negative sign means deceleration, which shows that the limousine was slowing down to stop.

When a distant star is traveling directly away from Earth with a speed of 38500 km/s, the wavelengths in the star's spectrum as measured on Earth would be greater than the wavelengths we would observe if the star were at rest relative to us. This effect is known as the redshift.

The redshift occurs because the motion of the star causes a Doppler shift in the wavelengths of light emitted by the star. The Doppler effect causes the wavelengths of light to stretch out (i.e., increase in wavelength) if the source is moving away from the observer. The amount of stretching or redshift is proportional to the velocity of the star relative to the observer and the wavelength of the light.

In this case, the star is moving away from Earth at a high velocity of 38500 km/s, so the wavelengths of light that we observe on Earth will be stretched out or increased compared to the wavelengths emitted by the star when it was at rest. This means that the wavelengths in the star's spectrum will be greater (i.e., shifted towards the red end of the spectrum) than the wavelengths we would observe if the star were at rest relative to us.

If an early frost destroys most of the apple crop, the equilibrium price of an apple is likely to increase.

An early frost that damages a significant portion of the apple crop would result in a decrease in the supply of apples. When the supply decreases, while demand remains constant or even increases, it creates a situation where the quantity demanded exceeds the quantity supplied. This imbalance in the market typically leads to an increase in the equilibrium price of apples.

With a reduced supply of apples, consumers would still desire to purchase them at the same or even higher quantities, especially if there are no close substitutes available. As a result, buyers may be willing to pay a higher price to secure the limited supply of apples. This increased demand coupled with the decreased supply causes the equilibrium price to rise.

Moreover, the extent of the increase in price will depend on the severity of the frost damage and the elasticity of demand. If the damage is severe and there are no alternative sources of apples, the price increase may be significant. However, if there are other regions or countries with unaffected apple crops that can fulfill the demand, the price increase may be relatively moderate.

The ideal gas law allows us to relate the pressure, volume, and temperature of an ideal gas. We can use the equation pv=nrt, where r is equal to 8.314 47 j/k mol in order to determine the pressure of an ideal gas given the number of moles, volume, and temperature.

In this case, we have 0.600 mol of a gas occupying 0.007 10 m3 at a temperature of 315.0 k. By plugging these values into the equation, we can solve for the pressure, which is 4.1340 x 105 Pa, stated to the appropriate number of significant digits.

The ideal gas law is an incredibly useful equation that can be used to calculate the pressure, volume, and temperature of an ideal gas given the values of two of the three. The ideal gas law is based on the kinetic-molecular theory which states that all particles of a gas are in constant motion and that the pressure of the gas is a result of the force of the particles on the walls of the container.

Answer:

The person above is correct, The Answer is "CONTRATION" just verified it by ap.ex ;)

Explanation:

The force applied at the height of h on the cabinet with dimensions w and l and mass m, mounted on locked casters sliding on a rough floor with a kinetic coefficient of friction μk, will result in a certain amount of horizontal displacement.

When a force F is applied at height h on the cabinet, it creates a torque (moment) around the bottom edge of the cabinet. This torque causes a rotational force on the cabinet, trying to rotate it. However, since the casters are locked, the cabinet cannot rotate and instead experiences a linear motion.

The force F generates a downward component Fcosθ and a horizontal component Fsinθ, where θ is the angle between the applied force and the vertical axis. The downward component contributes to the normal force between the cabinet and the floor, while the horizontal component generates a frictional force opposing the motion.

The frictional force can be calculated using the formula Ffriction = μk * N, where N is the normal force. The normal force is equal to the weight of the cabinet, which is m * g, where g is the acceleration due to gravity. Thus, the frictional force is Ffriction = μk * m * g.

The net force acting on the cabinet horizontally is the difference between the applied force Fsinθ and the frictional force. Therefore, the net force is Fnet = Fsinθ - μk * m * g. This net force causes the cabinet to accelerate horizontally.

To determine the resulting displacement, we can use Newton's second law, which states that Fnet = m * a, where a is the acceleration. Rearranging the equation, we find that the acceleration a = Fnet / m.

Once we have the acceleration, we can use the equations of motion to calculate the displacement. The specific equation will depend on the initial conditions, such as the initial velocity of the cabinet or the time over which the force is applied.

Answer:

0.67 ms

Explanation:

The total time it takes the sound to enter and leave the water is t and

t = t' + t" where t' = total time of sound in air = d'/v' where d' = total distance sound travels in water = 2D (since the sound waves passes through the water twice )where D = distance travelled from water to surface of copper block = 0.45 m and v' = speed of sound in water = 1500 m/s and  t" = total time of sound in copper = d"/v" where d" = total distance sound travels in copper block = 2D' (since the sound waves passes through the copper block twice )where D' = thickness of copper block = 0.15 m and v" = speed of sound in water = 4600 m/s

So, t = t' + t"

t = d'/v' + d"/v"

t = 2D/v' + 2D'/v"

Substituting the values of the variables into the equation, we have

t = 2 × 0.45 m/1500 m/s + 2 × 0.15 m/4600 m/s

t = 0.90 m/1500 m/s + 0.30 m/4600 m/s

t = 0.0006 s + 0.000065 s

t = 0.000665 s

t = 0.665 ms

t ≅ 0.67 ms

Note that the sound wave passes through the water and copper block without refracting since it enters perpendicularly. Also, the sound wave passes twice through each of the copper block and water hence the total distance in each material is twice the initial distance or thickness.

Answer:

    t = 6.63 10⁻⁴ s

Explanation:

The speed of sound is constant in a given material medium, so to calculate time we can use the uniform motion relationships

           v = d / t

           t = d / v

the speeds of sound in the three media are

air            v = 343 m / s

water       v₁ = 1493 m / s

copper    v₂ = 5010 m / s

the distance traveled in the water on the round trip is

             d = 2 x

             d₁ = 2 0.45 0.90m

the time to travel this distance is

             t₁ = d₁ / v₁

             t₁ = 0.9 / 1493

             t₁ = 6.028 10⁻⁴ s

the distance in the copper

             d₂ = 2 0.15 m

             d₂ = 0.30 m

the time to travel this distance in copper is

              t₂ = d₂/ v₂

              t₂ = 0.30 / 5010

              t₂ = 5.988 10⁻⁵-5 s

the total travel time is

             t = t₁ + t₂

             t = 6.028 10⁻⁴ + 0.5988 10⁻⁴

             t = 6.6268 10⁻⁴ s

             t = 6.63 10⁻⁴ s

The mass and weight of object on moon is 0.0138kg  and 0.0229kg .

Since force is a vector quantity, we must consider the direction in which it acts. There are two main types of frictional force: static force (Fst) and sliding force (Fsl). Normal forces (FN) produce these forces acting perpendicular to the direction of motion, although they act in the opposite direction to the object's motion.

It is equivalent to the weight of the object plus the extra weight. For example, pushing down on a block of wood on a table increases the normal force and thus the frictional force.

me=12Kg
