If you change the source of wavelength to a longer wavelength (e.g. 600 nm), the distance between the zero order maximum and the third order maximum will decrease, since the numerator (λ) has increased.

The distance between the zero order maximum and the third order maximum in a diffraction pattern depends on the wavelength of the light and the size of the diffraction grating.

If you change the source wavelength from a shorter wavelength to a longer wavelength, the distance between the zero order maximum and the third order maximum will decrease. This is because the distance between the maxima in a diffraction pattern is inversely proportional to the wavelength of the light.

In mathematical terms, if 'd' is the distance between the maxima, 'λ' is the wavelength, and 'n' is the order of the maximum, then the relationship between these quantities is given by:

d = λ / (n × sinθ)

The ball that was dropped from a height of 2 meters will hit the ground first. This is because the ball that was dropped was not given any horizontal velocity, so it will fall straight down with an acceleration of 9.8 m/s2.

Velocity is a vector quantity that describes the rate and direction of an object's motion. It is defined as the rate of change of an object's position, with respect to time. Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is usually expressed in meters per second (m/s), but it can also be expressed in other units such as kilometers per hour (km/h).

The ball that was hit with a horizontal velocity of 20 m/s will travel horizontally for a certain amount of time before it begins to fall and accelerate downwards. As a result, the ball that was dropped will hit the ground first.

a) The package takes 2.45 seconds to reach the ground.

b) It hits the ground with a velocity of -24.1 m/s.

To answer this problem, we'll use the equation of motion for a freely falling object:

[tex]d = v_{0}t + 0.5at^{2}[/tex], where d is the distance fallen, [tex]v_{0}[/tex] is the initial velocity (0 m/s in this case), a is the acceleration due to gravity (-9.8 m/s²), and t is the time elapsed.

We can use this equation to find t:

d = 0.5(-9.8)t²

65 = -4.9t²

t = √(65 / -4.9) = 2.45 s

Using this time, we can find the final velocity:

Answer with Explanation:

We can use the formula for acceleration to find the train's acceleration:

acceleration = (final velocity - initial velocity) / time

In this case, the initial velocity of the train is 60 m/s (since that's how fast it was going before it hit the brakes), the final velocity is 0 m/s (since the train comes to a complete stop), and the time it takes for the train to stop is 1 minute and 40 seconds, or 100 seconds.

So, plugging in the values we have:

acceleration = (0 m/s - 60 m/s) / 100 s

acceleration = -60 m/s / 100 s

acceleration = -0.6 m/s^2

Note that the negative sign indicates that the train is decelerating (slowing down), as opposed to accelerating (speeding up).

Fermat's theorem, also known as the principle of least time, states that the path taken by light or any other wave between two points is the path that minimizes the time taken. In fluid dynamics, this theorem can be applied to the flow of fluids in pipes or channels.

The basic idea is that the fluid will take the path that minimizes the time it takes for it to travel from one point to another. In other words, the fluid will follow the path of least resistance, where resistance is determined by the fluid's velocity and the diameter of the pipe or channel.

For example, in a fluid flow system with multiple branches or turns, the fluid will tend to follow the path with the smallest diameter or the least amount of resistance, as this will be the quickest path for the fluid to take.

This can be important in designing fluid systems, as it can affect the flow rate, pressure, and energy consumption of the system.

In summary, the correct application of Fermat's theorem to fluid dynamics involves considering the time it takes for a fluid to travel from one point to another and selecting the path that minimizes that time. This can help in optimizing fluid flow systems and improving their efficiency.

The stunt driver must drive off the ramp with a minimum speed of 53.93 m/s to successfully clear the 10 parked cars.

The trick driver needs to get an upward level free from 2.0 m and a flat distance of 24 m. To find the base speed required, we can involve the kinematic condition for vertical movement affected by gravity:

vf^2 = vi^2 + 2 * g * Δy

where vf is the last speed (extent of speed), vi is the underlying speed (size of speed), g is the speed increase because of gravity (9.8 m/s^2), and Δy is the adjustment of vertical level. We need the underlying speed (vi) so we can rework the condition:

vi = √(vf^2 - 2 * g * Δy)

For this situation, Δy = 2.0 m, g = 9.8 m/s^2, and vf = 0 (last speed is 0 in light of the fact that the vehicle lands on the ground).

vi = √(0 - 2 * 9.8 * 2.0) = √(- 39.2) = 6.27 m/s

This is the base vertical speed the vehicle should need to clear the 10 left vehicles. To find the base speed, we should likewise consider the even speed expected to cover the distance of 24 m.

v = √(vi^2 + vh^2)

where vh is the even speed. Since the even distance is 24 m and the hour of flight can be determined utilizing the upward movement condition, we can utilize the condition:

vh = d/t

where d is the flat distance (24 m) and t is the hour of flight.

t = √((2 * Δy)/g) = √((2 * 2.0)/9.8) = 0.447 s

vh = 24 m/0.447 s = 53.67 m/s

At long last, the base speed can be found as:

v = √(vi^2 + vh^2) = √(6.27^2 + 53.67^2) = 53.93 m/s (adjusted to 2 critical digits)

In this way, the trick driver should drive off the slope with a base speed of 53.93 m/s to clear the 10 left vehicles effectively.

The Pauling-Branson Award recognizes the contributions of Herman Russell Branson, (1914-1995), one of the first African American physicists to make crystallography the focus of his research.

The time it takes for the ball to return to the ground is approximately 3.06 seconds.

Resistance is the opposition to the flow of an electric current, or the opposition to any change. It is measured in ohms and is denoted by the symbol Ω.

When a baseball is thrown straight up, it follows a parabolic path under the influence of gravity. At the highest point of its trajectory, the baseball momentarily comes to rest before falling back down to the ground. To find the time it takes for the ball to return to the ground, we can use the kinematic equations of motion.

The first step is to determine the initial velocity and the final velocity of the ball at the highest point of its trajectory. At the highest point, the ball momentarily comes to rest, so its final velocity is zero. The initial velocity of the ball is 30.0 m/s (assuming that air resistance is negligible).

The kinematic equation that relates the initial velocity, final velocity, acceleration, and time is:

[tex]\mathrm{v_f = v_i + a \times t}[/tex]

where [tex]\mathrm{v_f}[/tex] is the final velocity, [tex]\mathrm{v_i}[/tex]is the initial velocity, a is the acceleration (due to gravity), and t is the time.

At the highest point of its trajectory, the ball reaches a height of

[tex]\mathrm{h =(v_i)^2 / (2 \times g) }[/tex]

where g is the acceleration due to gravity (9.81 m/s²).

This is the maximum height that the ball reaches, and it takes the ball the same amount of time to reach this height as it does to fall back down to the ground.

Using the initial velocity and acceleration due to gravity, we can calculate the maximum height reached by the ball:

[tex]\mathrm{h =(v_i)^2 / (2 \times g) }[/tex]

= (30.0 m/s)^2 / (2 * 9.81 m/s^2)

= 45.9 m

The time it takes for the ball to reach this height is given by the kinematic equation:

[tex]\mathrm{h = v_i \times t + (1/2) \times a \times t^2}[/tex]

Rearranging and solving for time, we get:

[tex]\mathrm{t = (v_f - v_i) / a = - v_i / a}[/tex]

where the negative sign indicates that we are looking for the time it takes for the ball to return to the ground, which is the time it takes to fall from the maximum height.

Substituting the values, we get:

t = - (30.0 m/s) / (-9.81 m/s²) = 3.06 s

Therefore, the time it takes for the ball to return to the ground is approximately 3.06 seconds.
