Why is a spectrum of colors produced when white light passes through a prism?

Physics

Answer:

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.

The spectrum is produced because different colours of light travel at different speeds in glass.


The spectrum is produced because different colours of light travel at different speeds in glass. Red light is slowed down least by glass and is refracted least. Violet light is slowed down most by glass and is refracted most. As a result, the coloured light spreads out to form a spectrum of white light.

A gun can fire a bullet at 540 m/s. If the gun is aimed at an angle of 55o above the horizontal and fired, what will be the hori
lisabon 2012 [21]

Answer:

Explanation:

The <u>initial</u> vertical velocity is 540sin55° = 442.342103... 442 m/s

The <u>initial</u> horizontal velocity is 540cos55° = 309.731275... 310 m/s

In the real world, both initial velocities would be reduced by air resistance and vertical velocity will be altered by gravity.

A car travels at a constant speed up a ramp making an angle of 28 degrees with the horizontal component of velocity is 40 kmh^-1
Hoochie [10]

Answer:

Vx = 35.31 [km/h]

Vy = 18.77 [km/h]

Explanation:

In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.

v_{x} = 40*cos(28)\\V_{x} = 35.31 [km/h]

In order to find the vertical component, we must use the sine function of the angle.

V_{y}=40*sin(28)\\V_{y} = 18.77 [km/h]

Which of the following is an expression of Newton's second law? O A. The acceleration of an object is determined by its mass and
dangina [55]

Answer: is A

The acceleration of an object is determined by its mass and the net force acting on it.

Newton's second law says that "F=ma". what this means is that the force you apply to an object is equal to its mass times how fast it is accelerating.

Hope it helped.

Marina CMI [18]
The problem ask to calculate the bullet's flight time and the bullet's speed as it left the barrel. So base on the problem, the answer would be that the flight time is 0.076 seconds and the speed of the bullet is 657.9 m/s. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.
