Answer:

when the ray passes from ice to perspex it must approach the normal

Explanation:

This is an exercise in refraction of light, the process is governed by the expression

      n₁ sin θ₁ = n₂ sin θ₂

where we use index 1 for the incident medium and subscript 2 for the scattered medium.

In our case, medium 1 is ice with the lowest refractive index.

           sin θ₁ = n₂ / n₁   sin θ₂

To fulfill this equation, if the ray travels through the medium 1 ice with an angle θ₁, the angle in the medium 2 perspex must be smaller so that the sine is smaller, so when the ray passes from ice to perspex it must approach the normal

What is the Kinetic Energy of a tennis ball after 40.0cm of freefall?
OlgaM077 [116]
The kinetic energy is the same as the potential energy of raising it 40cm (0.4m). That's mgh where m is mass of ball. Its then 3.924*m, whatever m is equal to in kg.

The distiction between long and short term memory
RUDIKE [14]

Answer:

The main difference between short term and long term memory is that the short term memory stores data temporarily while the long term memory stores data permanently. Moreover, the short term memory is volatile while the long term memory is nonvolatile. Memory is the component in a computer that stores data and information.
