Answer:
Reaction force
Explanation:
A ball is thrown against a wall: The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off
That represents a proton!
Answer: 0.6
Explanation:
If we draw a free body diagram of the box we will have the following:
Net force in the x-axis:
(1)
Net force in the y-axis:
(2)
Where:
is the normal force
is the weight of the box
is the force exerted on the box
is the angle below the horizontal
is the friction force, being the coefficient of kinetic friction
Isolating from (1):

Substituting (3) in (2):
(4)
Finding :
(5)

Answer:
Explanation:
wavelength of light = 4 x 10⁻⁷ m
frequency = velocity in air / 4 x 10⁻⁷
= 3 x 10⁸ / 4 x 10⁻⁷
= .75 x 10¹⁵ Hz
= 75 x 10¹³ Hz.
Wave length = 4 x 10⁻⁷ m
= 400 x 10⁻⁹m
400 nm
colour of light having this wavelength in air is violet .
