Force = mass x acceleration
25N = 0.40kg x acceleration
25N/0.40kg = acceleration
acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²
So your acceleration is 62.5 meters per second squared
Answer:
C) Index of refraction
Explanation:
Index of refraction also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a given material.
The formula for Index of refraction is:
n = c ÷ v
where n represents Index of refraction,
c represents speed of light in a vacuum,
v represents speed of light in a given material.
The speed and direction of light changes when it moves from one medium to another. The change in direction is basically called refraction.

An ionic bond is made between a metal and a non-metal
You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.
Answer:
1. Primary or P waves are push and pull waves
2. Secondary, S or Shear Waves are also called transverse wave
3. L or surface waves reach the earth's surface after P and S waves
