Equal to 50
law of reflection: angle of incidence equals angle of reflection
In one quadrant there are 90 degrees.
Answer:
mass of an object
Explanation:
because mass of an object changes it’s force
Given: Mass m = 60 Kg
Weight W = 96 N
Required: Acceleration due to gravity, g = ?
Formula: W = mg
g = W/g
g = 96 Kg.m/s²/60 Kg (note: this is the derive unit for Newton "N")
g = 1.6 m/s²
