Answer:
Energy loss per minute will be
Explanation:
We have given the star produces power of
We know that 1 W = 1 J/sec
So
Given time = 1 minute = 60 sec
So the energy loss per minute
We multiply with 60 we have to calculate energy loss per minute
Answer:
a = 0.45 m/s²
Explanation:
The given question is ''Calculate the acceleration that produces a force of 40 N on a body with 88 kg of mass".
Given that,
Force, F = 40 N
Mass of the body, m = 88 kg
The net force acting on the body is given by :
F = ma
Where
a is the acceleration of the body
So, the required acceleration is 0.45 m/s².
