To solve this problem it is necessary to address the concepts related to Torque as a function of the force and distance where it is applied and the moment of inertia from which the torque, moment of inertia and angular acceleration are related.
By definition the torque is defined as
Where,
F = Force
r = Radius
For our values we have:
Consequently the calculation of the moment of inertia would then be given by the relationship
Replacing with our values
The moment of inertia of the boxer's forearm 
Physics is everything in life technically. and there is a lot of types of physics. also it is math and reading mixed together.
Hypotheses and theories related to each other since hypotheses are used in creating a theory. Hypotheses are explanations for some phenomenon that are still proposed. When these are validated and proved, they are accepted by the public as theories and are used to explain natural phenomenon.
Answer:
15%
Explanation:
Step one:
Given data
Energy source= 300J
Useful energy = 45J
Waste energy = 255J
Required
The efficiency of the solar system
Step two:
The efficiency is computed by factoring only the useful work and the energy source
Efficiency= 45/300*100
Efficiency= 0.15*100
Efficiency= 15%
Hey! I just started AP Physics 1 as well.
Lets break it down:
Displacement is the change in the position of a vector.
Net means total
This means that Net displacement means the addition of displacements. Also said as the "vector sum of the individual displacements".
This is all I know. Good luck!
