Answer:
(A) Angular speed 40 rad/sec
Rotation = 50 rad
(b) 37812.5 J
Explanation:
We have given moment of inertia of the wheel 
Initial angular velocity of the wheel 
Angular acceleration 
(a) We know that 
We have given t = 2 sec
So 
Now 
(b) After 3 sec 
We know that kinetic energy is given by 
A. The vector goes from (4,0) to (3-2)
(x,y)
Answer: Long Answer...
Explanation: Most of the time, chemical energy is released in the form of heat, and this transformation from chemical energy to heat, or thermal energy, is called an exothermic reaction. Next, there are two main types of mechanical energy: kinetic energy and potential energy.
Answer:
1.because of the heat produced by the socat
2. they should have control how they placed the heater
3. because the water is to much
4.because is different from the question
5. because that is how the question is
