Answer:
the rocks have the same amount of thermal energy
Torque [Nm] = Force [N] x Force arm [m]
C=F*b=20*0.20=4 Nm
The correct answer is C
Answer:
Pressure will be 
Explanation:
We have given mass of the women m = 65 kg
Radius of the heels r = 0.578 cm = 0.00578 m
We have to find the pressure
We know that pressure is given by

So force F = mg = 65×9.8 = 637 N
Area 
So pressure 
Answer:
Current that reverses direction in the regular pattern is called an alternating current, abbreviated as 'AC'.
Explanation:
hope this helps!
Using the formula F = m*a. where F is the force, m is the mass and a is the acceleration you can use it for each. As long as there are no other forces towards the body in both cases :
F = m*a
F = 50*3
F = 150 N
