It is the maximum distance from the equilibrium point of the pendulum.
Explanation:
I think it will increase a little bit ... just image ... if the temperature is 0, the velocity will be 0 too. because the vibration of atom is so weak and the sound cant progation.
Water has a high specific heat capacity. Oil has a smaller heat capacity.
Answer:
we know that current = charge/time
Explanation:
therefore,
A = 8000/120
A => 66.666.... amperes
