I think it's D. Usually, to find the volume of an irregularly shaped object, you put it in water with a labeled beaker to measure how much the water rises. The balance would be used to measure the mass in grams.
1. Resistor
2. Insulator
3. Current
4. Semiconductor
5. Conductor
True. E=energy M=mass c= speed of light
The answer is B. Have a good day! :)
Answer:
9.97sec
Explanation:
To solve for the period we can derive the formula as follows
ω=2πf
ω=2π/T
v=rω
v=2πr/T
T=2πr/v
T=9.97sec
