Answer:
You could put a pressure stick against the pressure and see the pressure or estimate it from the power its coming out.
Explanation:
Given that,
Electrical energy of the motor = 2280 J
Kinetic energy = 1606 J
Wasted energy in thermal and sound energy = 550 J
To find,
The efficiency of the motor in percent.
Solution,
Efficiency is defined as the ratio of useful output energy to the total energy.
Total energy = 2280 J
Useful energy = 1606 J

So, the efficiency of the motor is 70.43%.
The answer should be B. Fault.
project ideas for what exactly?
circular motion.
cent acc = r omega^2 ... omega is ang vel ... omega=2pi/T ,,,
9.8=rx(2pi/T)^2
if r is known, solve for T
