Answer:
I = 2 kgm^2
Explanation:
In order to calculate the moment of inertia of the door, about the hinges, you use the following formula:
(1)
I: moment of inertia of the door
α: angular acceleration of the door = 2.00 rad/s^2
τ: torque exerted on the door
You can calculate the torque by using the information about the Force exerted on the door, and the distance to the hinges. You use the following formula:
(2)
F: force = 5.00 N
d: distance to the hinges = 0.800 m
You replace the equation (2) into the equation (1), and you solve for α:
Finally, you replace the values of all parameters in the previous equation for I:
The moment of inertia of the door around the hinges is 2 kgm^2
Answer: a) The Answer to the question is option a) None of it.
Explanation:
The reason is because according to the law of conservation of energy Energy can neither be created nor destroyed but can be transformed from one form to the other. Therefore none of the kinetic energy was dissipated, rather it was transformed to another form of energy.
Answer:
Wycleff is on block 1, Lilly is on block 4, Emilia is on block 12, and Quincy is on block 17.
Explanation:
Wycleff was at block 1 and heard a low pitch sound the whole time, so the police car must have been moving away from him.
Lilly observed was in block 4 change in pitch first. So the car must have passed her first.
Emilia was at block 12 observed a Doppler effect after Lilly. So the car passed her after passing Lilly
Quincy was at block 17 so she heard a high pitch sound the whole time, so the police car must have been moving toward him.
