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:
B. A car sits at rest at a stop sign.
The electromagnetic radiation that will be smartest to use is gamma rays.
<h3>
Electromagnetic radiation</h3>
These are waves that does not require material medium for their propagation.
The wave with high frequency has a greater rate of penetration while those with high wavelength has lesser rate of penetration.
Thus, it will be smart to use the wave with high frequency, which means a low wavelength. The electromagnetic radiation with the highest frequency and low wavelength is gamma rays.
