Answer:
b. less than
Explanation:
Moment of inertia decreases as angular velocity increases. Therefore, since the minute hand is faster than the hour hand, it is safe to say that the moment of inertia of the minute hand is less than the moment of inertia of the hour hand?
a. The wheel accelerates uniformly, so its constant acceleration is equal to the average acceleration:
b. Yes. Since
then multiplying by 2 means we double the change in angular speed, but the wheel starts from rest so only the final angular speed gets doubled.
Explanation:
This due to thermal insulation of some of the roof.
An insulator is body is a poor conductor of heat and will require high thermal energy to cause temperature changes.
- A house with a roof that is thermally insulated will have poor heat conduction.
- Since little heat is conducted, there wont be enough thermal energy to melt the snow.
- Thermal energy is directly related to heat.
- A house that is not insulated will absorb a lot of heat.
- This will cause the snow to melt very fast.

This loss of stable old ice has set up additional losses of sea ice cover each summer because the thinner younger ice is more easily melted during the recent warmer summers. Because of their dependence upon the sea ice for food, these changes can directly affect the carrying capacity of the Arctic for polar bears. Mark this as the brainliest answer please
Vf=√30²+100²
Vf=104 m/s
|Ф|=tan inverse of |100÷30|
Ф= 73 degrees
Therefore the resulting velocity of the airplaine is 104 m/s [ 73 degrees N of W]
