Answer:
The angular momentum of the wheel is 
.
Explanation:
It is given that,
Mass of the wheel, m = 2.73 kg
Radius of the wheel, r = 31 cm = 0.31 m
Angular speed of the wheel, 
We need to find its angular momentum. It is given by :
I is the moment of inertia of the wheel, 
So, the angular momentum of the wheel is . Hence, this is the required solution.
<span>Beyond the philosophical objections there was also initially a very serious question about what force would be sufficiently large to continue pushing large plates of rock. The original proposer of the modern theory, Wegener, has not compelling answer to this question. We now know there are convection currents in the earth mantle under the continental plates that provide such a force.</span>
Answer:
True
Explanation:
Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
