Answer:
it right. Its The Iron Nail i just did it and i got correct (:
Explanation:
<h2>If the distance between Earth and moon is increased , the gravitational force will decrease by a proportional amount .</h2><h2>The iron filings sprinkle around the magnet are arranged in regular pattern . The reason for this is that magnet can attract magnetic substances through various materials .</h2>
Explanation:
If the distance between Earth and moon is increased , the gravitational force will decrease by a proportional amount .
The iron filings sprinkle around the magnet are arranged in regular pattern . The reason for this is that magnet can attract magnetic substances through various materials .
Answer:
The kinetic energy of the disk is 254.4 J.
Explanation:
The kinetic energy of the disk is given by:
The moment of inertia of the solid disk is:
The mass is:
Now, we need to find the angular acceleration as follows:
Also, the torque is related to the tangential force:
Now, we can find the angular speed:
since it is started from rest
Finally, the kinetic energy of the disk is:
Therefore, the kinetic energy of the disk is 254.4 J.
I hope it helps you!
Answer:An atomic nucleus consists of protons and neutrons, collectively called nucleons. Although protons repel each other, the nucleus is held tightly together by a short-range, but very strong, force called the strong nuclear force.
