I am pretty sure that the only statement which is true for particles of the medium of an earthquake P-wave is being shown in the option : b)vibrate parallel to the wave, forming compressions and rarefactions. As you know, it can be formed in two ways : from alternating compressions and rarefactions or primary wave. I bet you will agree with me.

<h3>
Answer: A) 3 pronged cord</h3>
Explanation:
One prong is known as the hot wire, where the electricity comes in, while the second prong is the neutral wire and electricity leaves. Recall that a circuit must be made for electrons to flow. This means that electrons enters your house through the transmission wires and then the electrons leave along the same lines they entered (just along a different wire).
This set up describes a 2 pronged cord. Adding a third prong allows for a grounding to happen. In the event of an electrical surge, when too many electrons are flowing, disaster is likely to happen without some kind of safety features. The grounding prong allows electrons to seek the ground. You can think of it like a drain in a bathtub when too much water gets in the tub.
Answer:
Part a)
Part b)
Explanation:
Initial speed of the flywheel is given as
initial angular speed is given as
Number of revolutions
angular displacement is given as
now we have
Part a)
final angular speed of the wheel is given as
Part b)
If the final angular speed becomes zero then time taken by the wheel is given as
Now total number of revolution that it makes is given as
7) p=w/t
2620/0.2
=13100W
8) W=pt
40*30
=1200 J
9) transformed
