Water pressure is greater at the bottom of the deep end of the pool when compares to the shallow end of the pool because all of the weight of the water is compressed and pushed down (there is more volume on the deep side).
Think of it like this:
You wear your hat - only 1. It's normal, you only feel the hat fit on. Now imagine that you wear about 10 hats, it starts to feel uncomfortable and after a while, your neck will get stiff due to the pressure of the hats pushing down on your spinal cord. Now imagine 100 hats - the deeper you go, the more pressure is forced on you.
Answer:
The induced current in the resistor is I = BLv/R
Explanation:
The induced emf ε in the long bar of length, L in a magnetic field of strength, B moving with a velocity, v is given by
ε = BLv.
Now, the current I in the resistor is given by
I = ε/R where ε = induced emf in circuit and R = resistance of resistor.
So, the current I = ε/R.
substituting the value of ε the induced emf, we have
I = ε/R
I = BLv/R
So, the induced current through the resistor is given by I = BLv/R
Air or any sort of gas is not that good in conducting heat in relation to other materials.
<span>since foam consists of many bubbles with trapped gas it both stops convection by simply being in position, and prevents conduction of heat through it, due to the gas inside</span>
From the things on that list, the copper wire has the least resistance ... unless it happens to be several miles long.
