I reported this question by accident, I am sorry.
Anyways, there is no electric field at the center of a charged spherical conductor because all the charged particles are at the edges and because of the complete cancellation everywhere.
Answer:
0.168°C
Explanation:
The frictional force between the palms enables rubbing and initiates the heat deposed.
The energy generated per rub is;
The force × distance
Hence we have; 71.3 N×0.0750m
Hence for 11 rubs we have; 11× 71.3 N×0.0750m= 58.82J
Now this heat acquired by the tissue is the same as mass of tissue × specific heat capacity of tissue × temperature rise;
Expressed mathematically as;
58.82=0.100 kg×3500 J/(kg · °C)×∆T
∆T= 58.82/ 0.100 ×3500 =0.168°C
Answer: Yes.
Explanation: Because of the crystalline structure.
Answer:
The mnemonic I can use to memorize the metric prefixes in this order is: Gigantic Monsters Killed One Million Men Napping Peacefully. All right, so again, gigantic monsters killed one million men napping peacefully.
This is EXACTLY the same scenario as the skydiver jumping
out of the airplane, except the whole thing is turned on its side.
==> The skydiver leaves the airplane.
The force of gravity on him (his weight) makes him accelerate down.
But the air resists his downward motion.
The faster he falls, the more UPWARD force the air exerts on him.
The more upward force the air exerts, the less he accelerates down.
When his falling speed is great enough, he stops accelerating, and
falls with a constant speed. He calls that speed his 'terminal velocity'.
==> The submarine turns on its engines, at maximum power.
The force of the engines makes the sub accelerate forward.
But the water resists its forward motion.
The faster it moves, the more BACKWARD force the water exerts on it.
The more backward force the water exerts, the less it accelerates forward.
When the forward speed is great enough, it stops accelerating, and moves
with a constant speed. I don't know if they use the same term in submarines,
but you might say that speed is the 'terminal velocity' in water.
