A man inside an insulated metallic cage does not receive shock when the cage is highly charge .explain.
Luba_88 [7]

A man inside an insulated metallic cage does not receive shock when the cage is highly charged because the whole charge reside on outer surface of the cage.

If the cage was a non-conductive cage, then the current cannot pass through the cage so it cannot affect the person in the cage.

For example- If you are seated in a car (metal body) and the car is hit with lightning, it is very unlikely that the person in the car would be hit with the lightning.

What is the momentum p if the mass m is doubled?<br> Vzp<br> 1) р<br> 2) 2p<br> 3) 4p
aliina [53]

Answer:

<em>Correct answer: 2) 2p</em>

Explanation:

<u>Momentum</u>

Momentum is a measurement of mass in motion or how much mass is in how much motion. The symbol for momentum is p and is defined as:

p = m . v

Where m is the mass of the object and v is the speed. Note this is the scalar version of the formula because both p and v are vectors.

Suppose the mass of the object is doubled to 2m, then the new momentum is:

p' = (2m) . v = 2 m . v

Or, equivalently:

p' = 2p

Correct answer: 2) 2p

Two blocks joined by a string have masses of 6 and 9 kg. They rest on a frictionless horizontal surface. A 2nd string, attached
Tom [10]

Answer:

12N

Explanation:

Suppose the string mass is negligible, the total mass of the 2 block system is 6 + 9 = 15 kg

So the acceleration of the system when subjected to 30N force is

a = F / M = 30 / 15 = 2 m/s2

So both blocks would have the same acceleration, however, the force acting on the 6kg block would have a magnitude of

f = am = 2 * 6 = 12N

This is the tension in the string between the blocks
