Answer : (D) " in the opposite direction of "

Explanation :

It is given that when object A collides with object B and bounces back. This shows that the collision is elastic. There are two conditions for elastic collision :

(1) The momentum remains conserved

(2) Kinetic energy is conserved.

We know that momentum is defined as the product of mass and velocity. After bouncing back, the direction of velocity gets changed. So, the final momentum is in the opposite direction of its initial momentum.

So, the correct option is (D).

When object A collides with object B and bounces back, its final momentum is in the opposite direction of its initial momentum. The correct option among all the options that are given in the question is the last option or option "d". This type of collision is elastic in nature as the ball bounces back and so the momentum has to be in the opposite direction of the initial momentum. <span />

D.

The gravitational of a body is possessed by the body due to the virtue of its position.

The formula for gravitational potential energy is,

                                P.E = mgh joules

Substituting the values

196*9.8*250= 49k

What causes winds to form?
nlexa [21]
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

Technician A says that shop air pressure usually ranges from 100–150 psi. Technician B says shop air pressure is around 300 psi.
mr Goodwill [35]

Answer:

technician A.

Explanation:

Commonly,  air pressure rating of standard shop air compressor's is between the range of 100 psi and 150 psi. And over the years since, the plant pressure creep's up , the level of pressure increases from 100 psi to at max 150 psi but not more than that. Therefore, in the given question technician A is correct and technician B is incorrect.
