Answer:
The pressure of the solid on the surface depends on the area of contact. The area of contact between the two surfaces. The greater the force or the smaller the area the greater the pressure.

Answer:
<em>1. c. Same in both</em>
<em>2. a. Case 1</em>
<em></em>
Explanation:
1. The balls are identical in all sense, which means that if they are dropped from the same height, they should posses the same kinetic energy just before they collide with either the concrete floor or the stretchy rubber. Also, since they reach the same height when they bounced of the concrete floor or the piece of stretchy rubber, it means that they posses the same amount of kinetic energy at this point. Since their kinetic energy at these two points are the same, and they have the same masses, then this means that their momenta at these two instances will also be equal. Since all these is true, then the change in the momentum of the balls between the instance just before hitting the concrete floor or the stretchy rubber material and the instant the ball just leave the floor or the stretchy material is the same for both.
2. The ball that falls on the concrete will experience the greatest force, since the time of impact is small, when compared to the time spent by the other ball in contact with the stretchy rubber material; which will stretch, thereby extending the time spent in contact between them.
The name of this landmas is known as <em>
</em>
Pangaea, was a supercontinent that existed during the late
Paleozoic and
early
Mesozoic eras. It formed approximately 300 million years ago and began to break apart after about 100 million years.

Answer:
The second option : The closer a star is to us, the more parallax it exhibits.
Explanation:
When a star is close to the observer, it is possible to better see the difference in movement and distant because of space behind or other stars close to it, so we can measure distances from these celestial bodies by using parallax. Just as trees seem to move more than the mountains in the background during a car trip, so do stars, but in a much more imperceptible way. The closer to the viewer the more parallax will display.
Answer: a.information level
