4. A ball fell to the floor after rolling off a table. What was true of the ball's energy as it fell? A. The ball's potential energy must have remained the same as it fell to conserve
mechanical energy.
B. The ball's kinetic energy must have remained the same as it fell to conserve mechanical
energy.
C. The ball's potential energy decreased as it fell, so its kinetic energy must have increased
to conserve mechanical energy.
D. The ball's potential energy decreased as it fell, so its kinetic energy must have decreased
to conserve mechanical energy.
5. A child picks a ball up from the ground, then places it on a table. The ball rolls on the table's
surface. Which statement is true?

C

Explanation:

The ball was gathering potential energy as it was rolling, and as it falls the kinetic energy increased as it fell faster and faster

from my own personal expirence food stamps has alot this makes it eaiser so we can affod bills and so we can life a better lifestyle not needing to worry about paying actual money to buy food since most people spend 100-300 dollars a month on food so this alot so we can afford other bills and other stuff we need

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
