2. a poetry reading = to entertain
3. an advertisement = to persuade
4. a small group assignment = to collaborate
Explanation:
1. A "breaking news" tells people of what is happening in the society. It <em>informs </em>them of the occurrence of an important event such as the plane crash of Kobe Bryant.

Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is

The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
