The answer & explanation for this question is given in the attachment below.
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
Answer:
phones = {'John': '1234567', 'Julie' : '7777777'}
Explanation:
In the code given in the question phones dictionary contains contains two keys John and Julie and have the values '5555555' and '7777777' respectively. Now in the code the key John in the dictionary phones is assigned the value '1234567' .So the value corresponding to the key John becomes '1234567'.
Time management,they wouldn’t have enough time to read it and they would become more stressed out
Answer
sorry I only know how to make balloons :(
Explanation:
For the balloons the recipe that one is:
- you will need 6 latex
To make latex you will need two different elements one is 5 Carbon and the other one is 8 Hydrogen ( don't use crafting table to do it use the compound creator)
-Dye ( whatever color you want)
-Helium
-lead
Instructions
on the crafting table the latex will go on the sides (3 on the left and 3 on the right). The dye goes on top, the Helium in the middle and the lead at the bottom and there you go a balloon
