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
Based on the given spreadsheet, the database function that needs to be entered into cell I6 to find the average salary of all full-time employees is =AVERAGEIFS(D5:D34,B5:B34,"FT",C5:C34,">=1")
<h3>What does the AverageIfs formula find?</h3>You can use the AverageIfs formula to find the average of a specific group of numbers from a spreadsheet based on the shared categories that these numbers fall under.
After typing in the =AverageIfs function, you then input the range from which the category will be specified. In this case that is D5:D34. The next entry would be the range the category is picked from which is B5:B34. The function will be FT for Full time workers.
Then use C5:C34 to find out the number of dependents that are equal to or greater than 1.
The digit returned is the average salary of all full-time employees.
