Which would have the greatest gravitational potential energy?
45 kg dog on a 5 foot high rock
20 kg dog on a 2 foot high rock
20 kg dog on 2 foot high log
45 kg dog on 2 foot high log

45 kg dog on a 5 foot high rock

Step-by-step explanation:

The equation for potential energy is PE = mgh, which is mass x 9.81 x height

You increase either the height or the mass you will increase the PE.  Since the 45 kg was the most and 5 foot was the highest thus it would have the highest PE.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
