Brainliest if correct Question 8 of 10 Which equation correctly relates mechanical energy, thermal energy, and total
energy when there is friction present in a system?
A. ME =
Etotal
Ethermal
B. ME = Etotal + Ethermal
C. ME = Etotal - Ethermal
D. ME = Ethermal - Etotal

B

Explanation:

C.

Explanation:

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
