Answer: 7840N
Explanation:
Given that
Potential energy = ?
Mass of sled = 20-kg
Distance = 40 meters
Acceleration due to gravity = 9.8m/s^2
Recall that potential energy is the energy possessed by a body at rest
i.e potential energy = mass m x acceleration due to gravity g x distance h
P.E = mgh
P.E = 20kg x 9.8m/s^2 x 40m
P.E = 7840N
Thus, the potential energy of the sled is 7840N
Answer:
The third choice: 
Explanation:
The cork is positively charged, therefore we know tat there must be excess of positively charged protons present.
The charge 
of a proton is
;
therefore, the number 
that makes up a charge of 
is
which is the 3rd choice.
