Answer:
0.52 m
Explanation:
The motion of the studnet is an accelerated motion, with constant acceleration 
(acceleration of gravity) toward the ground. We can find the distance covered by the student (which is equal to the height from which he falls) by using the SUVAT equation:
where
v = 3.2 m/s is the final speed
u = 0 is the initial speed
a = 9.8 m/s^2 is the acceleration
d is the distance covered
By re-arranging the equation, we find:
Answer:
B. The algebraic sum of the two electric potentials is determined at a distance r/2 from each of the charges, making sure to include the signs of the charges.
Explanation:
Total electric potential is the sum of all the electric potential. And because electric potential is a scalar quantity you have to account for the signs.
