Answer:
divide 10 by 50.
Explanation:
Because its time over speed 10/50
D. Collect more evidence and try to convince the other scientist
Answer:
56 kg
Explanation:
The change in potential energy of the man is given by:

where
m is the man's mass
g is the gravitational acceleration
is the change in height of the man
In this problem, we have:
is the gain in potential energy
g = 9.8 m/s^2 is the gravitational acceleration
is the change in height
Re-arranging the equation and substituting the numbers, we find the mass:

Electricity flows from positive to negative
