Answer:
80×5×10=4000J
so therefore, work done on the body is 4000J
That is a vector. It is a combination of direction and velocity. (You can think of Vector from Despicable Me to help you remember the term)

Hey there!
No, that would be a biologist. Biologists study biology, or life. They're focused on life cycles, cells, evolution, and so much more.
Physicists focus on physics. They learn about forces, motion, and the study of the universal forces like gravity, momentum, and speed. Just like mathematics, they study patterns and look for new discoveries to be found in the fields of science, physics, and even mathematics.
Hope this helps!
Answer:

Explanation:
= Permittivity of free space = 
A = Area
h = Altitude = 600 m
Electric flux through the top would be
(negative as the electric field is going into the volume)
At the bottom

Total flux through the volume

Electric flux is given by

Charge per volume is given by

The volume charge density is
