Odd though it seems at first, gravity is pulling the cat down while the floor is pushing the cat up - in equal amounts. Forces are absolutely acting on the cat but they balance - so there is no net force.
Answer:
An electric field is a region around a charged object where the object's electric force is exerted on other charged objects. Electric fields get weaker the farther away they are from the charge. An electric field is invisible. You can use the field line to represent it.

130 km at 35.38 degrees north of east
Explanation:
Suppose the HQ is at the origin (x = 0, y = 0)
So the coordinates of the helicopter after the 1st flight is
After the 2nd flight its coordinate would be:
So in order to fly back to its HQ it must fly a distance and direction of
north of east
A point b cause at a it’s gaining kinetic energy and at b it has the most kinetic energy
Answer:
Explanation:
mass of superman, M = 104 kg
initial velocity of superman, U = 0
mass bullet, m = 3.93 g
initial velocity of bullet, u = 855 m/s
Let the velocity of superman after hitting by the bullet is V.
M x 0 + m x u = M x V + m x 0
3.93 x 10^-3 x 855 = 104 x V
V = 0.032 m/s
