As per Newton's III law every action has equal and opposite reaction
So here we can say that
every body which apply force on other body must have a reaction force of same magnitude in opposite direction
So here if ball hits the ground by 50 N force then the ball must have a reaction force on itself with same magnitude and opposite direction
the magnitude of the force will be 50 N
and its direction is opposite to the force that ball apply on the floor
Try this option, the answers are marked with colour.
Electrostatic (it’s a combined word) that’s all what i know honestly, hope it helps:)
Ok so we know that electric power is:
If we express resistance.
Now if you have 100W of power you will probably get a bigger resistance than with 40W of power.
However here it says that the resistance of 40W bulb is bigger than 100W bulb. Which means the statement is incorrect.
Hope this helps.

Answer:
distance is 139.2 cm
image is inverted and virtual
and 79.36 cm in front of 2nd lens
Explanation:
Given data
convex focal length = 24 cm
distance = 50 cm
concave focal length = -42 cm
light bulb height = 2 cm
distance = 29 cm
to find out
Determine the distance and orientation and image real or virtual
solution
we apply here lens formula for convex
1/f = 1/p + 1/q
here f = 24 and p = 29 so find q
1/24 = 1/29 + 1/q
q = 139.2 cm
so distance is 139.2 cm
and
lens formula for concave
f = - 42 and p = 50 - 139.2 = -89.2 cm so find q
1/f = 1/p + 1/q
- 1/42 = - 1/89.2 + 1/q
q = −79.36 cm
so image is inverted and virtual
and 79.36 cm in front of 2nd lens
