Answer:
third
Explanation:
for every action there is an equal and opposite reaction
example
bouncing ball
ball receives a force from the ground due to collision
that same force causes the ball to bounce off the ground
first law:
inertia
example
stuff in space doesn't move unless its pushed
then it keeps going unless something stops it
second law
force = mass times acceleration
example
harder you push a cart the faster it goes
the less a cart weighs the faster a cart goes

Answer:
C. Takes heat in, does work, and loses energy heat.
Explanation:
Heat engine is a system makes use of thermal energy (heat) to in order to do mechanical work.
This occurs by converting the heat into mechanical energy. This energy is then used to do work.
The key characteristic of a heat engine is that the substance with which work is done by, goes from a higher temperature to a lower temperature.
Hence, it loses heat as it does work.

Explanation:
F=5.6×10^-10N
R=93cm=0.93m
let take m1 and m2 =m²
according to newton's law of universal gravitation
F=m1m2/r²
F=m²/r²
now we have to find masses
F×r²=m²
5.6×10^10N×0.93m=m²
5.208×10^-9=m²
taking square root on b.s
√5.208×10^-9=√m²
so the two masses are m1=7.2×10^-5
and m2=7.2×10^-5
