Here if we consider bullet and gun as a system then we can say that momentum of the system will remain conserved
so we will have
now we know that
now we will have
so gun will recoil with speed 6.67 m/s
your answer will be D Strong nuclear force is most like electric because they are both related to distance.
Answer:
Evaporation
Explanation:
Evaporation occurs when a liquid changes to a gas. During evaporation, molecules gain enough thermal energy to escape from the liquid surface into the air as water vapor. Water-vapor molecules spread out, breaking completely free of each other, and then disperse or spread out among the other gas molecules in the air.

In order to find it's square root, we could make it into two square roots.
Let us find the square roots of both radicals seprately.
Each pair of a number inside square root gives a number out .
Therefore,
88.6 what? 88.6 kg?
If 88.6 kg, then weight is 9.8*88.6
which is roughly 10*88.6 or 860 Newtons. Force weight=mass*gravity, where gravity =9.8( m/s^2)
