In general, impulse = F x time=mxv
if J is the impulse, J=<span>Ft, J=mv, and J=p because p=mv
possible formulas are
</span><span>J = Ft, J = mv and J = p</span>
Answer:
didya know this is chrating. everyone has a breain and so do u .
Explanation:
use and u will pass
The answer to your question is meters.
Given that,
Mass of the stone, m = 400 g = 0.4 kg
Initial speed, u = 20 m/s
It is climbed to a height of 12 m.
To find,
The work done by the resistance force.
Solution,
Let v is the final speed. It can be calculated by using the conservation of energy.

Work done is equal to the change in kinetic energy. It can be given as follows :

So, the required work done is 32.99 J.
"Dispersion forces" is the one intermolecular force among the following choices given in the question that <span>explains why iodine (I2) is a solid at room temperature.
