Answer:
Part a)
Part b)
Explanation:
Since the ball and rod is an isolated system and there is no external force on it so by momentum conservation we will have
here we also use angular momentum conservation
so we have
also we know that the collision is elastic collision so we have
so we have
also we know
also we know
so we have
now we have
Part b)
Now we know that speed of the ball after collision is given as
so it is given as
Answer : 5m/s
Explanation:the formular for velocity is distance /time or you can say displacement /time. Then it would then be
100/20 =5m/s
Dead starts bursting new ones being born, maybe more dwarf planets
A wave can be described as the disturbance of particles in an area. Think about it this way: particles (matter) carry energy. For all the laws of physics to work, this energy must be "traded" somehow. This happens by miniscule vibrations in the particles, which are apparent disturbances. This creates a wave, and therefore a wave is, indeed, a disturbance.<span />
