Answer:
M = 0.730*m
V = 0.663*v
Explanation:
Data Given:

Conservation of Momentum:

Energy Balance:

Substitute Eq 2 into Eq 1

Using Eq 1

A type of material that tries to prevent the flow of thermal energy is called an insulator.
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
Answer:
a) 1.2*10^{-3}cos(1.25t)
b) 0.49mV
Explanation:
a) The coil rotates periodically with period T. Hence, we can write the variation of the magnetic flux with a sinusoidal function, and with max flux NAB. Thus, we have that:

where we have used the values given by the information of the problem for N B and A.
b)
the emf is given by:

hope this helps!!
Because field lines don’t all go in to the pole. The bottom half go outwards not inwards.
