Answer:
75.5degrees
Explanation:
Magnitude of magnetic flux= BA
If rotated through an angle= BAcos theta
= (0.25)BA=BAcos theta
= costheta= 0.25
= theta= cos^-1 0.25
=75.5degrees
All vibrating bodies produce sounds in molecules of the medium they are as air,wood,water
Answer: vf = 32 m/s
Explanation: Solution:
Use the formula for acceleration:
a = vf - vi / t
initial velocity vi = 0 since it is at rest.
derive to find vf:
vf = at + vi
= 8.0 m/s² ( 4.0 s ) + 0 m/s
= 32 m/s
Answer:
The velocity is
Explanation:
From the question we are told that
The initial speed is
The cross -sectional area of the first pipe is
The cross -sectional area of the second pipe is
Generally from continuity equation we have that
So
