Explanation:
Answer:
7.5Watts
Explanation:
Given parameters:
Force of lift = 25N
Height = 3.6m
Time = 12s
Unknown:
Power output = ?
Solution:
Power is the rate at which work is done ;
Power =
Power = = 7.5Watts
The correct answer is amplitude
Answer:
(I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
Explanation:
Given that,
Magnetic field = 0.080 T
Velocity of wire segment = 78 m/s
Component in x direction = 18 m/s
Component in y direction = 24 m/s
Component in z direction = 72 m/s
Length = 0.50 m
We need to calculate the motional emf induced between the ends of the segment
Using formula of emf
Put the value into he formula
(II). If the wire segment is parallel to the y-axis then the angle between B and v is zero.
We need to calculate the motional emf
Using formula of emf
Here,
Hence, (I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
