The answer is A) 1000 J
According to the law of conservation of energy, the total energy before an action is always equal to the total energy after the action.
So that is, the total energy is 8000J found as potential energy, 7000J has transformed into kinetic energy, then the thermal energy should be the remaining 1000J.
Hope this helps.
Answer:
5m/s/s
Explanation:
10N bc you subtract 10N from 20N and you get 10
a=f/m
F=10N
m=2kg
10/2=5
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.
