Answer:
The current in the motor in this case is 13.2 A
Explanation:
Given:
Resistance 5 Ω
Emf V
Induced emf V
When motor run at half speed due to load increased then induced emf is also reduced to half of its value
So new induced emf in our case is given by,
V
Where
A
Therefore, the current in the motor in this case is 13.2 A
Answer:
Resultant velocity will be equal to 6.10 m/sec
Explanation:
We have given a motorbike is traveling with 5 m/sec in east
And a current is flowing at a rate of 3.5 m /sec in north
We know that east and north is perpendicular to each other
So resultant velocity will be vector sum of both velocity
So resultant velocity
So resultant velocity will be equal to 6.10 m/sec
