A horizontal force of 675 N is needed to overcome the force of static friction between a level floor and a 300-kg crate. What is
the acceleration of the crate if the 675-N force is maintained after the crate begins to move and the coefficient of kinetic friction is 0.15

Answer:
The current would be same in both situation.
Explanation:
Given that,
Current I = 13 A
Number of turns = 23
We need to calculate the induced emf
Using formula of induced emf is
For N = 1
We need to calculate the current
Using formula of current
Put the value of emf
Now, if the number of turn is 22 , then induced emf would be
Then the current would be
Hence, The current would be same in both situation.
Explanation:
We have,
Speed of plane a is 900 km/h
Plane b is moving at a rate of
It is required to find which plane is faster. To find which plane is faster, we need to compare their speeds.
Speed of a plane a is 900 km/h and that of plane b is 50 km/h. So, we can say that plane a is moving faster.
