Explanation:
The momentum of any object is given by the product of mass and velocity with which it is moving i.e.
p = mv
Momentum is a vector quantity. It means we can resolve it into rectangular components.
If the car is moving with a speed of 20 m/s in North direction, its momentum is given by :
.....(1)
If the car is moving with a speed of 20 m/s in East direction, its momentum is given by :
....(2)
It is clear from equation (1) and (2) that the magnitude of momentum is same but the direction of momentum is different in both cases.
Answer:
N₂ = 19 turns
Explanation:
A transform is a system with two different windings where the variation of the magnetic beam is the same, if there are no losses in the system we can use Faraday's law
V₁ = -N₁
v₂ = - N₂ \frac{d \Phi_B }{dt}
in this case we look for the number of turns in the second winding
N₂2 =
calculate us
N₂ = 360 6.30/ 120
N₂ = 18.9 turn
The number of turns must be an integer
N₂ = 19 turns
