Answer:
quantity A is mass and quantity B is wright
Answer:
The number of turns in the secondary coil is 4145 turns
Explanation:
Given;
the induced emf on the primary coil,
= 95 V
the induced emf on the secondary coil,
= 875 V
the number of turns in the primary coil,
= 450 turns
the number of turns in the secondary coil,
= ?
The number of turns in the secondary coil is calculated as;


Therefore, the number of turns in the secondary coil is 4145 turns.
Answer:
6.8 s
Explanation:
Let's say the west end of the field is position 0 m and the east end of the field is position 250 m.
The position of kitten A is:
x = 0 + 25 t
And the position of kitten B is:
x = 250 - 12 t
The kittens collide when they have the same position:
25 t = 250 - 12 t
37 t = 250
t ≈ 6.8 s
Answer: The magnitude of the velocity = 2/5 m/s
Explanation:
In this question, the magnitude of the velocity is the product of the magnitude of the displacement vector and the magnitude of the component of the velocity that acts in the direction of displacement.
This will be a scalar projection of V onto X
