a transformer changes 95 v acorss the primary to 875 V acorss the secondary. If the primmary coil has 450 turns how many turns d
1 answer:
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.

The force between the two objects is 19.73 nN.
<u>Explanation: </u>
Any force acting between two objects tends to be directly proportional to the product of their masses and inversely proportional to the square of the distance between the two objects. And this kind of attraction force between two objects is termed as gravitational force.
So if we consider and
as the masses of both objects and let d be the distance of separation of two objects. Then the force between the two objects can be determined as below:
As gravitational constant ,
= 20 kg and
= 100 kg, while d = 2.6 m, then
Thus, we get finally,
As we know, nano denoted by letter 'n' equals to
So the force acting between two objects is 19.73 nN.
