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.
D. The osculations show a variable rate of motion. Hope this helps:)
Answer:
In constructive interference, a crest meets a crest or a trough meets a trough, resulting in a larger crest or trough.
In destructive interference, a crest meets a trough and results in cancellation hence a smaller disturbance than either of the two interacting waves.
Answer:
<u> Power = 9.75 ×10^8</u>
Explanation:
- Power is rate of change of energy.
- Here gravitational energy is transferred to kinetic energy of water at a definite rate.
For one second 650m^3 of water flows out down to 150m oh depth.
So, the energy at a height of 150m is transformed to kinetic energy.
for a second,
650m^3 of water flows down ⇒ (1000kg/m^3 × 650m^3) = 6.5×10^5kg of warer flos down.
The total gravitational potential energy stored in water is
= <u>mass of water × height× gravity</u>
= 6.5 ×10^5 × 150 × 10 = 9.75 ×10^8
As it is transformed in a second it is also equal to <u>Power.</u>
