Answer:
primary voltage/secondary voltage = number of turns on primary coil/number of turns on secondary coil
V1/V2= N1/N2
1.5/5 = 150/N2
0.3 = 150/N2
N2= 150/0.3
N2 = 500
i d k I'm right or wrong but i tried.....lemme know if it's correct!!
That's not a good idea. You don't want to connect batteries with different voltages in parallel. What happens is large currents among the batteries themselves, and some of the batteries quickly die.
When the batteries are connected in SERIES, they behave as a single battery whose voltage is the sum of their individual voltages.
Answer:
Explanation:
For destructive interference , the condition is
2μt = nλ
2μt = n x 678
For constructive interference , the condition is
2μt = (2n+1)λ₁ /2
n x 678 = (2n+1)λ₁ /2
λ₁ = 1356 n / ( 2n + 1 )
λ₁ = 1356 / ( 2 + 1/n )
For longest wavelength , denominator should be smallest or n should be largest . The longest value of n is infinity so
λ₁ = 1356 / 2
= 678 nm .
Answer:
Bill's motor
Explanation:
Bill's motor lifts a box 0.39 metres in 2 seconds.
Nageen's motor lifts the same box 0.35 metres in 2 seconds.
Power = Work done/time
or
Power of bill's motor,
Power of Nageen's motor,
So, Bill's motor applied more power to the box.
