His is a step down transformer since n(primary) is greater than n(seconcary). You relate the input voltage with the ouput voltage with the following equation:
<span>Vout = n2/n1*Vin (n2/n1 is essentially your 'transfer function' that dictates what a specified input would produce) </span>
<span>Solving the equation: </span>
<span>Vin = Vout*n1/n2 = (320V)*(600/300) = 640 V </span>
<span>This is checked by seeing if Vin is greater than Vout, which it is for a step down transformer.</span>
Yes you are correct...I dont think you need to do this? You are getting them all right but now your just wasting points..
But anyways you are correct. ♡♡
Infra-red radiation has a slightly longer wavelength than red light ...
the longest wavelength that is visible to the human eye.
Although infrared can't be detected by the eye, we do have other
receptors that CAN detect it. They are some of the nerve endings
in our skin. When infrared radiation hits these, it produces the feeling
of warmth. Infrared radiation carries heat energy.
A person runs up 40 stairs and then come down 10 steps
So total stairs upwards is given as
now here we will have total height reached
Now total energy used or mechanical work done is
Now the mechanical power is given as
