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>
Approximately 0.4373 seconds
Speed of sound at 20 degree C is roughly 343 meters/second
Speed of light = 3x10^8 or 300,000,000 meters/second
at 150.0 feet away you set it up as:
150.0/343 - 150/3x10^8
150.0/343 = 0.43731778
150/3x10^8 = 5x10^-7 or 0.0000005
Subtract 0.43731778 - 0.0000005
Answer is 0.43731728
Rounding would be approx. 0.4373

Answer:
Induced
Permanent
Transient
Explanation:
Induced: occurs when a molecule that has a permanent dipole repels another one's molecule's electrons, inducing the one that has a dipole moment in that molecule.
Permanent: occurs when two atoms in a molecule possess a substantially different electronegativity. i.e one atom attracts electrons more than another atom and males it more negative, while the other atom turns more positive.
Transient dipole: induces a dipole in the neighbouring molecule, and then interacts with the original transient dipole.
