1000/48 is 20.83 so the answer would be 20.83 meters/second
Answer: 1A
Explanation: for an ideal transformer, the relationship between number of turns and current is given below as
Ip/ Is = Ns/ Np
Where Ip = current in primary loop = 3A
Is = current in secondary loop =?
Np = number of turns in primary loop = n
Ns = number of turns in secondary loop = 3n
By substituting the parameters, we have that
3/Is = 3n/n
3/Is = 3
3 = 3 × Is
Is = 3/3 = 1A
Current in the secondary loop is 1A
Answer:
A police radar gun uses X-band microwave radiation at a frequency of 13.1 GHz. Microwaves travel at the speed of light, or 3x108 m/s. Since the frequency shift will be small for practical car speeds and difficult to detect, the shifted frequency is compared to the original frequency, and the resulting beat frequency is used to determine the speed of the car.
a.) If Michael is traveling at 29 m/s, what is the resulting beat frequency that the radar gun detects?
ANSWER: 2533 Hz
