Answer:
Frequency of gamma rays is more than microwave.
Explanation:
The number of vibrations per unit time is called frequency of a wave. The SI unit of frequency is Hertz. It is equal to .
The frequency of gamma rays is of the order of . The frequency of microwave is of the order of
.
It is clear that gamma rays have more frequency that of the microwave.
Answer:
0.026 V
Explanation:
Given that,
Inductance of the coil, L = 6 mH
The current changes from 0.2 A to 1.5 A in a time interval of 0.3 s
We need to find the magnitude of the average induced emf in the coil during this time interval. The formula for the induced emf is given by :
So, the magnitude of induced emf is 0.026 volts.
B i think that the answer so
