Answer:
The electric field is 
Explanation:
From the question we are told that
The peak magnitude of the magnetic field is 
Generally the peak magnitude of the electric field is mathematically represented as
Where c is the speed of light with value 
So
Answer:Geography, Earth Science, Astronomy
Rotation describes the circular motion of an object around its center.
Explanation:
Answer:
0.003333 s to 0.000125s or from 3.33ms to 0.125ms wher m is for milli
1.1m to 0.04125 m
Explanation:
T= 1/f=
if f= 300Hz then T = 1/300 =0.003333 s
if f= 8000 then T= 1/8000 = 0.000125s
now v=f×wave length
or wavelength = speed/ frequency
when f = 300 Hz
wavelength = 330/300=1.1 m
wavelength = 330/8000 = 0.04125m
note : i have taken speed of sound as 330 m/s you can take any value given in between 330m/s to 340m/s
Answer:
c. √2T
Explanation:
The period of a simple pendulum is given by;
Thus, the the new period will be √2T
Answer:
0.2854
Explanation:
The Energy stored in coil is given by
U=
L
U=0.565Uo
Apply log: both sides we get
