All electromagnetic waves travel at 3*10^8 ms⁻¹ , the equation for wave speed is v=wavelength*frequency. Therefore wavelength=v/f=3*10^8/600000000=0.5m
Answer:
Part a)
Part b)
Explanation:
Magnetic field due to outer solenoid inside it is given as
Now similarly we have
magnetic field due to inner solenoid on it axis is given as
Part a)
Now if a proton is revolving around the common axis of two solenoids
then we will have
Part b)
Now proton is revolving in the field of outer cylinder only
so again we have
A ph 1 Jxdjjdxkxkxkslxlxkxjbx
D. Increase In Density
This is because more buoyancy an object has, the more it increases in density.
