Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that frequency = 1 MHz
speed of electromagnetic wave is same as speed of light
So the wavelength is given as
Part b)
As we know the relation between electric field and magnetic field
Part c)
Intensity of wave is given as
Pressure is defined as ratio of intensity and speed
KE=1/2mv^2
KE=1/2 x 5kg x (10m/s)^2
KE= 2.5kg x 100m^2/s^2
KE= 250 J
Power is the rate at which work is done (2nd option)
Yes, but not by much, unless the asteroid has a very large mass.
Momentum is proportional to mass times velocity
