Answer:
Explanation:
Let mass of bullet = m1 = 28g= 0.028 kg
mass of pendulum = m2 = 3.1 kg
Down wards because it’s right and right I need 20 letters
The formula to find the speed of a wave
speed = wavelength x frequency
speed and frequency are directly proportional so as one increases then the other one will increase as well. in this case as the frequency increases then the speed of the wave will also increase.
hope this helps :)
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
