Answer:
Wavelength of electromagnetic wave will be 5.281 m
Explanation:
We have given frequency of electromagnetic wave is 
Velocity of electromagnetic wave is 
We have to fond the wavelength of the electromagnetic wave
We know that velocity of electromagnetic eave is given by
, here
is wavelength and f is frequency
So 
Wavelength of electromagnetic wave will be 5.281 m
Answer:0.46
Explanation:
Given

------------1
distance traveled along the slope 



substitute in 1




Answer:
proton and neutrons
Explanation:
electron has negligible mass
Answer:
c)wind
Explanation:
Wind from the given choices will have the greatest amount of kinetic energy.
Kinetic energy is the energy due to motion of a body. It is different from the energy at rest in a body.
- Wind is air in motion.
- Wind energy is a form of kinetic energy in motion.
A book on a table, a slice of pizza and a person at the top of the stairs are all at rest and will possess potential energy.
