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

Explanation:
Answer: 50m
Explanation:
Velocity is the Amount of Displacement an object makes, as Speed is the amount of Distance. As the problem is asking for displacement, find out how much he/she went in a straight line. He went from 10 - 60, so suptract, and get 50m.
Answer:1.8 hr
Explanation:
Given
mass of cargo=500,000 kg
initial speed
Frictional force=85 v
at t=0 engine is shut off so acquired speed is slowly decreasing
Integrating both sides
t=6462.425 s
t=1.8 hr
