Answer:
The wavelength of the radio wave will be 3.271 m
Explanation:
We have given frequency of the radio signal 
Speed of the light 
We have to find the wavelength of the radio signal
We know that wavelength is given by 
So the wavelength of the radio wave will be 3.271 m
Answer:
impact- equal
impulse- equal
momentum- equal
acceleration- the empty cart
The temperature of a gas is increased from 125 celsius inside a rigid container. The original pressure of a gas was 1.22atm, what will the pressure of a gas be after the temperature changes?
The velocity of the air relative to the runner is 5 m/s.
<h3>What is the relative velocity?</h3>
We must recall that velocity is a vector quantity and the relative velocity must be obtained vectorially. Thus we know that;
Velocity of the runner = 4m/s. due west
Velocity of the wind = 3m/s due south
The relative velocity is;
Vr = √(4)^2 + (3)^2
Vr = 5 m/s

Answer: The correct answer is (a).
Explanation:
The potential energy is due to the position of the object.
The kinetic energy is due to the motion of the object.
In the case of a basketball sitting on a shelf, the basketball posses the potential energy due to some height.
In the case of a dog running across a field, a dog has kinetic energy due to its motion.
In a case of a bowling ball rolling down a lane, there is kinetic energy due to the motion of the bowling ball.
In the case of a teenager riding their bike, there is kinetic energy due to the motion of the bike.
Therefore, the correct answer is (a).
