Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
<u></u>
<h3>What is the frequency?</h3>
Frequency is defined as the number of repetitions of a wave occurring waves in 1 second. Its unit is Hz. Frequency is given by the formula as,
A moving car is targeted by radio waves sent from a radar gun by a police officer standing still.
The radio waves reflected off the vehicle and picked up by the radar gun have a greater frequency than the radio waves that were transmitted.
A stationary police officer directs radio waves emitted by a radar gun at a vehicle moving toward the officer.
Compared to the emitted radio waves, the radio waves reflected from the vehicle and received by the radar gun have a<u> higher frequency.</u>
Hence the higher frequency is the correct answer for blanks.

Answer:
Carbon disulfide soryy if im wrong\
Explanation:
Answer: zero.
Justification:
The downward velocity of the sky diver just before starting to fall is zero, assuming that the helicopter is not moving but just hovering.
Before starting to fall, the velocity of the skydiver is the same of the helicopter, which is zero. It is only, once she jumps out of the helicopter that her weight is not supported by the helicopter and so the gravitational force of the Earth attracts the skydiver and she starts to gain velocity at a rate equal to g (around 9.81 m/s²).
Answer:
W = 170.62 N
Explanation:
The given question is, "calculate the weight of a person traveling to the moon whose mass is 105 kg".
We need to find the weight of a person on the Moon.
The weight of an object is given by :
W = mg
Where
g is acceleration due to gravity on Moon, g = 1.625 m/s2
W = 105 kg × 1.625 m/s²
W = 170.62 N
Hence, the weight of the person is 170.62 N.
