Answer:
3600 kg m/s
Explanation:
Momentum can be calculate using the following formula:
p=m*v
where p is the momentum in kg m/s, m is the mass in kilograms, and v is the velocity in m/s.
We know the mass of the car is 800 kilograms and the car is traveling at 4.5 m/s. So, m=800 and v=4.5 Therefore, we can substitute 800 for m and 4.5 for v.
p=m*v
p=800*4.5
Multiply
p=3600
The momentum is 3600 kg m/s

I’m looking for the same thing lol
Explanation:
In electrical work, resistance is often represented by the Greek symbol <span>Ω. The correct option among all the options that are given in the question is the first option or option "a". It is actually a Greek Letter Omega and is written in upper case. I hope this is the answer you were looking for and it has helped you.</span>
The statement is false.
Pitch of a sound wave is the quantity that determines how high or low a sound is when it is perceived. A higher pitch corresponds to a higher frequency.
There could be another case, the Doppler's effect. the source or the observer might be moving towards the other. In such cases, the frequency of the sound wave does not change but it appears to be rising due to the motion.
From the calculations, the speed of sound in this case is 16.9 m/s.
<h3>What is an echo?</h3>
The term echo has to do with the reflection of sound waves. Sound is a mechanical wave.
we know that the speed of sound is obtained from;
V = 2x/t
x = distance covered
t = time taken
V = 2(500)/59
v = 16.9 m/s
The error in the experiment could come from;
- Lack of precise time measurement
- Error can also arise from the environment of the experiment
