The frequency of the sound is 500
I believe it is D, although you may should learn about all four of these laws.
Answer:
See a tractor is more slow but has a greater force and a car is fast but has a slower force
Explanation:
so your answer is Tractors have more force then cars
Distance=20m
time=18s
Initial velocity=0m/s
Final velocity=10m/s
The equation we use to find average velocity is v=d/t (average velocity=distance/time)
V=20m/18s
V (average velocity)=1.11m/s
Answer: add 10 cm plus 200 mpa divided by 2 min then caculate that into 160 bars.
