The answer is D. As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases.
Answer:
Explanation:
1. Find the equation of eht maximal friction force:
The maximal friction force is given by the equation 
, where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.
2. Replace values in the equation to find the answer:
What you know:
Vi=0m/s
Vf=143.8m/s
A=-9.8m/s
d=???
Use the equation Vf^2=Vi^2+2A(d)
Rearrange to isolate d: d=Vf^2/2A
d=(143.8)^2/2(-9.8)
d=20678.4/-19.6
d=-1055m
The tank was released from a height of 1055m
Well the volcanos come from the lower crust and moves up with changes the climate
Answer:
Explanation:
I would have been an anti-federalist. They favored a weak central government because they related it to the British tyranny. Federalists believed in a strong central government, almost controlling. I would not have respected this type of government.
