A = change in velocity / change in time
in your case a = 0(final velocity)-30(initial velocity)/10
so, a = -30/10 = -3 m/s^2
I hope this helps you!
The relative pressure at this state is determined as 0.455.
<h3>Initial pressure of the ideal gas </h3>
The pressure of the ideal gas given rise to the relative pressure is calculated as follows;
R.P = P2/P1
P2 = P1(R.P)
P2 = 200 kPa x (3.482)
P2 = 696.4 kPa
<h3>New relative pressure</h3>
R.P = (P3)/(P2)
R.P = (320)/(696.4)
R.P = 0.455
Thus, the relative pressure at this state is determined as 0.455.

Answer:
33,333.3J/s
Explanation:
Energy expended which is the work done in Joule
=250,000J
Time taken to expend the energy =7.5s
Power =Unknown
Formula
Power = <u> </u><u> </u><u> </u><u> </u><u> </u><u>Work</u><u> </u><u> </u><u> </u>
Time
Hence, Power = <u>250,000J</u>
7.5s
Power = 33,333.3J/s
<span>A mountain top has very high altitude, but valley has very low altitude comparing to a mountain.
As we go high temperature decreases accordingly .That is 1.8 F decreases in 165 feet.
As mountain are very high , so their temperature are very less comparing to a valley.</span>
