<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>
f' = frequency observed by the police car after sound reflected from the vehicle and comes back to police car = 1250 Hz
f = frequency emitted by the police car = 1200 Hz
V = speed of sound = 340 m/s
v = speed of vehicle = ?
frequency observed by the police car is given as
f' = f (V + v)/(V - v)
inserting the values in the above equation
1250 = 1200 (340 + v)/(340 - v)
v = 6.9 m/s
<span>It is convection currents that carry thermal energy from warmer places to cooler places. The process operates upon planetary scales, as suggested by the question, but also operates on more local scales such as in your own house. For example, if there is a heater within a single room within your house, convection will drive heat energy to adjacent colder rooms. </span>
Answer:
Acceleration due to gravity will be 
Explanation:
We have given gauge pressure P = 3.8 atm = 3.8×101325 = 385035 Pa
Depth h = 24.3 m
Density 
We have find the acceleration due to gravity at the surface of planet
We know that pressure is given by
So 
Acceleration due to gravity will be
19,600 Newtons (about 4,400 pounds).
On Earth only.
Different in other places.
