In an engine, an almost ideal gas is compressed adiabatically to half its volume. In doing so, 2820 J of work is done on the gas
1 answer:
Answer:
- Energy increases
Explanation:
From the question we are told that
Work done
a)Generally the heat flow for an adiabatic process is 0 (zero)
b)Generally Change in internal energy of gas is mathematically given by
Since
Therefore
Giving
c)With increases in internal energy brings increase in temperature
Therefore
Energy increases

What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3 = 55.0 nC placed between q1 and q2 at x3 = -1.220 m ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures.
Answer:
The net force exerted on the third charge is
Explanation:
From the question we are told that
The third charge is
The position of the third charge is
The first charge is
The position of the first charge is
The second charge is
The position of the second charge is
The distance between the first and the third charge is
The force exerted on the third charge by the first is
Where k is the coulomb's constant with a value
substituting values
The distance between the second and the third charge is
The force exerted on the third charge by the first is mathematically evaluated as
substituting values
The net force is
substituting values
