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

Dmitry_Shevchenko [17]

Answer:

$Q=0$
$U=2820$
Energy increases

Explanation:

From the question we are told that

Work done $W=2820$

a)Generally the heat flow for an adiabatic process is 0 (zero)

$Q= U + W =>0$

$Q=0$

b)Generally Change in internal energy of gas is mathematically given by

Since $W=-2820J$

Therefore

$U=2820$

Giving

$Q= 2820 -2820$

$Q=O$

c)With increases in internal energy brings increase in temperature

Therefore

Energy increases

slava [35]

Answer:

The horizontal distance is 136.6 m.

Explanation:

Given that,

Initial speed = 38 m/s

Angle = 34°

Suppose, Calculate the horizontal distance $x_{max}$ in meters the ball has traveled when it returns to ground level.
