Part a)
As we know that

here we know that
P1 = 20 bar
V1 = 0.5 m^3
V2 = 2.75 m^3
from above equation


so final state pressure will be 2 bar
Part b)
now in order to find the work done

The centripetal force upon an object is expressed as
F = mv^2/r
So let's substitute the known values and calculate
F = mv^2/r
F = 1.0 kg * (5.0 m/s)^2 / 0.5 m
F = 1.0 kg * 25 m^2/s^2 / 0.5 m
F = 25 kg*m^2/s^2 / 0.5 m
F = 50 kg*m/s^2
F = 50 N
So the answer is 50 N which matches one of the available choices.</span>
The gravitational force exerted on the satellite is called the centrifugal force, the force keeping it orbiting to the planet. Its formula is F= mass times the square of the velocity all over the radius.Thus,
F = 2400 * 6670^2 * (1/8.92x10^6)
F = 11,970 N
I hope I was able to help you. Have a good day.
Answer:
<h2><em>V(water)= 237 mL=237×10^-6 m^3</em></h2><h2><em>ρ(water)=1000 kg/m^3</em></h2><h2><em>
m=</em><em>ρ×V=(1000)×(237×10^-6)</em></h2><h2><em>
m= 237×10^-3 = 0.237 kg</em></h2><h2><em>
m= 237 gram.</em></h2>
Answer:
A) 0.0 kJ
Explanation:
Change in the internal energy of the gas is a state function
which means it will not depends on the process but it will depends on the initial and final state
Also we know that internal energy is a function of temperature only
so here the process is given as isothermal process in which temperature will remain constant always
here we know that

now for isothermal process since temperature change is zero
so change in internal energy must be ZERO
