One is the best choice for an answer.
<u>Answer:</u>
Work done done by a system on its environment is W=40 Joules
<u>Explanation:</u>
<u>Given:</u>
Ideal gas is maintained at a constant pressure 
Change in Volume 
<u>To find:</u>
Work done by a system during an Isobaric Process
<u>Solution:</u>
In a Isobaric Process, constant pressure is maintained, 
According to the formula,
work done 
Substitute the values of pressure and change in volume in the above formula,


<u>Result:</u>
Work done done by a system W= -40 Joules
Answer:
98 N
Explanation:
Weight is mass times acceleration due to gravity. Assuming the ball is near the surface of the earth, g = 9.8 m/s².
W = mg
W = (10 kg) (9.8 m/s²)
W = 98 N
