The change in the internal energy of the ideal gas is determined as -28 J.
<h3>
Work done on the gas</h3>
The work done on the ideal gas is calculated as follows;
w = -PΔV
w = -1.5 x 10⁵(0.0006 - 0.0002)
w = -60 J
<h3>Change in the internal energy of the gas</h3>
ΔU = w + q
ΔU = -60J + 32 J
ΔU = -28 J
Thus, the change in the internal energy of the ideal gas is determined as -28 J.

Answer:
The total charge Q of the sphere is .
Explanation:
Given that,
Radius = 5 cm
Charge density
We need to calculate the total charge Q of the sphere
Using formula of charge
Where, = charge density
V = volume
Put the value into the formula
Put the value into the formula
Hence, The total charge Q of the sphere is .
- Mass=m=142kg
- Acceleration=a=30m/s
- Force=F
Using Newton's second law
Answer:
1) Lightning, you see the lightning first and then hear the thunder.
2)When a person far away from you hits a ball with a bat, you can see them striking the ball first and then you will hear the sound of ball striking against the bat.
