Answer: 292.95 J
Explanation:
change in internal energy= Heat transfer - work done
ΔU =Q -PΔV
Here, Q = 0 as there is no heat transfer.
P =2.00 atm = 2.00 × 101235 Pa = 202470 Pa
ΔV = final volume - initial volume = 0.8 V -V = -0.2 V 
where V is the initial volume.
Volume of a spherical ball, 
r = d/2 = 23.9 cm / 2 = 0.12 m 


Hence, internal energy would change by 292.95 J.

Answer:
135 m
Explanation:
Speed = 45 m/s, time = 3 second
The formula for the distance is given by 
Distance = speed x time = 45 x 3 = 135 m
 
        
             
        
        
        
As it is pushed deeper, the buoyant force on the jar will decrease. The correct option is B 
<h3>What is buoyant force ?</h3>
The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force. Upthrust is another name for this upward thrust. A body submerged partially or completely in a fluid appears to shed weight, or to be lighter, due to the buoyant force.
The fluid under which an object is submerged exerts pressure, which is what generates the buoyancy force. Because a fluid's pressure rises with depth, the buoyancy force is always upward.
