The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.
The given parameters;
- time of fall of the first ball, t = 1 s
- time of fall of the second ball, t = 3 s
The distance traveled by each ball is calculated using the second equation of motion as shown below.
The distance traveled by the first ball is calculated as follows;
The distance traveled by the second ball is calculated as follows;
Thus, the second ball traveled a greater distance because it spent more time in motion.

Example of surface events are erosion and weathering. Erosion is the carrying of a particle from one place to the other and weathering is the breaking down of particles. These processes help in rock formation because this allows physical changes (grouping together or breaking down) on a certain substance. Subsurface events are those which happened underground such as the flow of underground water which subsequently allow the deposition of minerals, etc.

Answer:
A.
B.
C.
D.
Explanation:
Given:
- no. of moles of oxygen in the cylinder,
- initial pressure in the cylinder,
- initial temperature of the gas in the cylinder,
<em>According to the question the final volume becomes twice of the initial volume.</em>
<u>Using ideal gas law:</u>
A.
<u>Work done by the gas during the initial isobaric expansion:</u>
C.
<u>we have the specific heat capacity of oxygen at constant pressure as:</u>
Now we apply Charles Law:
<u>Now change in internal energy:</u>
B.
<u>Now heat added to the system:</u>
D.
Since during final cooling the process is isochoric (i.e. the volume does not changes). So,
