The option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion
The correct answer choice is option c
In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.
<h3>What is energy?</h3>
Energy can simply be defined as the capacity of doing work.
Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.
The unit of energy joules.
Other examples of derived quantities just like energy too are:
- Volume
- Speed
- Acceleration
- Density.
- Upthrust
- Momentum
- Momentum
- Power
- Pressure
- Force
Below are some few forms of energy; these are:
- Kinetic energy
- Potential energy
- Mechanical energy
- Solar energy
- Light energy
- Chemical energy
So therefore, the option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion

Data:
F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²
We apply the data to the Resultant Force formula, we have:
4.0 kg

The mass of Copper electroplated is 68.76 g
<h3>What is electroplating?</h3>
The process of plating a metal onto another is known as electroplating.
It is often used to prevent corrosion of metal or for the decorative purposes
In this process, electric current is passed through an aqueous solution containing dissolved cations.
The dissolved cations are reduced developing a thin metal coating on the electrode.
At cathode,
Current, I = 14.5 A
Time, t = 4 hrs = 4×60×60 = 14400 sec
Charge, q = It = 14.5×14400= 208800 C
Copper metal deposited by 2×96487 C = 63.55 g
Copper metal deposited by 208800 C = 
= 68.76g
Hence, The mass of Copper electroplated is 68.76 g

Answer:
What procedure did you use to complete the lab?
→Procedures that needs to be considered to complete the lab are- a thorough knowledge of lab assignments, knowledge about safety equipment, reviewing the MSDS of chemicals for lab experiment etc.
<h3>Explanation:</h3>
To be lab prepared one must follow these procedures-
1. One should have the knowledge of lab assignments to make the lab experiment easier.
2. To be aware about safety equipment and their uses in lab, like- the location of fire extinguisher in lab.
3. To know the steps of experiments to be performed
4. To fill notebook of lab with information regarding the experiment
5. One should review the data sheets of chemicals material safety.
6. To put on all the necessary dressings to perform experiment.
7. To have complete understanding about the experiment disposals.
