Answer:
- Option D is the correct answer.
Explanation:
It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.
KE = 1/2 mv²
KE = 1/2 × 2×(4)²
KE = 1/2 × 2×16
KE = 16 J
<u>Some information about Kinetic Energy</u>.
Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,
- KE = ½mv²
- It occurs due to the motion of the particle.
- If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.

The correct option is (D).
An amino group and carboxylic acid group are the most basic common components in all amino acids. While, R group in the amino acids always different (here R describes the alkyl group).
Organic substances having both amino and carboxylic acid functional groups are known as Amino acids. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature.
Amino acids perform a variety of processes in our body including muscular growth, delivering nutrition, prevent disease, and many more. A lack of certain amino acids can lead to a variety of health concerns, including lowered immunity, digestive disorders, depression, less mental alertness, slower child growth, etc.
There are total 20 amino acids, out of them 9 are essential amino acids means they are not synthesis by our body they must be taken outside from diet and nutrition.
