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.
A physical property is an aspect of matter that can be observed or measured without changing it. A chemical property may only be observed by changing the chemical identity of a substance.
B.) Adenine because Dictated by specific hydrogen bonding patterns, Watson-Crick base pairs (guanine-cytosine and adenine-thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence.
