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 stronger the wind, the larger the particles that are carried away. Erosion is the action of surface processes like wind flow and water flow that carries rocks, soil and dissolved particles from one point to another.</span><span>

Answer:
Explanation:
There are three known mechanisms of lateral gene transfer:
- Transformation
- Transduction
- Conjugation
