If a 2 kg ball is traveling at a speed of 4 m/s, what is its kinetic energy?
MariettaO [177]

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.

2. Describe the functions of the SRP.
loris [4]

Single Recognition Particle (SRP) RNA is necessary for the targeting of proteins to the prokaryotic plasma membrane or to the eukaryotic endoplasmic reticulum membrane. Its job is to bind to the signal peptide of the membrane or secretory proteins coming from the ribosome at which time it forms a ribosome-nascent chain (RNC)-SRP complex.

SRP plays an important role in understsnding bacterial physiology, emphasizing the importance of proper membrane protein biogenesis, and demonstrates the ability of time-resolved quantitative proteomic analysis to provide new biological insights.
