They are prokaryotic cells....
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.
Answer:
Star-shaped.
Explanation:
Neurons are the nerve cell that acts as the basic structural unit of the nervous system. Neurons helps in the transmission of nerve impulse and transmit the signal into different parts of the body.
There are basically four types of microscopic neuron : unipolar, bipolar, multipolar and pseuounipolar neuron. Star-shaped neurons are not found in the microscopic description of neuron.
Thus, the correct answer is option (a).
