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

Biology

MariettaO [177]3 years ago
6 0

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 hormone _______________ is released from the pancreas when blood glucose is elevated above a normal range.
Viktor [21]
<span>The hormone INSULIN is released from the pancreas when blood glucose is elevated above a normal range.

This hormone regulates your blood sugar level. When your blood glucose is elevated above a normal range, the insulin is released from the pancreas. It then attaches itself to the cells and signals them to absorb the excess sugar from the blood stream. 

If your blood sugar level is low, insulin signals the release of stored sugar to the blood stream to maintain the normal level of your blood glucose.</span>

Amenorrhea may occur among women at fat levels as high as:
Sophie [7]
The correct answer is "16%"

16% of body fat in women is considered as low as normal body fat levels in women normally ranges from 22% to 25%. In cases of low body fat levels (i.e. in athletic women), there will be relative amenorrhea because of the suppression of the follicle-stimulating hormone and the luteinizing hormone leading to a type of amenorrhea called athletic amenorrhea.

Do autotrophs need to carry out cellular respiration?
yawa3891 [41]
Plants do carry out cellular respiration
They use it to convert glucose, a product from photosynthesis, into ATP, the energy carrying molecule

Btw plants and animals carry out cellular respiration
ONLY PLANTS carry out photosynthesis because they make their own food but they still need to convert it into energy
