A rolling ball travels 7.3m in 3.7s. What was the velocity of the ball?

Biology
1 answer:
rjkz [21]3 years ago
5 0

Answer:

Velocity of rolling ball = 1.97 m/s (Approx.)

Explanation:

Given:

Distance travel by rolling ball = 7.3 meter

Time taken by rolling ball = 3.7 seconds

Find:

Velocity of rolling ball

Computation:

Velocity = Distance / Time

Velocity of rolling ball = Distance travel by rolling ball / Time taken by rolling ball

Velocity of rolling ball = 7.3 / .37

Velocity of rolling ball = 1.9729

Velocity of rolling ball = 1.97 m/s (Approx.)

hichkok12 [17]

Answer:

True

Explanation:

Conjuctiva is that thin transparent mucous membrane that covers both the anterior surface and the inner surface of the eyelid. Conjuctiva is an important component of the eye that keeps the inner surface of the eyelids and the front surface of the eye moist and lubricated. It also helps protect the eye from foreign particles and from infection.

The part of the conjunctiva that covers the eyelids and is reflected over the anterior surface of the eyeball is called the bulbar conjunctiva. The part that is found coating the inner surfaces of the eyelids is called the palpebral conjunctiva.

Why does synthetically produced RNase refold incorrectly if the reducing agent is removed before urea removal?
olya-2409 [2.1K]
<h2>Disulfide bonds interaction </h2>

Explanation:

  • The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
  • During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
  • The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
  • Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"

Please explain when you have smaller population does evolution happen faster
denis-greek [22]

Answer:

Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.
