The centripetal acceleration of the race car is 40500 mi/hr^2.
This can be calculated as the square of the velocity v divided by the radius r of the circular track:
a = v^2 / r
Substituting the given values of velocity v = 135 mi/hr and radius r = 0.450 miles, the centripetal acceleration a of the car is therefore
a = (135 miles/hour)^2 / (0.450 miles)
= 40500 miles/hour^2.
Answer:
Stabilizing selection
Explanation:
Stabilizing selection is the most common form of natural selection that is not easy to notice in a population as the change is less drastic. It occurs when average or intermediate phenotypes of a trait in a population are favored, while the extreme phenotypes of that trait are not favored by the forces of natural selection. Over time, intermediate or non-extreme traits become more common in the population, while extreme traits become less common.
Answer:
Option (A).
Explanation:
The substance can exist in three different forms known as solid, liquid and gas. These forms of the substances are differentiated on the bases of the inter molecular distance, force of attraction and fluidity.
Gases nether have fixed volume nor the fixed shape and can change itself according to the place in which it is kept. The kinetic molecular theory of the gases states that the gases are always in the rapid and random motion. This is possible due to the presence of the least force of attraction among the particles of the gases.
Thus, the correct answer is option (A).
Answer:
A
Explanation:
The answer is A because they get their genetics from both parents, not just one
Answer: The invention of the powerful atomic force microscope has enabled scientists to study cells at an atomic level. This enables scientists to scrutinize viruses at their atomic level and influence them for delivery of innovative treatments
