The maximum velocity she can reach when she skis to the bottom of the slope is
meters/second.
use pe = m × g × h, g = 9.8 m/s2, and . ignore air resistance and friction.

The height of the second hill is about 41.9 meters.

Explanation:

The car has 349,300 joules of energy at the top of the second hill. The mass of the car is 850 kilograms.

Plug the values for PE, m, and g into the formula, and solve for h:

349,300 = 850 × 9.8 × h

so h=349,300/850*9.8

h=41.9

answer: that would be cheating

explanation:

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
