Answer:
The answer is C.move forward rapidly until stopped.
Explanation:
50 miles an hour is a very high speed. The momentum transfer to the car at stop light will move the car forward rapidly until its brake is able to stop it.
Answer:
Divergent - This type of evolution often occurs when closely related species diversify to new habitats. On a large scale, divergent evolution is responsible for the creation of the current diversity of life on earth from the first living cells. On a smaller scale, it is responsible for the evolution of humans and apes from a common primate ancestor.
Convergent - Convergent evolution causes difficulties in fields of study such as comparative anatomy. Convergent evolution takes place when species of different ancestry begin to share analogous traits because of a shared environment or other selection pressure. For example, whales and fish have some similar characteristics since both had to evolve methods of moving through the same medium: water.
Parallel evolution - Parallel evolution occurs when two species evolve independently of each other, maintaining the same level of similarity. Parallel evolution usually occurs between unrelated species that do not occupy the same or similar niches in a given habitat.
Answer:All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.Explanation:
Answer:
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
Explanation:
let speed be v
at top of hill
mg-N = mv^2/R ( N=0 at the top of the hill)
==> mg=mv^2/R
at bottom
N-mg=mv^2/R
therefore,
N = 2mg = 2*77.8*9.81= 1520.55 N
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
