Like they said the leopard seal will overpopulate and kill out all of the other animals. Because it would be at the top of the chain then without the killer whale. Therefore, since it is at the top of the chain it will overpopulate because it has nothing to eat/kill it so then they would eat the animals lower than them

Displacement: Consider a deer that runs from point A to point B. The distance the deer runs can be greater than the magnitude of

adoni [48]

Answer:

The given statement concerning distance and displacement is true.

Explanation:

If any point travels along any path between two points A and B the distance it travels is the length of the actual path it travels.

Mathematically the distance between two points is the algebraic sum of the infinitesimal distances that the particle travels.

Mathematically $S=\int |ds|$

Displacement by definition is the shortest distance between the initial and final positions of the particle and is given by the straight line joining the two points.

Since a line is the shortest path that exists between 2 points thus it will be always smaller than any other path connecting the 2 points hence will be smaller than the distance.

While as if the object travels along a straight line without changing it's direction the distance in that case equals the displacement.

72) What is the freezing point (°C) of a solution prepared by dissolving 11.3 g of Ca(NO3)2 (formula weight = 164 g/mol) in 115

Rina8888 [55]

Answer: The freezing point of solution is -3.34°C

Explanation:

Vant hoff factor for ionic solute is the number of ions that are present in a solution. The equation for the ionization of calcium nitrate follows:

$Ca(NO_3)_2(aq.)\rightarrow Ca^{2+}(aq.)+2NO_3^-(aq.)$
