<span>The amount of energy required to raise the
temperature of 1 kilogram of a substance by 1 Kelvin is called the specific
heat. The answer is a. For example, water. Water has a specific heat of 4.18
Joules per kilogram per Kelvin. This means that in order for water to change from
one state to the other at one kelvin, it needs 4.18 Joules of energy per one
kilogram of water. But it does not apply to changes in phase, because the heat
added or removed during a phase change does not change the temperature of a
substance.</span>
It could be called COLLISION
An animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.
Different animals have different senses heightened, that lets them use different mechanisms to navigate. Some of the mechanism include remembering landmarks, solar navigation, star navigation, magnetoreception, olfaction, gravity receptors etc.
For example, a bird using landmark to navigate will find it hard to navigate in the same way again if the landmark has been changed. So it has to depend on other senses such as olfaction or magnetoreception to navigate.
Therefore, an animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.

Answer:
B. speed up
Explanation:
The acceleration of an object due to a body's gravity is:
g = GM / r²
where G is the universal constant of gravitation,
M is the mass of the body,
and r is the distance from the body.
As a planet approaches the sun, r decreases. As r decreases, g increases.
