<h2>Option C is the correct answer.</h2>

Explanation:

We have equation of motion v = u + at

Initial velocity, u = 18 m/s to east

Final velocity, v = 19 m/s to east

Acceleration, a = ?

Time, t = 5 s

Substituting

             v = u + at

             19 = 18 + a x 5

              1 = 5a

               a = 0.2 m/s²

Since the velocity direction is towards east, direction of acceleration is also towards east.

So acceleration is 0.2 m/s² towards east.

Option C is the correct answer.

What ia the law of convesation of energy​
Free_Kalibri [48]
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Cheetah mothers perform a number of different behaviors. They and their cubs stay in one place for only four days, moving on bef
Mekhanik [1.2K]

Answer:

Cheetah cubs are in danger from predators like lions and hyenas which can track their prey by scent and so the mother and her cubs leave an area when their scent is too strong so that they are not hunted and the cubs survive.

Mother Cheetahs also train their cubs to hunt so that they may get food for themselves which will ensure their survival as well thus showing that both of these practices can impact on reproductive success.
