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.
Answer:
The fraction of kinetic energy lost in the collision is 0.25 .
Explanation:
We know , momentum will be conserved along x direction .
Therefore ,
Now , fraction lost in kinetic energy is :
Therefore , the fraction of kinetic energy lost in the collision is 0.25 .
A heat engine would be less efficient due to many factors
For instance, a heat engine is more efficient when it uses in cold weather because there is a greater temperature difference ( Carnot Efficient )
A heat engine could be less efficient because of friction
