Answer:
Digestion helps mammals eliminate bodily waste.
Explanation:
Humans are considered mammals and we use digestion to eliminate bodily waste. Digestion has three main functions. First digestion of food, second absorption of nutrients, and third elimination of solid waste. There are two processes that take place Mechanical digestion and chemical digestion. Mechanical digestion is the chewing and breaking down of food into smaller molecules, whereas chemical digestion is the breakdown of the smaller molecules into simpler nutrients that the body can absorb and use.
Answer:
Vaporation
Explanation:
In the vaporization or boiling, the passage of particles from the liquid state to the gaseous state occurs completely
Answer:
Correct Answer is positive force → balanced force → negative force
Explanation:
When Diego gives a big lift to the piano with the help of pulley system that time, initially piano moves upward so positive force acts on it.
Later, Piano stops, in this condition balanced force act on it since force applied by Diego is balanced by gravitational force of earth.
After some time piano starts falling in this condition negative force will act on the piano. In this condition, gravitational force will acts on piano in downward direction.
As per initial given conditions first we will find the initial potential energy of the feather
now we know that few amount of its initial energy is lost in form of frictional energy loss
so remaining energy will be less than the initial potential energy
So final answer would be
<u><em>A. KE < 0.0196 J</em></u>
