Answer:
It depends on the product of their mass and velocity
Explanation:
The momentum of a moving object is defined as the product of its mass and its moving velocity. So a same object would have larger momentum it's traveling faster, or gets heavier, and vice versa. In our case we don't have the exact value of speed and mass of both objects so we can't say which one has a greater momentum.
Answer:
a) the velocity increases then decreases.
Answer: Option (B) is the correct answer.
Explanation:
As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.
But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.
As the boiling point of water is
so the temperature ceases to change from
to
.
Therefore, we can conclude that when heating water, during
to
temperature range the temperature will cease to change for some time.
