Explanation:
Here we can say that the momentum of the system will remain conserved
As here we can see that there is no external force in horizontal direction
so here we can say that
As the person in front throw the ball towards back the canoe will start moving forward direction so that momentum of the system will remain conserved
now after this we can say momentum of ball + canoe + two friends = 0 always
now when the person at the back of the canoe will catch the ball then again due to the concept of momentum conservation we can say that the whole system will again comes to rest
<em>so the canoe will become at rest after the person at the back will catch the ball</em>
Answer:
The new volume will be 60 liters, so the answer is e) None of these
Explanation:
Charles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly.
In other words, the Law of Charles establishes that the volume is directly proportional to the temperature of the gas: If the temperature increases, the volume of the gas increases and if instead the temperature of the gas decreases, the volume decreases.
This is mathematically represented by the quotient that exists between volume and temperature, which will have the same value:
Assuming that you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment, if you vary the volume of gas to a new value V2, then the temperature will change to T2, and it will be true:
In this case:
- V1= 20 L
- T1=100 K
- V2= ?
- T2=300 K
Replacing:
Solving:
V2= 60 L
<u><em>The new volume will be 60 liters, so the answer is e) None of these</em></u>
