Answer:

Explanation:
In that the gas thermometer is a constant volume, it is satisfied that:
How the boiling water is under regular atmospheric pressure, then

Thus


True the magnitude is the velocity of speed
Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model, 
Speed of the model, 
Mass of another model, 
Initial speed of another model, 
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :



V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
