Answer:
mass of hot water must be 97.80
Explanation:
Answer:
Velocity
Explanation:
the speed of something in a given direction
Given :
A bicycle racer rides from a starting marker to a turnaround marker at 10 m/s.
She then rides back along the same route from the turnaround marker to the starting marker at 25 m/s.
To Find :
Her average speed for the whole race.
Solution :
We know, average velocity is given by :

Therefore, average speed for the whole race is given by 17.5 m/s.
It <span>states that the force F needed to extend or compress a spring by some distance X is proportional to that distance.
For elastic materials, they extend more in same amount of force, (as they are directly proportional), due to it's elastic nature (presence of large deforming force)
