Identify the relationship between kinetic energy and gravitational potential energy for the cyclist at each position
1 answer:
Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.

B i think that the answer so
Given :
The temperature of 10 kg of a substance rises by 55oC when heated.
To Find :
The temperature rise when 22 kg of the substance is heated with the same quantity of heat.
Solution :
We know, change in temperature when heat is given to object is given by :
It is given that same amount of heat is given in both the cases also the substance is same.
So,
Hence, this is the required solution.
Answer:
The work done by gravity is 784 J.
Explanation:
Given:
Mass of the block is,
Height to which it is raised is,
Acceleration due to gravity is,
Now, work done by gravity is equal to the product of force of gravity and the distance moved in the direction of gravity. So,
Force of gravity is given as the product of mass and acceleration due to gravity.
. Now,
Therefore, the work done by gravity is 784 J.
