The input force will increase too because the more the ramp is increasing the more force is being put on the object going down the ramp... hope this helps ^-^
Answer: Gravity
Explanation: Gravity is pulling down on the ball, making it stay on the floor
To solve this problem it is necessary to apply the concepts related to the conservation of energy and heat transferred in a body.
By definition we know that the heat lost must be equal to the heat gained, ie

Where,
Q = Heat exchange
The heat exchange is defined as

Where,
Specific heat
m = mass
Change in Temperature
Therefore replacing we have that


Replacing with our values we have that




Therefore the highest possible temperature of the spoon when you finally take it out of the cup is 75.24°C
