Answer:
The metal will have changed temperature more than the water.
Explanation:
As we know that when two objects are mixed at different temperature then due to heat exchange between the two they both reach to same final temperature
This is known as thermal equilibrium
So here we have
Heat given by metal = heat absorbed by water
so we have
since mass of metal is same as that of water
so we have
so here we know that
so temperature change in water must be smaller than that of metal
We have that The ratio U1/U2 of their potential energies due to their interactions with Q is
From the question we are told that
Question 1
Charge q1 is distance r from a positive point charge Q.
Question 2
Charge q2=q1/3 is distance 2r from Q.
Charge q1 is distance s from the negative plate of a parallel-plate capacitor.
Charge q2=q1/3 is distance 2s from the negative plate.
Generally the equation for the potential energy is mathematically given as
Therefore
The Equations of U1 and U2 is
For U1
For U2
Since
U is a function of q and q2=q1/3
Therefore
For Question 2
For U1
Therefore
