Answer : The correct option is, (d) 
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of copper = 
= specific heat of water = 
= mass of copper = 120 g
= mass of water = 300 g
= final temperature of mixture = 
= initial temperature of copper = ?
= initial temperature of water =
Now put all the given values in the above formula, we get:


Therefore, the temperature of the kiln was, 
The potential difference between the plates will be 1552 Volts.
<h3>What is a potential difference?</h3>
Voltage, or the difference in electric potential between two points, is defined as the amount of labor per unit of charge needed to move a test charge between the two points.
Given that a 3.7-f capacitor that stores sufficient energy to operate a 75.0-w
The potential difference will be calculated by the formula below:-
Q = I t
Where I = charge / time
Q = V * C
V C = I t
V = I t / C
V = 75 C/s x 60 sec / 2.9 faraday
V = 1552 Volts

Answer:
Yes.
Explanation:
Rocket can propel itself in vacuum because the thrust is provided as a reaction to the the gases coming out of rocket, which have nothing to do with vacuum.
Answer:
First Dot That is located on Earth.
Explanation:
Due to Earth's gravity being greater than the moon's on earth there is more gravitational force pulling down on the spacecraft.
