Counter clockwise torque is 360Nm.
Clockwise torque is 240Nm.
40 * 9 = 360
80 * 3 = 240
The correct answer to the question is : 
EXPLANATION :
As per the question, the specific heat of gold is given as c = 
The heat given to the gold dQ = 195 J
The mass of the gold is given as m = 15 gram.
We are asked to calculate the change in temperature.
Let the change in temperature is dT.
We know that dQ = mcdT

[ANS]
Hence, the change in temperature is 100 degree celsius.
Ok so I’m pretty sure the answer would be 2 because the mass of the rock would have the same mass on Earth as it has on the moon. Also the Density of a solid object remains constant meaning it doesn’t change. But the weight would change because the Earths gravitational pull is more than that of the moon. I hope this helped!
