By a positive test charge.
Answer:
Mass, m = 0.06 kg
Explanation:
It is given that,
Heat absorbed by copper object is 1386 J
Initial temperature,
Final temperature,
Specific heat of copper, c = 385 J/kg C
We need to find the mass of the copper. The formula of specific heat is given by :
m is mass of copper
So, the mass of the copper is 0.06 kg.
I believe the answer is a) 15 joules
Answer:
