Answer:
Explanation:
PE = mgh where m is mass, g is the pull of gravity, and h is the height to which the object can possibly fall.
PE = 3.0(-9.8)(-12.4) so
PE = 360 J, rounded to the correct number of sig figs.
M*g*h
G is the gravity which is usually a fixed number (10)

Answer:
49.12 °C
Explanation:
= mass of gold sheet = 12 g
= specific heat of gold = 0.129 J/g°C
= initial temperature of gold sheet = 15 °C
= mass of iron sheet = 20 g
= specific heat of iron = 0.449 J/g°C
= initial temperature of iron sheet = 55 °C
= Final equilibrium temperature
Using conservation of heat
