1. calculate the area of a conducting material with a temperature of 25degree conducting a heat quantity of 142kcal/hr and later reduced to a temperature of 15 degree. 2. The area of the conducting material is 152metre square with a proportionality constant. If the area given is 152 metre square, calculate the material using the above parameters​

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
