A lead block of mass 2kg falls from a height h to the ground. The specific heat capacity of lead is 120J/kgk and the rise in temperature is 0.4°C. Calculate the height
Answer
Change Potential energy = change in heat of leat
"Mgh=MS\\Delta T"
"h=\\frac{S\\Delta T}{g}"
By putting the value
"h=\\frac{120\\times0.4}{9.8}=4.89m"
