8) Granite has a specific heat of 800.00J/gºC. What mass of granite is needed to store 150,000.00J
of heat if the temperature of the granite is to be increased by 15.5°C?

Need answer ASAP

Explanation:

specific heat of granite  S = 800 J /g°C

increase in temperature = 15.5 °C .

mass  = m ( let )

Heat needed to raise temp  = mass x specific heat x rise in temperature

150,000 = m x 800 x 15.5

m = 12.096 g .

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
