Pounding a nail into wood makes the nail warmer. Consider a 6-gg steel nail 6 cmcm long and a hammer that exerts an average force of 490 NN on the nail when it is being driven into a piece of wood. Find the change in the nail's temperature after it was pounded into the piece of wood completely. (Assume that the specific heat capacity of steel is 450 J/kg⋅∘CJ/kg⋅∘C.) I can't find the correct formula to solve this equation.

Dear Sir/ Madam, 1/ Pounding a nail into wood makes the nail warmer. Consider a 5-gram steel nail 6-cm long and a hammer that exerts an average force of 500-N on the nail when it is being driven into the wood. What is the increase in the nail’s temperature if the specific heat capacity of steel is 450 J/kgˑC° using this formula: Work is given by F X d, and temperature change as Q = cm ∆T. (Hint: convert the unites to more manageable amounts). 2/ Using the formula: Power = Current X Voltage, find the current drawn by a 1200-W hair dryer connected to 120V. 3/ Two point charges are separated by 6cm. The attractive force between them is 20 N. What is the force between them when they are separated by 12cm? (Hint: This involves relative distance only). 4/ Find the voltage change when an electric field does 12 J of work on a charge of 0.0001C. 5/ Find the voltage change when an electric field does 24 J of work on a charge of 0.0002C. 6/ If a red-hot nail is immersed in warm water, the…

Radioactive decay of granite and other rocks in Earth's interior provides sufficient energy to keep the interior molten, to heat lava, and to provide warmth to natural hot springs. This is due to the average release of about 0.03 J per kilogram each year. Find an increase in temperature for a thermally insulated chunk of granite that takes about 12.6 million years to change temperature. (Assume that the specific heat capacity cc of granite is 800 J/kg⋅C∘J/kg⋅C∘. Use the equation Q=cmΔTQ=cmΔT.)
