Physics help needed with equations in photo If the specific heat capacity of the a certain metal is found to be a function of temperature c(T) = a + bT, where a = 0.25°J/kg oC and b = .08 J/kg °C^2, what is the energy, Q, required to raise the temperature of the 1 kg of metal from 20 oC to 60 oC?

Agroup of monkeys is trying to cross the river in a rowboat. the maximum buoyant force on the rowboat is 2,000 n. the weight of the rowboat is 1,000 n. each monkey has a weight of 150 n. how many monkeys can safely cross in the rowboat at one time? explain your reasoning, including any calculations you used to find the answer.
