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?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
