Lucas has a cup of hot tea. its temperature is 80oc. to cool it off, lucas has put an ice cube in the tea. the temperature of the ice cube is 0oc. the cup of tea with the ice cube sits on a table, and the air around it is 25oc. which of the following correctly describes how heat will flow in this situation?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?

Which of the following are forms of phase changes a. freezing b. condensation c. heating d. exchanging
