The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. to see just how rapidly the windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.0-m2 window that is 0.635 cm thick (1/4 in) if the temperatures of the inner and outer surfaces are 5.0ºc and −10.0ºc , respectively. this rapid rate will not be maintained—the inner surface will cool, and even result in frost formation.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in the collision? explain why or why not
