Two laser beams with wavelengths λ1-606 nm and 42-565 nm are aimed at the same point. The electric field from each lascr in the y-direction bchaves as the function, E, y(x, t) = A(sin(2TAt-20x/h) for-1 or 2, and they propagate at a speed of light. Both fields have the same amplitude, A = 1 N/C Randomized Variables Ay = 606 nm λ2 = 565 nm Find the value of the total electric field in the y-direction Ey, in newtons per coulomb, at a time of exactly one femtosecond (10^-15 s) if the position the lasers is aimed at is exactly 100 nm away from each laser.

Aheat engine running backward is called a refrigerator if its purpose is to extract heat from a cold reservoir. the same engine running backward is called a heat pump if its purpose is to exhaust warm air into the hot reservoir. heat pumps are widely used for home heating. you can think of a heat pump as a refrigerator that is cooling the already cold outdoors and, with its exhaust heat qh, warming the indoors. perhaps this seems a little silly, but consider the following. electricity can be directly used to heat a home by passing an electric current through a heating coil. this is a direct, 100% conversion of work to heat. that is, 19.0 \rm kw of electric power (generated by doing work at the rate 19.0 kj/s at the power plant) produces heat energy inside the home at a rate of 19.0 kj/s. suppose that the neighbor's home has a heat pump with a coefficient of performance of 4.00, a realistic value. note: with a refrigerator, "what you get" is heat removed. but with a heat pump, "what you get" is heat delivered. so the coefficient of performance of a heat pump is k=qh/win. an average price for electricity is about 40 mj per dollar. a furnace or heat pump will run typically 200 hours per month during the winter. what does one month's heating cost in the home with a 16.0 kw electric heater? what does one month's heating cost in the home of a neighbor who uses a heat pump to provide the same amount of heating?
