Solar cells are given antireflection coatings to maximize

Nelson W 2022-10-02

Solar cells are given antireflection coatings to maximize their efficiency. Consider a silicon solar cell (n=3.50n = 3.50) coated with a layer of silicon dioxide (n=1.45n = 1.45).

 

What is the minimum coating thickness (but not zero) that will minimize the reflection at the wavelength of 704 nm nm where solar cells are most efficient?

An 80.0-kg skydiver jumps out of a balloon at an altitude of1000 m and opens the parachute at an altitude of 200 m. (a) Assuming that the total retarding force on the diver is constant at 50.0 N with the parachute closed and constant at 3600 N with the parachute open, what is the speed of the diver whenhe lands on the ground? (b) Do you think the skydiver will be injured? Explain. (c) At what height should the parachute be opened so that the final speed of the skydiver when he hits the ground is 5.00m/s? (d) How realistic is the assumption that the total retarding force is constant? Explain.

Energy is conventionally measured in Calories as well as in joules. One Calorie in nutrition is 1 kilocalorie, which we define as 1 kcal = 4186 J. Metabolizing 1 gram of fat can release 9.00 kcal.

A student decides to try to lose weight by exercising. She plans to run up and down the stairs in a football stadium as fast as she can and as many times as necessary. Is this in itself a practical way to lose weight?

To evaluate the program, suppose she runs up a flight of 74 steps, each 0.173 m high, in 58.8 s. For simplicity, ignore the energy she uses in coming down (which is small). Assume that a typical efficiency for human muscles is 20.0%. This means that when your body converts 100 J from metabolizing fat, 20 J goes into doing mechanical work (here, climbing stairs). The remainder goes into internal energy. Assume the student's mass is 52.8 kg.

How many times must she run the flight of stairs to lose 1 pound of fat? (1 lb = 0.454 kg)

 

What is her average power output, in watts and in horsepower, as she is running up the stairs? (1hp = 746 W)
