Suppose you have a light spring stretched out and one end is attached to a wall. With this setup, you can move the free end in any of three directions (x, y, z). The spring lies along the z axis. Which type of wave do you create when you move the free end along the z axis?
Which type of wave do you create when you move the free end along the x axis?
Which type of wave do you create when you move the free end along the y axis?
CHoose one for each.
transverse
longitudinal

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.

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
