A person lies on a platform which has a scale under both ends. imagine the scale on the left reads 575 n and the scale on the right reads 280 n. when the person gets off the platform, both scales read 70.0 n.

If your life was a musical, what would the marquee say?

A spacecraft in outer space increases velocity by firing its rockets. How can hot gases escaping from its rockets change the velocity of the craft when there is nothing in space for the gases to push against?

If you've ever touched a traditional-style lightbulb, you probably noticed that they can get very hot.

Block 1 and Block 2 have the same mass, m, and are released from the top of two inclined planes of the same height making 30 degree and 60 degree angles with the horizontal direction, respectively.

Water waves change direction when they encounter water of different depths and begin to move at different wave speeds. This is called A. reflection B. constructive interference C. the Doppler effect D. refraction

Along with an alpha particle what other product is produced in the alpha decay of americium-241

What does Newton's second law of motion say

Two sinusoidal waves are moving through a medium in the positive x-direction, both having amplitudes of 7.00 cm, a wave number of k=3.00m-1, an angular frequency of ω=2.50s-1, and a period of 6.00 s, but one has a phase shift of an angle ϕ=π12rad.
