PLS HELP ILL MARK BRAINLIEST A child is throwing stones at the center of a pool and would like to find the travelling speed of waves in water. Write an experimental design where the child can calculate the speed of wave.
Hint: Pool floor is built with foot long tiles.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

The mini-refrigerator fire was most likely caused by what type of wiring?

More solar radiation is absorbed by earth’s surface than by
