Question 2: 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.

Mass and velocity are the 2 factors used to calculate kinetic energy. the equation for kinetic energy is (1/2)mv^2. hope this !

The correct answer is antinodes

The pressure on how fast or slow the car is going

The correct option is this: the sound waves from the two trombones have slightly different frequencies.from the question given above, we are told that the loudness of the sounds were increasing and decreasing, this is because the frequencies of the two sounds are different. the means that the number of waves that pass a fixed point in a given amount of time differ for both sounds.
