The blue mass in the image is 10kg. The red mass in the image is 10kg.

The blue mass is currently 4 meters away from the red mass.

If we change each mass to 20kg, what will happen to the gravitational force each mass puts on the other?? You have to pick a answer through A, B,C! The force of gravity will increase as the masses increase.

The force of gravity will not change as the masses increase.

The force of gravity will decrease as the masses increase.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

Which type of wave can travel without a medium

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
