A charge of +5.0 x 10-6 C is situated 0.2 meters away from another isolated charge of -3.0 x 10-6 C. What is the magnitude of the electric force that these charges exert on each other? Is this a repulsive or attractive force?

Which of the following would not be taken into consideration when describing the quality of a sound

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.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
