A plucked guitar string produces a sound wave of frequency 440 Hz. (a) What is the wavelength of the sound wave (assume the speed of sound in air is 340 m/s)? (b) How much time elapses between the impacts of two adjacent compression on your eardrum?
How long is the bridge? Write down an equation for the bridge's height. And how far from the center of the bridge are two points if bridge's height at those points is 80 meters.
An 800-N man stands halfway up a 5 m long ladder of negligible weight. The base of the ladder is 3 m from the wall as shown. suppose that the wall-ladder contact is frictionless, wall pushes against the ladder with a force of what magnitude.
A 50 kg ballet dancer stands on her toes during a performance with four square inches (26.0 cm2) in contact with the floor. What is the pressure exerted by the floor over the area of contact (a) if the dancer is stationary and (b) if dancer is lea..
There are four coils of wire being used as electromagnets. They all have the equal size and are made up of the same material but have a different number of loops.
