A flower basket is hung from the end of a uniform horizontal pole which projects from a wall, as shown. The pole is supported by a cable attached to a higher point on the wall:
The pole has a mass of 10.0 kg; the flower basket has a mass of 14.0 kg.
a By taking moments about the right hand end of the pole, determine the value of the
tension in the cable T. [5]
b The wall exerts a force R on the pole. Deduce the horizontal component of R.

Several processes form metal ore. match each process to its description. volcanic activity weathering hydrothermal energy rocks break down as they interact with air and water. arrowright density differences and other factors cause metals to concentrate in igneous rocks. arrowright seawater heats up from contact with hot rock, and metals dissolve in it. the water rises and contacts cooler water, causing metal ores to settle on the ocean floor. arrowright

Why does the input force have to be greater than the force needed to lift the bale?

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.
