<span>The volcanoes of USA are located along the west coast, at the subduction of the Pacific and North American tectonic plates. During the 20th century there were only two eruptions in continental USA; Lassen in 1915, and Mt St Helens in 1980. Alaska and Hawaii contain currently active volcanoes. hope this helps:)</span>
The frequency of the wave is the frequency of that sine function ... 2,000π ... but that's the <u>angular </u>frequency, in radians per second.
To convert angular frequency to Hz, we have to divide by 2π.
So the frequency of this wave is <em>1,000 Hz. </em>
You can't.
Work = (force) x (distance) .
You can squeeze distance out of the speed, but there's no way to determine the FORCE being used.
If there's no friction and the car is traveling in a straight line, then NO force is needed to keep it going. It just keeps going. (Newton's 1st law of motion.)
