A wave travelling through a material has a frequency of 50 Hz and a wavelength of 0.40 m. How long does it take the wave to travel 100 m through this material?

velocity = frequency x wavelengthvelocity = 50 * 0.40velocity = 20 m/svelocity = distance / timetime = distance / velocitytime = 100 / 20time = 5sAnswer is 5s.

What is the general equation for the alpha-decay of a nucleus X, with nucleon number A and proton number Z, into nucleon Y??

A Z X --> A - 4 z - 2 Y + 4 2 α During alpha-decay, the nuclus emits an alpha particle which consists of two protons and two neutrons (a totoal of 4 nucleons). Therefore the new nuclide formed will have a...

Find the value of 'x' and state which angle on triangle ABC is smallest. A = right angle, B = 2x + 30, C = 2x

Where the angles of a triangle A+B+C = 180 degrees, then if follows that (where A = 90, B = 2x + 30, C = 2x):180 = 90 + 2x + 30 + 2x180 = 120 + 4x60 = 4x15 = xTherefore, it follows that A = 90, B = 60, C = 1...
