The lowest frequency standing wave pattern that can be made on a certain string on a cello is 220Hz (which is a musical "A" note). If the length of the string (called the "scale length" on a stringed instrument like a cello or guitar) is 695mm and if the mass of the string is 1.42g calculate:
a) the tension in the string.
b) the frequency of the 3rd overtone.
The solar wind is a thin, hot gas given off by the sun. Charged particles in this gas enter the magnetic field of the earth and can experience a magnetic force, calculate the radius of the circular path on which the particle would move if it were a..
