Now Safiya and Amy try a homework problem. Consider an electron moving with a speed of 8.70 106 m/s at right angles to a constant magnetic field, with B = 1.7 T. What is the radius of the circular path of the electron? r = m

Radius of circular path will be

Explanation:

Mass of electron

Charge on electron

Speed of electron is given

Magnetic field is given B = 1.7 T

We have to find the radius of the circular path

Radius of circular path is equal to , here m is mass v is velocity q is charge and B is magnetic field

So

So radius of circular path will be

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
