Determine the debroglie wavelength for an electron moving at 7.3 x 107 m/sec.

a. 1.0 x 10-11 m

b. 5.1 x 104 m

c. 5.9 x 10-23 m

d. 2.9 x 10-7 m

A.

Explanation:

As we know that de Broglie wavelength is given by the formula

here we know that

mass of electron is given as

so here we have

answer: a ball

explanation: because it will bounce

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
