Electrons are accelerated in the picture tube of a television through potential difference of 8.00 * 10 ^ 3 V. (Use the values q e =1.60*10^ -19 kg and m e =9.109*10^ -31 kg.) Please please hel?

Explanation:

Give that,

The potential difference of the electrons,

We need to find the wavelength of the electrons.

Using the conservation of energy,

Put all the values,

So, the wavelength of the electrons is .

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

total distance/total time

(85 + 82)/(5+3)
