Atiny object contains 5.54 x 10^12 protons and 4.71 x 10^12 electrons. what is the net charge on the object?

The net charge on the object is 0.1328 μC.

Explanation:

Given that,

Proton

Electron

We need to calculate the net charge on the object

Using formula of net charge

Where, Q = net charge

p = protons

e = electron

Put the value into the formula

Hence, The net charge on the object is 0.1328 μC.

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.)
