Answer 1

To determine the number of excess protons in a positively charged object, divide the object's charge by the charge of a single proton. The charge of 1 proton is +1.6 x 10^-19 C.

Step-by-step explanation:

To determine the number of excess protons in a positively charged object, we need to calculate the charge in charges of a single proton and then divide the object's total charge by the charge of a single proton. The charge of 1 proton is +1.6 x 10-19 C. Given that the object has a charge of +382 mC (millicoulombs), we can convert it to coulombs by multiplying by 10-3.

Now we can calculate the number of excess protons by dividing the object's charge by the charge of a single proton.

Number of excess protons = Object's charge / Charge of a single proton.
