The rest energy of the proton will be 938 MeV. The rest energy is related to the rest mass of the proton.
What is rest energy?The rest energy is the rest mass times the square of the speed of light of a particle at rest in an inertial frame of reference.
The rest energy is found as;
[tex]\rm E_R= mC^2\\\\ E_R=(1.67 \times 10^{-27})\times 3 \times 10^8)^2\\\\ E_R= 9.375 \times 10^8 / eV[/tex]
Convert into the mega electron volt;
[tex]\rm E_R= 938 \ MeV[/tex]
Hence, the rest energy of the proton will be 938 MeV

Explain how to get a positive electric charge
Answer:
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged
A 30 ohm resistor and a 20 ohm resistor are
connected in series with a 100 volt battery. What is
the electrical current that would pass through the
30 ohm resistor?
The current that would pass through the 30 ohms resistor is 2 A.
What is electric current?Electric current is the rate of flow of electric charge round a conductor.
To calculate the electric current that would pass through the 30 ohms resistor, we use the formula below
Formula:
I = V/Rt........... Equation 1Where:
I = Electric current passing through the 30 ohms resistorV = VoltageRt = Total or effective resistance of the resistors.From the question,
Given:
V = 100 voltsRt = (30+20) ohms (since both resistors are connected in series)Rt = 50 ohmsSubstitute these values into equation 1
I = 100/50I = 2 AHence, The current that would pass through the 30 ohms resistor is 2 A.

Answer:
The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.
The Law of conservation of mass governs the balancing of a chemical equation.
According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the produc

A 4.4 nC charge exerts a repulsive force of 36 mN on a second charge which is located
a distance of 0.70 m away from it. What is the charge (magnitude and sign) of the
second charge?
The magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C. The principal of the Columb's law is used in the given problem.
What is Columb's law?The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.
They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are the same.
The given data in the problem is;
q₁ is the charge 1 = 4.4 nC = 4.4 ×10⁻⁹ C
F is the repulsive force = 36 mN =36 ×10⁶ N
d is the distance = 0.70 m
The Coulomb force is found as;
[tex]\rm F = \frac{Kq_1q_2}{r^2}\\\\\ \rm 36\times 10^6 = \frac{9 \times 10^9 }{(0.7)^2} \times 4.4 \times 10^{-9} \times q_2\\\\\ q_2 = 8.6241 \times 10^{-19 } \ C[/tex]
