Mass and charge (A) determine the size of the electric potential and of electric potential energy.
Answer:
410.254 N
Explanation:
Force: This can be defined as the product of the mass of a body. The Unit of force is Newton (N)
Deduced from the question,
Force applied to the box to start it moving = Force of friction.
Fₐ = F
Where Fₐ = Force applied to the box to start it moving, F = Force of friction.
But,
F = μR.......................... Equation 1
Where R = normal reaction, μ = coefficient of static friction.
R = W = mg ( on a level surface)
Where m = mass of the box = 123 kg, g = acceleration due to gravity = 9.81 m/s²
R = 123×9.81
R = 1206.63 N.
Also, μ = 0.34
Substituting into equation 1
F = 1206.63×0.34
F = 410.254 N.
Thus the force applied to the box to start it moving = 410.254 N
Microorganisms can cause contagious diseases.
B.
The force of friction is given by:
f = μR, where μ is the friction coefficient and R is the reaction force, which will be equal to the weight.
100 = μ x 130
μ = 0.77
How a Inkjet printer uses electrical charges and tiny particles to print the image is discussed below.
We have a Inkjet printer which uses electrical charges and heat to fuse tiny plastic particles (called toner) to the paper.
<h3>What are Electrical Charges?</h3>
The sufficiency or deficiency of electrons in a body leads to the development of electric charge in a body. Its unit is Coulomb. It can be either Positive or Negative in nature.
According to the question -
The statement mentioned in the question is true. The inkjet printers use electrical charges and heat to fuse tiny plastic particles (called toner) to the paper. Printers attract toner particles (with the help of electric charge) to a transfer roller. Toner particles are pressed onto a piece of paper, while heat and pressure from the fuser unit permanently fix the image onto the page.
