Because oil is a lubricant which reduces friction between our hands and glass. Less friction and it tends to slip so yes , it is related to friction
The strength of the fireman in vertical direction will be given by F = m * g. Then, the work done will be given by definition by W = F * d. Substituting the expression of the Force in that of the work, we have that the work will be W = m * g * d. Substituting the given values and assuming that g = 10m / s ^ 2, we have a total work of W = (73) * (10) * (9) = 6570 J
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.

Answer:We have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The Earth's axis is tilted at an angle of 23.5 degrees. This means that the Earth is always "pointing" to one side as it goes around the Sun.

Answer:
a.) F = 3515 N
b.) F = 140600 N
Explanation: given that the
Mass M = 74kg
Initial velocity U = 7.6 m/s
Time t = 0.16 s
Force F = change in momentum ÷ time
F = (74×7.6)/0.16
F = 3515 N
b.) If Logan had hit the concrete wall moving at the same speed, his momentum would have been reduced to zero in 0.0080 seconds
Change in momentum = 74×7.6 + 74×7.6
Change in momentum = 562.4 + 562.4 = 1124.8 kgm/s
F = 1124.8/0.0080 = 140600 N
