The answer is A. Opposites attract, hence the attraction during friction. Balloons and hair would be a great example.

Carlos is struggling with math. It is his most challenging subject and he is worried about a big test tomorrow. He has time to study, but isn't sure it is worth it.
Volume % = mole %
Molar mass of oxygen = 32kg/kmol
Molar mass of nitrogen = 28 kg/kmol
Density of nitrogen = Density of
oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen
Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20
kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3
Answer:
The intensity of the light that passes through a polarizer is 0.55I₀.
Explanation:
The intensity of the light that passes through a polarizer can be found using Malus's law:
<u>Where</u>:
I: is the intensity of the light that passes through a polarizer
I₀: is the initial intensity
θ: is the angle between the light's initial polarization direction and the axis of the polarizer = 42°
Therefore, the intensity of the light that passes through a polarizer is 0.55I₀.
I hope it helps you!
In-situ leaching or solution mining offers the least ground disruptive type of mining and waste. This type of mining only dissolves the uranium where it is under the ground then pump up to the ground and further processed through milling.
