Hi! :)
You find it hard to ride faster on your bike because a force is pushing back on you. What type of force is slowing you down?
C) Air resistance!
Have a BEAUTIFUL day~
Answer:
8
Explanation:
octet rule: Atoms lose, gain, or share electrons in order to have a full valence shell of eight electrons. Hydrogen is an exception because it can hold a maximum of two electrons in its valence level.
A heterogeneous mixture may be mistaken for a pure substance. It can be separated using distillation. Concrete is an example of this heterogeneous kind of mixture.
<h3>What is a solute?</h3>
A solute is a material dissolved in another substance known as a solvent in a homogeneous mixture made of two or more components.
A solute's concentration in a solution is a measure of how much of that solute is dissolved in the solvent in relation to the amount of solvent present, such as salt.
Solutes are the best cleaning agents and additives. Dissolved in many types of gasoline are cleaning agents and anti-knock additives.
A homogenous mixture consists of the same type of component. While the heterogeneous mixture consists of a different component.
It's possible to confuse a heterogeneous combination for a pure material. Distillation is a method that can separate it. An illustration of this heterogeneous type of combination is concrete.
Homogenous mixtures are visible.

0.6764*10^-10m
Explanation:
Using E= hc/wavelength
(4.14x10^-15)x(3.0x10^8)/(65x10^-12)=0.1911x10^5 eV=19.1 keV
So subtract the calculated energy from the given energy of scattered photons
9.11-0.75=18.36 keV
To find wavelength
Wavelength= hc/ E
[(4.14x 10^-15)x (3.0x10^8)]/(18.36*10^3) =0.6764^-10 m
C. 0.37V. A capacitor of 650x10⁻⁴F that stores 24x10⁻³C has a potential difference of 0.37V between its plates.
The key to solve this problem is using the capacitance equation C = Q/Vᵃᵇ, where C is the capacitance, Q the charge stored in the plates, and Vᵃᵇ the potential difference between the plates.
A 650x10⁻⁴F capacitor stores 24x10⁻³C, clear Vᵃᵇ for the equation:
C = Q/Vᵃᵇ -----------> Vᵃᵇ = Q/C
Solving
Vᵃᵇ = 24x10⁻³C/650x10⁻⁴F = 0.37V
