Answer:

Quarks are usually defined as sub-atomic particles that are combined with one another and results in the formation of hadrons, of which the protons and the neutrons. They are a little heavier than the electrons and have a size of about 10^-18 m.

There are a total of 6 types of quarks, and they are as follows-

Top quark

Bottom quark

Up quark

Down quark

Strange quark

Charm quark

The up-quark is commonly represented as u-quark, and it forms the lightest of all the quarks. It is one of the main constituents of matter. It occurs along with the down-quarks and forms the neutron.

The drag force pushes opposite your motion as you ride a bicycle. If you double your speed, what happens to the drag force?

timurjin [86]

Answer: The drag force goes up by a factor of 4

Explanation:

The Drag Force equation is:

$F_{D}=\frac{1}{2}C_{D}\rho A_{D}V^{2}$ (1)

Where:

$F_{D}$ is the Drag Force

$C_{D}$ is the Drag coefficient, which depends on the material

$\rho$ is the density of the fluid where the bicycle is moving (air in this case)

$A_{D}$ is the transversal area of the body or object

$V$ the bicycle's velocity

Now, if we assume $C_{D}$ , $\rho$ and $A_{D}$ do not change, we can rewrite (1) as:

$F_{D}=C.V^{2}$ (2)

Where $C$ groups all these coefficients.

So, if we have a new velocity $V_{n}$ , which is the double of the former velocity:

$V_{n}=2V$ (3)

Equation (2) is written as:

$F_{D}=C.V_{n}^{2}=C.(2V)^{2}$

$F_{D}=4CV^{2}$ (4)

Comparing (2) and (4) we can conclude the Drag force is four times greater when the speed is doubled.

Identify where the solid would be found after distillation is complete.

dimaraw [331]

Bottom of the distillation flask

Explanation:

The solid in the mixture to be separate would be found at the bottom of the distillation flask.

Distillation is a separation technique for differentiating the components of mixtures based on the differences in their boiling points.

Distillation is used to recover solvents from solution.
The solutes are then left behind in the flask as the solvent boils out as vapor.
The solution is boiled in a distillation flask to vaporize the solvent.
The vapor is made to condense back into liquid by means of a condenser.
The pure liquid called distillate is collected in the receiver.
The solute which is the solid remains in the distillation flask
