What determines the velocity of an object? Its acceleration at a given point in time Its weight in a given location Its displace

tensa zangetsu [6.8K]

We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

<h3>How do we know that displacement and time determine velocity?</h3>

We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is $\frac{d}{t}$ , meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.

Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.

What is the mole fraction of each component in a solution made by mixing 300 g of ethanol(C2H5OH) and 500 g of water?

Snowcat [4.5K]

Answer:

The mole fraction of ethanol and water in the solution are 0.19 and 0.81 respectively.

Explanation:

The Molar Fraction is a way of measuring the concentration that expresses the proportion in which a substance is found with respect to the total moles of the solution, which are calculated by adding the moles of solute (s) and solvent.

It is calculated by dividing the number of moles of one of the components by the total number of moles of the solution.

The sum of all the molar fractions of the substances present in a solution is equal to 1.

So, the expression to calculate the mole fraction is:

$Molar fraction (Xi)=\frac{moles of sudstance}{total moles of the solution}$

Being the molar mass of the compounds:

Ethanol 46 $\frac{g}{mol}$

Water 18 $\frac{g}{mol}$

the number of moles that represent the mass quantities is calculated as:

Moles of ethanol: 300 grams* $\frac{1 mol}{46 grams}$ = 6.52 moles
Moles of water: 500 grams* $\frac{1 mol}{18 grams}$ = 27.78 moles

So the total moles in solution are 6.52 moles + 27.78 moles = 34.3 moles

The mole fraction of ethanol in the solution is calculated as:

$mole fraction of ethanol=x_{ethanol} =\frac{6.52 moles}{34.3 moles}$

$x_{ethanol} =0.19$

The mole fraction of water in the solution is calculated as:

$mole fraction of water=x_{water} =\frac{27.78 moles}{34.3 moles}$

$x_{water} =0.81$

Then:

$x_{water} +x_{ethanol} = 0.81 + 0.19$

$x_{water} +x_{ethanol} =1$

<u><em>The mole fraction of ethanol and water in the solution are 0.19 and 0.81 respectively.</em></u>

How is pascals law used in the brakes of a car? <br><br> I’m giving 67 points!

bogdanovich [222]

Answer:

A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid. With that said; in a hydraulic brake system, if the piston in the master cylinder(the part your foot pushes on) is one inch square area and you push with 100 pounds, then 100 pounds per square inch is transmitted to all parts of the hydraulic system. Now if the brake caliper piston(the part that pushes against the brake pad) is 2 square inches then there will be a total of 200 lbs of force being applied by the wheel cylinder, because each square inch has 100 pounds pushing on it. This is basically how cars brake systems are designed in order to reduce the amount of force required by the driver.

Btw if u want to give 67 points u must multiply that by 2 since two people answer and they get half of 67. Im still happy with my 34 though!
