Wang co. Manufactures and sells a single product that sells for $450 per unit; variable costs are $270. Annual fixed costs are $800,000. Current sales volume is $4,200,000. Compute the break-even point in units

Answers

The break even point in units of the given financial ledger and values is gotten as; 44444 units

What is the break even point?

We are given;

Selling price = $450

Variable cost = $270

Fixed costs = $8000000

Sales volume = $4200000

Break even point is defined as the point at which the total costs and sales are equal or where revenue and expenses are equal. The formula to calculate the break-even point is;

Break even point = Fixed Costs/(selling price - variable costs)

Break even point = 800000/(450 - 270)

Break even point (in units) ≈ 44444 units

A body moving in the positive x direction passes the origin at time t = 0. between t = 0 and t = 1 second, the body has a constant speed of 24 meters per second. at t = 1 second, the body is given a constant acceleration of 6 meters per second squared in the negative x direction. the position x of the body at t = 11 seconds is

Answers

Integrate over [0, 1] to get the position of the body after 1 second. It starts at the origin, so we take x(0 s) = 0 m and using the fundamental theorem of calculus,

[tex]\displaystyle x(1\,\mathrm s) = x(0\,\mathrm s) + \int_{0\,\rm s}^{1\,\rm s} \left(24\frac{\rm m}{\rm s}\right) \, dt = 24 \, \mathrm m[/tex]

Then for time t ≥ 1 second, we integrate over [1, 11] to get the position after the next 10 seconds of motion. Since x(1 s) = 24 m, we have

[tex]\displaystyle x(11\,\mathrm s) = x(1\,\mathrm s) + \int_{1\,\rm s}^{11\,\rm s} \left(24\frac{\rm m}{\rm s} - \left(6\frac{\rm m}{\mathrm s^2}\right) t\right) \, dt = \boxed{-36\,\mathrm m}[/tex]

Without using calculus, in the 1st second of motion the body travels at constant speed, so it reaches a new position of

x = (24 m/s) (1 s) = 24 m

In the next 10 seconds, the body has constant acceleration and its velocity at time t is

v = 24 m/s - (6 m/s²) (t - 1 s)

so its "initial" velocity is 24 m/s, and after 10 seconds it attains a "final" velocity of

24 m/s - (6 m/s²) (11 s - 1 s) = -36 m/s

Then the body travels a distance x such that

(-36 m/s)² - (24 m/s)² = 2 (-6 m/s²) x   ⇒   x = - 60 m

and so the body's net change in position is 24 m - 60 m = -36 m.

Chase is trying to push a 210 kg boulder along the street. he applies a force of 180 newtons over a distance of 2.3 meters. how much work has chase done?

Answers

The work done by Chase in pushing the boulder over the given distance is 414J.

Work done

Work is simply the measure of energy transfer that takes place when an object is pulled or pushed by an external force over a given distance.

It is expressed as;

W = F × d

Where F is force applied d is the displacement.

Given the data in the question;

Mass of boulder m = 210kgForce applied F = 180N = 180kgm/s²Distance covered d = 2.3mWork done W = ?

To determine the work done by Chase, we substitute our given values into the expression above.

W = F × d

W = 180kgm/s² × 2.3m

W = 414kgm²/s²

W = 414J

Therefore, the work done by Chase in pushing the boulder over the given distance is 414J.

Use the ideal gas law equation to find the molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp.

Answers

The value of molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp is 80 g/mol.

What is ideal gas law?

The ideal gas law can be given as,

[tex]pV=nRT[/tex]

Here, (p) is pressure, (V) is volume, (n) amount of substance, (R) is ideal gas constant and (T) is the temperature.

For the given problem the modified ideal gas law, (written below) can be used.

[tex]PM=dRT[/tex]

Here, (M) is molar mass and (d) is density.

The molar mass of a 98.2 g sample of gas that fills a 50.0-liter container at stp. As the density is ratio of molar mass to volume. Thus,

[tex]d=\dfrac{40}{11.2}\\d=3.57\rm\; g/L[/tex]

The standard value of temperature and pressure is,

[tex]T=273\text{ K}\\p=1\rm\; bar[/tex]

The value of ideal gas constant (R) is 0.0821 atmL per mol K. Put these values in the above formula,

[tex]1\times M=3.57\times0.0821\times273\\M=80\rm\; g/mol[/tex]
