In normal Newtonian physics, it is usually considered that the Moon revolves around the Earth. With a lower mass, the Moon is affected by the Earth’s gravity more than the Earth is affected by the Moon. The two bodies orbit around the barycenter, a point of gravitational equilibrium approximately 3/4 of the Earth’s radius from the center of the planet.

The motions of these celestial bodies depend on your point of reference, and the mass of the bodies. The Earth, Moon, Sun, and the other planets are traveling in eccentric paths around the center of the Milky Way Galaxy, which is itself moving relative to the other galaxies in the vicinity.

How does distance affect work pls quick its 15 points pls keep it short pls help!!!!

ra1l [238]

The simple equation used to calculate work is force multiplied by distance, thus as this is the case increasing the distance by a certain amount, assuming the force applied to the object is constant, the amount of work you are doing on the box for instance pushing it, is going to be greater

Since you are pushing the box with the same force covering a greater distance with the force.

6.The original Listerine formula contains 26.9% alcohol (v/v). How many liters of Listerine can be prepared from 4.5 L of pure a

Burka [1]

Answer:

Amount of Listerine can be prepared = 16.73 (Approx)

Explanation:

Given:

Listerine formula contains = 26.9% alcohol

Amount of alcohol = 4.5 L

Find:

Amount of Listerine can be prepared

Computation:

Amount of Listerine can be prepared = (Amount of alcohol) / (Listerine formula contains)

Amount of Listerine can be prepared = 4.5 / 26.9%

Amount of Listerine can be prepared = 16.73 (Approx)

What volume of ethylene glycol (C2H6O2), a nonelectrolyte, must be added to 11.0 L of water to produce an antifreeze solution wi

shusha [124]

Answer:

The volume of ethylene glycol, we must add is 8.2 L

Explanation:

Let's apply the formula for the colligative property of Depression of freezing point, to solve this

ΔT = Kf . m . i

Where ΔT = Fussion T° in pure solvent - Fussion T° in solution

Kf = Cryoscopic constant (equal to 1.86 °C kg/mol for the freezing point of water)

m = molality (mol of solute in 1kg of solvent)

i = The number of ions dissolved in solution. As it is a non-electrolytic compound, the i values 1 (Van't Hoff factor)

0°C - (-25°C) = 1.86 kg°C/mol . m

25°C / 1.86 m/kg°C = m

13.4 = mol/kg

As water density is 1 g/ml, let's convert firstly 11L in mL

11L .1000 = 11000mL

In conclusion, we have 11000 g of water.

density = mass / volume

So, if we have 13.4 moles in 1 kg of water, how many moles of ethylene glycol do we have, in 11000 g of water.

11000 g = 11kg

1 kg _____ 13.4 moles of ethylene glycol

11 kg _____ (11 . 13.4)/1 = 147.4 moles

Molar mass of ethylene glycol = 62.07 g/m

Moles . molar mass = mass

147.4 m . 62.07g/m = 9149.1 g

Now we can apply density of ethylene glycol to find out the volume

Density ethylene glycol = ethylene glycol mass / ethylene glycol volume

1.11 g/ml = 9149.1 g / ethylene glycol volume

ethylene glycol volume = 9149.1 g/ 1.11 g/ml

ethylene glycol volume = 8242 mL

8242 mL = 8.2 L
