Good Question!!! No one has found the answer to that question.

Kruka [31]3 years ago

Answer:

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!

Gravitational force is the force that attracts to objects with mass. ... This forces tries to pull masses together, that is why attractive in nature. For example: When ball is thrown upwards it always come downwards after a certain height because the ball is pulled or attracted by the Earth's gravitation la force.

What is the molarity of 1.5 liters of an aqueous solution that contains 52 grams of lithium fluoride, LiF, (gram-formula mass =2
denis23 [38]
The answer is (1) 1.3 M. The first thing you need to do is to convert the unit of gram to mole. The mol number of LiF is 52/26=2 mol. Then using the volume to calculate the molarity: molarity=2/1.5=1.3 M.

Describe how the properties of the compound carbon monoxide (CO) differ from the properties of the
ElenaW [278]

Explanation:

There is a clear cut difference between a compound and an element:

  • A compound is made up of substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
  • An element is a distinct substance that cannot be split-up into simpler substances. These substances are only made up of one kind of atom.

Compounds are formed so that unstable elements can attain stability.

Carbon monoxide is made up two elements: Carbon and oxygen that have combined chemically together.

  • Carbon monoxide is a toxic gas and it is different from oxygen atom and carbon atom.
  • Carbon is a solid but carbon monoxide is a gas.
  • Oxygen atom does not exists on its own but it exists as Oxygen gas O₂
  • The properties of carbon monoxide clearly differ from that of oxygen and carbon.

A bug travels at the rate of 3.0 miles per hour. How fast is this in um/nsec? Hint: 2.54cm = 1 inch and 1 mile = 5,280 feet
kirza4 [7]
Note that
1 mi = 1609.34 m = 1609.34 x 10⁶ um
1 h = 3600 s = 3600 x 10⁹ ns

Therefore the speed of the bug is
 (3.0 mi/h)*(1609.34x10⁶ um/mi)*(1/3600x10⁹ h/ns)
(3.0 \,  \frac{mi}{h}) (1609.34\times10^{6}\, \frac{um}{mi} )( \frac{1}{3600\times 10^{9}}  \frac{h}{ns} ) =1.34\,\times 10^{-3} \,  \frac{um}{ns}

Answer: 1.34 \times 10^{-3} \,  \frac{\mu m}{ns}

When the temperature of the air is 50°C, the velocity of a sound wave traveling through the air is approximately
Rainbow [258]
In this item, we are to calculate for the speed or velocity of sound in air with a temperature of 50°C. The dependence of the velocity of sound in temperature is expressed in the following equation:
                        v = 331 m/s + (0.6 m/s°C)(T)
where v is the velocity and T is temperature. 

Substituting the known values from the given,
                        v = 331 + (0.6)(50) = 361 m/s

Thus, the velocity of sound in air at 50°C is approximately 361 m/s.
