What is two masses exerting a force on each other an example of?

hoa [83]

Answer:

<em><u>universal law of </u></em><em><u>gravitation</u></em>

Explanation:

According to Newton's law of gravitation, every particle in universe attracts every other particles with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centres!

Consider two particles having masses m1 and m2 and are apart r units, then the gravitational force acting between them is given by

$F = G \cdot \frac{m1\cdot \: m2}{ {r}^{2} }$

Where G is universal gravitational constant or proportionality constant!!

PLEASE HELP DUE TONIGHT THANK YOU

Sav [38]

Answer:

check the attached image. hope it helps

Explanation:

a. What does mol/L mean? mol/L means Molar Concentration

b. Describe in your own words how mol/L compares to grams/liter. (similarities and differences)

<u>Similarities:</u><u> </u>mol/L and grams/liter both are units of concentration.

<u>Differences</u>:

mol/L concentration says how many moles of solute are present in 1L of solution.

grams/liter concentration says how many grams of solute are present in 1L of solution.

3. Describe at least 2 ways in the simulation to change each of the parameters:

a. Volume of solution= evaporating or adding more water

b. amount of solute=reducing the water or evaporating more water

c. Concentration of solute in solution = evaporating or adding more solute

What is the IUPAC name of the following compound?

inn [45]

Answer:

2,6–dimethylcyclohexanol

Explanation:

To name the compound given in the question above, we must first obtain the following:

1. Determine the functional group of the compound.

2. Locate the longest continuous carbon chain.

3. Identify the substituent group attached to the compound.

4. Locate the position of the substituent group.

5. Combine the above to obtain the name of the compound.

Now, we shall determine the name IUPAC name of the compound. This can be obtained as follow:

1. The compound contains the –OH group. Thus, the compound is an alcohol.

2. The compound is a cyclic compound with six carbon forming the ring. Thus, the parent name of the compound is cyclohexane. Thus, the presence of the –OH group changes the parent name of the compound to cyclohexanol.

3. The substituent group attached to the compound is methyl (–CH₃)

NOTE: There are two –CH₃ groups attached to the compound.

4. The position of the 1st –CH₃ group is at carbon 2, while the 2nd is at carbon 6.

NOTE: Counting is done from the carbon bearing the functional group.

5. Therefore, the name of the compound is:

2,6–dimethylcyclohexanol

60 kg of fuel was completely burnt for an experiment. The amount of heat energy was found to be 180000KJ. Calculate calorific va

FrozenT [24]

Answer:

3000 kJ/kg

Explanation:

The calorific value of a substance is the amount of heat produced per unit mass by the combustion of the substance.

It is given by:

$C=\frac{Q}{m}$

where

Q is the amount of heat released

m is the mass of the fuel

In this problem, we have:

m = 60 kg is the mass of fuel

$Q=180,000 kJ$ is the amount of heat released

Therefore, the calorific value of the fuel is:

$C=\frac{180,000}{60}=3000 kJ/kg$
