The magnitude of the force acting on the body is 4000 Newtons.

To find the magnitude of the force, we can use Newton's second law of motion, which states that the force applied to an object is equal to the product of its mass and acceleration.

The given information includes the mass of the body (80 kg) and the resulting velocity (10 m/s). However, since the time duration (0.2 seconds) is also provided, we can use it to calculate the acceleration of the body.

The formula to calculate acceleration is:

Acceleration = Change in Velocity / Time

The change in velocity can be calculated by subtracting the initial velocity (which is 0 m/s as the body is at rest) from the final velocity:

Change in Velocity = Final Velocity - Initial Velocity

Change in Velocity = 10 m/s - 0 m/s

Change in Velocity = 10 m/s

Now, we can calculate the acceleration:

Acceleration = Change in Velocity / Time

Acceleration = 10 m/s / 0.2 s

Acceleration = 50 m/s²

Finally, we can calculate the magnitude of the force using Newton's second law:

Force = Mass x Acceleration

Force = 80 kg x 50 m/s²

Force = 4000 N

Therefore, the magnitude of the force acting on the body is 4000 Newtons.

The question in english language is as follows:

What is the formula of 4-ethyl-5-propyl-3,4,7-trimethyldecane?

Answer:

About $5.65x10^15 or $5,650,000,000,000,000

Explanation:

Given:

Volume of seawater: 2.3 mL

Grams of gold: 4.0 x 10^-10

Total volume of the ocean: 1.5 x 10^21

Price of gold: $21.66/g

Need:

1000 mL = 1 L

Find:

Dollar worth of all the gold in the world's oceans

Steps:

1. We know that there is 4.0 x 10^10 g of gold in 2.3 mL of seawater, therefore we can write it like this:

2. In order to find the amount of gold in the entire ocean we need to cancel out the 2.3 mL of seawater on the bottom. To do this we will use the volume of the entire ocean (1.5 x 10^21 L). Before we plug it into the equation, we have to match the units of the mL and the L. We will use the 1000mL = 1 L to accomplish this. The formula should now look like this:

\(\frac{4.0*10^{-10}g }{2.3mL} \frac{1000mL}{1L} \frac{1.5*10^{21}L}{1}\)

3. Solve the equation to find the amount of gold in all the oceans:

\(\frac{4.0*10^{-10}g }{2.3mL} \frac{1000mL}{1L} \frac{1.5*10^{21}L}{1} = 2.61 x 10^{14} g\)

4. Now since we found the amount of gold in all the oceans we can use this to find the total worth of all of it. We can do this by multiplying all the grams of the gold by the price of gold per gram. It can be represented like this:

\(\frac{21.66 dollars}{1 gram} \frac{2.61*10^{14}g }{1}\)

5. Get the answer:

\(\frac{21.66 dollars}{1 gram} \frac{2.61*10^{14}g }{1} = 5.65 x 10 ^ {15}dollars\)

Answer:

Here is a bunch of info from my lesson to help you out...

Explanation:

All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample). Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property).

Physical properties can be extensive or intensive. Extensive properties vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature. For example, elemental sulfur is a yellow crystalline solid that does not conduct electricity and has a melting point of 115.2 °C, no matter what amount is examined (Figure 1.3.1

1.3.

). Scientists commonly measure intensive properties to determine a substance’s identity, whereas extensive properties convey information about the amount of the substance in a sample.

Answer:

Number of Significant Figures: 7

Explanation:

The Significant Figures are 9 7 4 9 0 0 0. Remember: the first zeros don't count!

Answer:

Either B or C (read the explanation)

Explanation:

B is the largest atom of carbon.

First, B is an atom and not an ion because the negative electron charges balance out with the positive proton charges to create a balanced net charge. Additionally, we only change the number of neutrons, which are neutral.

We know B is the largest because neutrons are much larger than electrons.  Therefore, an atom with the larger number of neutrons will be largest.

HOWEVER, if you're asking which atom has the larger electron cloud, C is your answer.

If there are more electrons, the pull on each electron from the protons will be less, and you can think of it as dispersing the same force across more variables. C will therefore have the largest electron cloud while D has the smallest.

Chemically active fluids primarily aid in the mobility of dissolved silicate components and facilitate the development of the mineral grains during metamorphism.

During metamorphism, chemically active fluids that are present between the mineral grains help to promote ion movement and the re-crystallization of both old and new minerals.

Rocks that have undergone metamorphism include igneous, sedimentary, and other types of metamorphic rocks. The variations include the creation of new minerals, an increase in grain size, and adjustments to the structure or texture of the rock, depending on the chemical composition of the original rock and the degree of metamorphism.

Explanation:

The balanced symbol equation for the Haber process, which is the industrial method for producing ammonia, is N2 + 3H2 → 2NH3

A. The Haber process is the industrial method for producing ammonia, and the balanced equation for the reaction is:

N2 + 3H2 → 2NH3

The atom economy for a product is the percentage of the total mass of reactants that becomes the desired product. For ammonia, the atom economy can be calculated as follows:

Molar mass of NH3 = 14.01 + 3(1.01) = 17.04 g/mol

Atom economy of NH3 = (2 mol NH3 x 17.04 g/mol) / [(1 mol N2 x 28.02 g/mol) + (3 mol H2 x 2.02 g/mol)] x 100% = 34.0%

B. To calculate the theoretical yield of ammonia, we need to use the given mass of nitrogen and the stoichiometry of the balanced equation. The molar mass of nitrogen is 28.02 g/mol, so 27.3 g of nitrogen is equal to:

27.3 g / 28.02 g/mol = 0.974 mol N2

According to the balanced equation, 1 mole of N2 reacts with 3 moles of H2 to produce 2 moles of NH3. Therefore, the theoretical yield of ammonia is:

Theoretical yield of NH3 = (0.974 mol N2) x (2 mol NH3 / 1 mol N2) x (17.04 g/mol NH3) = 33.1 g NH3

C. The percentage yield of the reaction can be calculated by dividing the actual yield of ammonia by the theoretical yield, and then multiplying by 100%. The actual yield of ammonia is given as 29.9 g:

Percentage yield of NH3 = (29.9 g NH3 / 33.1 g NH3) x 100% = 90.4%

D. The percentage conversion of hydrogen can be calculated by dividing the mass of hydrogen used in the reaction by the mass of hydrogen that would have been used if all of it had been consumed in the reaction. The mass of hydrogen used is 10.4 g, and the mass of hydrogen that would have been used if all of it had been consumed in the reaction is:

1( mol H2 x 2.02 g/mol) x (0.974 mol N2 / 1 mol N2) = 1.98 g H2

Therefore, the percentage conversion of hydrogen is:

Percentage conversion of H2 = (10.4 g H2 / 1.98 g H2) x 100% = 525% (This result is not possible, as the percentage conversion cannot be greater than 100%. It is likely that there was an error in the calculation or in the data provided.)

The original culture density (OCD) of a sample density would be 1,720,000 colony-forming units per unit volume.

The dilution factor is the ratio of the volume of the original sample to the volume of the final diluted sample. In this case, the final dilution factor is 10^-4, which means that the original sample was diluted by a factor of 10,000.

To calculate the OCD, we use the formula: OCD = CFU / Dilution Factor. In this case, the CFU count is given as 172 and the dilution factor is 10^-4.

Using the formula, OCD = 172 / 10^-4, we can simplify the calculation by converting the dilution factor to a whole number. 10^-4 is equivalent to 1 / 10,000.

Substituting the values, OCD = 172 / (1 / 10,000). Dividing by a fraction is equivalent to multiplying by its reciprocal, so OCD = 172 * 10,000.

Calculating the product, OCD = 1,720,000. Therefore, the original culture density of the sample would be 1,720,000 colony-forming units per unit volume.
