what is the soeed of a rock dropped off a cliff after 10 seconds of free fall?

Answers

Answer 1

The speed of the rock after 10 seconds of free fall would be approximately 122 meters per second (274 mph).

What is rock?

Rock is a solid material composed of a combination of minerals, such as quartz, feldspar, mica, and other minerals. Rocks are formed by the process of weathering, erosion, and deposition of material from the Earth's crust, which is composed of rock materials. Rocks are classified based on their composition and origin. The three main types of rocks are sedimentary, igneous, and metamorphic. Sedimentary rocks form from sediments that are transported and deposited by water, wind, or ice. Igneous rocks form when molten rock material cools and crystallizes. Metamorphic rocks form when existing rocks are changed by intense heat and pressure. Rocks are an important part of the Earth's surface and are used in many applications, such as construction, landscaping and the production of certain materials. Rocks can also provide information about the geologic history of an area.

Determine the molar mass of a 0.314-gram sample of gas having a volume of 1.6 l at 287 k and 0.92 atm. show your work.

Answers

As per Ideal gas equation, molar mass of the gas is 5.032 g/mo

We’ll begin by calculating the number of mole of the gas. This can be obtained as follow:

Volume (V) = 1.6 L

Temperature (T) = 287 K

Pressure (P) = 0.92 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) =?

According to Ideal gas equation , PV = nRT

0.92 × 1.6 = n × 0.0821 × 287

1.472 = n × 23.5627

Divide by 23.5627

n = 1.176 / 23.5627

n = 0.0624 mole

Finally, we shall determine the molar mass of the gas. This can be obtained as follow:

Mass of gas = 0.314 g

Number of mole = 0.0624 mole

Mole = [tex]\frac{mass}{molar mass}[/tex]

0.0624 = [tex]\frac{0.314}{molar mass}[/tex]

Cross multiply

0.0624 × molar mass of gas = 0.314

Divide by 0.0624

Molar mass of gas =  [tex]\frac{0.314}{0.0624}[/tex]

Molar mass of gas = 5.032 g/mo

Therefore the Molar mass of gas is 5.032 g/mo

A sample of air at room temperature in a 4.00 L container holds approximately 0.562 moles of O2and 2.11 moles of N2 along with other trace elements to total 2.67 moles. What is the mole fraction of N2 in the mixture

Answers

Taking into account the definition of mole or molar fraction, the mole fraction of N₂ in the mixture is 0.79.

Molar fraction

The molar fraction is used to express the concentration of a solute in a solution and expresses the proportion in which a substance is found with respect to the total moles of the solution, which are calculated by adding the moles of solute(s) and solvent.

The mole fraction "x" of the elements in a compound is defined as a ratio between the number of moles of each of the different elements present in the compound and the total number of moles of them:

x=number of moles of the solute÷ total number of moles

Mole fraction of N₂ in the mixture

In this case, you know that:

number of moles of N₂: 2.11 molestotal number of moles: 2.67 moles

Replacing in the definition of mole fraction:

x=2.11 moles÷ 2.67 moles

Solving:

x= 0.79

Finally, the mole fraction of N₂ in the mixture is 0.79.

A balloon contains a 10% glucose solution. The balloon is permeable to water but not to glucose. A beaker contains a 5% glucose solution. What will happen when the balloon is submerged in the beaker

Answers

The state of the balloon:

When the balloon is submerged in the beaker, the amount of water in the beaker will get reduced.  

What is Osmosis:    

Based on the concentration of solutes on both sides of the membrane, water will flow through a permeable membrane in a specific direction.

Hypertonic solution:

It means that there are more solutes present in the surrounding environment than in the cell itself.

Hypotonic solution:

In a hypotonic solution, the concentration of solutes inside the cell is higher than that outside the cell.

When comparing two solutions, the one with the larger solute concentration is hypertonic, and the one with the lower solute concentration is hypotonic. Isotonic solutions have an identical solute concentration.

While the solution in the beaker is hypertonic, Meaning that will draw water molecules out of the cell. As water molecules move from a location of high water potential (dilute solution) to a region of reduced water potential (10% glucose solution), the water from the 5% glucose solution will flow into the 10% one (concentrated solution)This is the reason why the amount of water decreases when the balloon is submerged in the beaker.

Both naturally occurring in the environment and used in manufactured goods are the metal lead. In the past, industrial sources and fuels used in on-road motor vehicles (such as cars and trucks) have been the main sources of lead emissions. Lead emissions from the transportation industry rapidly reduced by 95% between 1980 and 1999 thanks to regulatory measures in the U.S. to remove lead from gasoline for on-road motor vehicles, while lead levels in the air decreased by 94% over the same period.

They do not believe that Apollo is Phathons father or that Apollo makes the sun rise and set. In order to prove Phathon s friends wrong, Apollo hesitantly gives Phathon his chariot and horses. Apollo hurried to give directions. You have never driven my chariot before. You must make the horsesstay on the path. If you are too low, you will scorch the earth. I know, Father. Now watch me take off! shouted Phathon. Dawn stepped back and released her grip on the horses bridles. The horses pawed the ground and snorted with excitement. The sky begged for Dawns light, so she ran toward the horizon in her glowing gown to make the darkness fade. As Phathon was about to ascend, Apollo grabbed his arm and said, Please listen to me! If you go too high, you will warm the cold depths of the heavens, and the Bear or Snake or Scorpion will come alive! Phathon just laughed. My friends are waiting. Ive got to go! he shouted. With that, the chariot was off. It was a wild ride. Hour and Day were unruly and difficult to control. Phathon did not have his fathers strong arms or years of experience. The horses wove from side to side and bobbed up and down through the heavens, hitting everything in their way. The sun bounced along behind the chariot like a basketball. It grazed the stars and skidded along mountaintops, leaving charred remains behind. Phathons friends ran for cover as they watched the spectacle. Just as his father had warned him, the figures in the sky began to move. Suddenly the Scorpion lunged toward him, but Phathon ducked out of the way in time. The Snake lashed out and bit a wheel off the chariot. Apollo, witnessing the destruction, dashed up toward the heavens, but he was too late! The Bear had stirred from his icy hibernation and grabbed Phathon before his father could reach him. Apollo grabbed the reins and finally regained control of Hour and Day, but it was years before the earths mountaintops were white with snow again. The scorched areas became deserts where very little would grow. Phathon became a part of the constellations alongside the Bear, where his father could regretfully keep an eye on him.
