A skydiver fall at 10 m/s. If he falls for 15 seconds, how many meters did he fall?
To find out how many meters the skydiver fell, you can use the formula:
distance = speed x time
distance = 10 m/s x 15 seconds
distance = 150 meters
Therefore, the skydiver fell 150 meters during his 15-second fall.
What is speed?Speed is a scalar quantity that describes how fast an object is moving. It is typically measured in units of distance per time, such as meters per second (m/s) or kilometers per hour (km/h).
Speed is different from velocity, which is also a measure of an object's movement, but velocity is a vector quantity and it describes an object's speed in a certain direction. Speed is the magnitude of velocity and it's a scalar quantity which only describes how fast an object is moving without considering direction. The formula for speed is distance traveled divided by the time it takes to travel that distance.

The exact mass of the second isotope is 224.15 u
The following equation can be used to get the average atomic mass:
average atomic mass = (% of the first isotope/100) x mass of the first isotope+ (% of the second isotope/100) x mass of the second isotope)
Due to this:
Initially isotope:
% = 62.94 %
Mass = 224.75 u
The second isotope is:
Since there are only two isotopes of the element, the second percentage is equal to 100 minus the first percentage.
% = 100 % - 62.94 % = 37.06 %
Assume Mass = x u.
Average Mass = 223.13 u, as stated
Thus,
average atomic mass = (% of the first isotope/100) x mass of the first isotope+ (% of the second isotope/100) x mass of the second isotope)
223.13 = (62.94 % x 224.75) +( 37.06 % x 223.13 )

the specific heat capacity of the metal is 0.3427 J/g°C.
Water mass is 140.0 g.
Water started out at a temperature of 20.0 °C.
100 g is the mass of a specific metal.
Metal's initial temperature is 95.0°C.
Water and metal's combined final temperature is 24.6°C.
The water will gain heat because its initial temperature is lower than that of the metal, which will lose heat because it is at a greater initial temperature. Therefore, heat obtained by water equals heat lost by metal.
formula: (mass water)(finalT- initalT) = (mass metal)(initialT- finalT)(Cp metal) ( Cp water)
after entering the provided info we obtain,
(100g )(95°C -24.6°C)
(140.0g)(24.6°C–20.0°C) = (Cp metal) (4.184 J/g°C)
The formula is (100g)(70.4°C)(Cp metal)=(140.0g)(4.6°C)(4.184 J/g°C)
7863.7 g°C = 2694.5 J (Cp metal)

Hydrocarbon are defined as an organic compound consisting of hydrogen and carbon. These are the examples of group 14 hydrides. Hydrocarbons are colorless compounds and these are hydrophobic. The odors of hydrocarbons are weak.
Suppose we have 100 g of the given compound. if there are 82.76 g of carbon then it should have 17.24 g of hydrogen in it.
The molar mass of carbon is 12.01 g/mol.
The molar mass of hydrogen is 1.01 g/mol.
We have to calculate the number of moles.
Number of moles of carbon = 82.76 g / 12.01g/ mole
= 6.89 mole
Number of moles of Hydrogen = 17.24 g / 1.01g/ mole
= 17.07 mole
Now we have to divide the moles of carbon and hydrogen by the smallest value.
For carbon, 6.89 mole / 6.89 mole = 1
For Hydrogen, 17.07 mole / 6.89 mole = 2.5
Then the ratio becomes 2: 5. so the empirical formula is [tex]C_{2}H_{5}[/tex] having the weight of 29.07 g / mole.
n = molecular mass / weight of empirical
= 58.1 g/ mole / 29.07 g / mole

An organic substance made up of hydrogen and carbon is referred to as a hydrocarbon. These group 14 hydride examples are shown. Hydrocarbons are invisible molecules that repel water. Hydrocarbons have hardly detectable smells. Consider that we have 100 g of the specified chemical. 17.24 g of hydrogen should be present if there are 82.76 g of carbon.
Carbon has a molar mass of 12.01 g/mol.
Hydrogen has a molar mass of 1.01 g/mol.
We must determine the amount of moles.
Number of moles of carbon = 82.76 g / 12.01g/ mol = 6.89 mole
Number of moles of Hydrogen = 17.24 g / 1.01g/ mol = 17.07 mole
The next step is to divide the moles of hydrogen and carbon by the least number. 6.89 mole / 6.89 mole equals one for carbon.
17.07 moles / 6.89 moles of hydrogen equal 2.5
Then, the ratio changes to 2 to 5. Therefore, the empirical formula weighs 29.07 g per mole.

The volume of 6 M acetic acid required to fully react with 0.5 g of sodium bicarbonate is 0.099167 mL.
To determine the volume of 6 M acetic acid required to fully react with 0.5 g of sodium bicarbonate (NaHCO3), we need to use the balanced equation for the reaction between acetic acid and sodium bicarbonate.
The balanced equation is:
CH3COOH(aq) + NaHCO3(aq) → CH3COONa(aq) + H2O(l) + CO2(g)
From the balanced equation, we know that one mole of acetic acid reacts with one mole of sodium bicarbonate.
we know that the molarity is moles of solute per liters of solvent, so the number of moles in 0.5 g of sodium bicarbonate is 0.5/84 = 0.00595 mol
And since one mole of acetic acid reacts with one mole of sodium bicarbonate, we know that we need 0.00595 mole of acetic acid to fully react with 0.5 g of sodium bicarbonate.
If we know the molarity of acetic acid, we can calculate the volume of acetic acid required to react with 0.5 g of sodium bicarbonate. we have

Which two changes would decrease the gravitational force between two objects?
Decreasing mass and increasing distance between two objects decrease the gravitational force between two objects.
What is gravitational force?The concept of gravitational force is described by Newton's Law of Universal Gravitation. This gravitational force is indeed a form of non-contact force; it is a constant attracting and constrictive force in nature.
The attraction force felt by two or even more objects into contact is known as gravitational force. The Gravitational Force Formula, which was derived from Newton's Universal Law of Gravitation, is used to calculate the gravitational force.
F=GmM/r²
From formula we can see that decreasing mass and increasing distance between two objects decrease the gravitational force between two objects.
Therefore, decreasing mass and increasing distance between two objects decrease the gravitational force between two objects.
