When you jump on a trampoline, your body has kinetic energy that changes over time. As you jump up and down, your kinetic energy increases and decreases with your velocity. Your kinetic energy is greatest, just before you hit the trampoline on the way down and when you leave the trampoline surface on the way up.

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Kelli and Jarvis exert a force of 524 N on a 158- kg (m) piano.

The friction force, which opposes this force, is 418 N.

The net force (F) is the difference between both forces.

F = 524 N - 418 N = 106 N

We can calculate the acceleration (a) of the piano using Newton's second law of motion.

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object.

a = F/m = 106 N/158kg = 0.671 m/s²

The piano start from rest (u = 0 m/s) and moves with an acceleration of 0.671 m/s² for 1.44 s.

We can calculate its final velocity (v) using the following kinematic equation.

v = u + a × t

v = 0 m/s + 0.671 m/s² × 1.44 s = 0.966 m/s

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Answer

When a carbonated drink is at room temperature, it is less fizzy and taste flat. Cool it down and it will taste better because the drink is designed to be drank at a lower temperature for optimal fizz and taste.

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.

Explanation:

Taking into account the bond energy, the O=O bond is the strongest and the O–H bond is the weakest.

The bond energy is the average total energy that would be released by the formation of a mole of chemical bonds, from their constituent fragments (all in the gaseous state).

In other words, the normal or standard bond enthalpy is defined as the change in enthalpy or heat released, under standard conditions of 1 atmosphere and 25ºC, that accompanies the reaction of formation of one mole of bonds from the isolated atoms in gaseous state.

The higher the bond energy, the stronger and more stable the bond will be.

So, taking into account all the previous, the O=O bond is the strongest and the O–H bond is the weakest.

Taking into account the room temperature and pressure, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

RTP refers to Room Temperature and Pressure. Pressure is 1 atm and Temperature is 298K. In this case, one mole of any gas has a volume of 24 dm³ or 24,000 cm³. This volume is called the molar volume of a gas.

In other words, the molar volume (the amount of space occupied by one mole) of any gas is 24dm³ (1 mol of gas molecules occupies 24.0 dm³).

Therefore, the amount of volume occupied by any gas can be calculated by multiplying the number of moles of gas by 24dm³:

Volume = Moles of gas× 24 dm³

So, the number of moles can be calculated as:

Moles of gas= Volume÷ 24 dm³

In this case, you know that volume if sulfur dioxide gas is 10 dm³. So, replacing:

Moles of gas= 10 dm³ ÷ 24 dm³

Solving:

Moles of gas= 0.4167

Finally, there are 0.4167 moles in 10 dm³ of sulfur dioxide gas.

The cart with the greatest change in speed is the cart with a mass of 75 Kg

Acceleration is defined as the change in velocity of an object with time. Also, acceleration is related to the force and mass according to the following equation:

Acceleration (a) = Force (F) / mass (m)

To answer the question, we shall determine the acceleration of each cart.

a = F / m

a = 200 / 75

a = F / m

a = 200 / 125

a = F / m

a = 200 / 350

a = F / m

a = 200 / 450

From the above illustrations, we can see that the cart with a mass of 75 K has the greatest change in speed (i.e 2.67 m/s²)
