Each cart below is pushed across a room with the same amount of force. Which cart will result in the greatest change in speed?

F.A 75 kg cart being pushed with a 200 N force
G.A 125 kg box being pushed with a 200 N force
H.A 350 kg box being pushed with a 200 N force
J.A 450 kg cart being pushed with a 200 N force

Answers

Answer 1

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)

a = F / m

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

For cart of mass 75 kgMass (m) = 75 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 75

a = 2.67 m/s²

For cart of mass 125 kgMass (m) = 125 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 125

a = 1.6 m/s²

For cart of mass 350 kgMass (m) = 350 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 350

a = 0.57 m/s²

For cart of mass 450 kgMass (m) = 450 KgForce (F) = 200 NAcceleration (a) =?

a = F / m

a = 200 / 450

a = 0.44 m/s²

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)

Answer 2

Answer:

D

Explanation:

F. 200-75=125

G. 20-125=75

H. 350-200=150

J. 450-200=250

250 is the biggest number so it has the biggest change

If 48.3g of iron is completely rusted in oxygen to produce 62.5g of iron (III) oxide, how many grams of oxygen are involved in the reaction?

Answers

The amount of oxygen involved in the reaction would be 20.7 g

The equation of rusting of iron is as follows:

[tex]4Fe + 3O_2 ---> 2Fe_2O_3[/tex]

The mole ratio of Fe to O2 is 4:3.

Mole of 48.3 g Fe = mass/molar mass

                               = 48.3/56

                                = 0.8625 moles

Equivalent mole of O2 = 0.8625 x 3/4

                                       = 0.6469 moles

Mass of 0.6469 moles O2 = mole x molar mass

                                             = 0.6469 x 32

                                              = 20.7 g

Why does a solid fill only part of a closed jar while the same mass of a gas fills the whole jar?

Answers

Answer:

because of atom don't put that as an answer

Explanation:

i need point to do finals

The different behavior of particles in solids and gases, including the intermolecular forces and kinetic energy, leads to solids filling only part of a closed jar while the same mass of a gas fills the whole jar. A solid fills only part of a closed jar, while the same mass of a gas fills the whole jar due to the differences in the behavior of particles in each state of matter.

1. Solid: In a solid, the particles are tightly packed and held in a fixed position. They have a definite shape and volume. The intermolecular forces between the particles are strong, preventing them from moving freely. As a result, solids occupy a specific amount of space within a container.

2. Gas: In a gas, the particles are spread out and move freely. They have no definite shape or volume. The intermolecular forces between the particles are weak, allowing them to move and fill the available space. As a result, gases can expand to fill the entire volume of a container.

When the same mass of a gas and a solid are placed in a closed jar, the gas particles have higher kinetic energy and are more mobile. They collide with each other and the walls of the container, exerting pressure and spreading out to occupy the entire space. Since the intermolecular forces are weak, the gas particles are not constrained by a fixed arrangement.
