1a. The theoretical yield of Fe₂O₃ obtained is 17.14 g

1b. The percentage yield of Fe₂O₃ obtained is 82.9%

2. The molarity of the KCl solution is 0.04 M

Balanced equation

4Fe + 3O₂ —> 2Fe₂O₃

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 4 × 56 = 224 g

Molar mass of Fe₂O₃ = (56×2) + (16×3) = 160 g/mol

Mass of Fe₂O₃ from the balanced equation = 2 × 160 = 320 g

SUMMARY

From the balanced equation above,

224 g of Fe reacted to produce 320 g of Fe₂O₃

Therefore,

12 g of Fe will react to produce = (12 × 320) / 224 = 17.14 g of Fe₂O₃

Thus, the theoretical yield of Fe₂O₃ is 17.14 g

Percentage yield = (Actual / Theoretical) × 100

Percentage yield of Fe₂O₃ = (14.21 / 17.14) ×100

Percentage yield of Fe₂O₃ = 82.9%

Molarity = mole / volume

Molarity of KCl = 5.1 / 126.81

Molarity of KCl = 0.04 M

Newton's First Law

Newton's first law states that an object thats moving wants to stay moving and an object that's not moving doesn't want to move. An example of Newton's First Law in football is throwing the ball. When the QB puts forward force on the ball and then lets go, the ball wants to keep moving forward. The more force he puts on the ball the more inertia it will have. And the more mass the football has the more force has to be put on it.

Newton's Second Law

Newton's Second Law states that objects with more mass require more force to move. An example of Newton's Second Law in football is tackling. Bigger players require more force to move. And smaller players require less force to move. The more inertia and mass the object has that is moving the other object, and the less friction the object that is being moved has on the ground will make it easier to move.

A big football player has more mass than a smaller football player so he will require more force to be moved.

He needs to put more force on the other player than a chair to move him because the player has more mass.

Newton's Third Law

Newton' Third Law states that if there is an action there will be equal and opposite reactions. An example of Newton's Third Law in football is stiff arming. when you push another player away from you while running. It will push them away while also pushing you away from them. The force of the other player moving at him force is put on the player too. Also how much inertia the other player has increases the amount of force put on the player stiff arming.

when he stiff arms he pushes the other player away from him and him away from the other player.

When he puts force on the ball then releases it, it continues to fly forwards.

When he pushes the ball forward and releases it will continue to move.

because he pushes the other player away the other player moving at him also puts force on him.

Answer:A force can be described as a push or a pull. Pushes and pulls can be seen to act on objects when they begin to move, speed up, slow down or change direction.

The image gallery on this page shows children at play using push and pull actions to move objects. Children use push and pull all the time while at play. While playing, students learn to manipulate objects and materials and make observations about their actions.

Teachers may use this teaching resource over a number of lessons to explore and develop their students' understanding that a push or a pull affects how an object moves or changes shape.

Explanation:

Answer:

The coil keeps spinning because of the interaction between the magnetic field generated by the flow of electricity in the coil and the magnetic field of the permanent magnet surrounding it. This interaction creates a force that causes the coil to rotate continuously.

As for the direction of the electricity flow, it depends on the design of the coil and the direction of the magnetic field. If the coil is connected to a direct current (DC) source, the electricity will flow in a single direction. If the coil is connected to an alternating current (AC) source, the direction of the electricity flow will change periodically, typically many times per second.

In general, the direction of the electricity flow can be determined using Faraday's law of electromagnetic induction, which states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which will cause electricity to flow in the conductor. The direction of the induced EMF and the resulting electricity flow will depend on the direction of the changing magnetic field and the direction of the coil.

Explanation:

Answer:

The inertia of the rotating coil carries it through half of a turn, past the insulating paint. When the electric current starts to flow again, the twisting force is in the same direction as it was before. The coil continues to rotate in the same direction.

The permanent magnets exert forces on the electrical currents flowing through the loop of wire.

Answer:

The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.

Explanation:

To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:

Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)

Since vi = 0 and vf = 0, the equation simplifies to:

0 = 0 + 2 * a * d

Solving for acceleration (a), we have:

2 * a * d = 0

a = 0

Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.

The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.

The following steps will guide you on how to calculate the braking force:

Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.

Step 2: Determine the distance travelled by the lorry, which is 60 m.

Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.

However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.

This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t

Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.

Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at

Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.

Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

Newton's first law states that unless acted with by an external force, the dinnerware will remain immobile. The horizontal force acting on the objects on the table in this example is the frictional force between them and the table cloth, which sets them in motion.

According to Newton's second law, the force required to accelerate the tableware is proportional to the rate of acceleration. When the tablecloth is slowly pushed, the dinnerware adjusts to fit the modest rate of acceleration and moves with it. When the tableware is pulled swiftly, it needs to accelerate at a faster pace to keep up; but, the effort required to do so is larger than the frictional force available, thus it lags behind. The tableware 'stays put' when the cloth is tugged quickly.''

This question covers one of the most enigmatic aspects of our universe! Inertia is the easy answer to your question. In other words, because of inertia, when you remove the table linen off a table full of dishes, the dishes stay put. Matter's inertia is a property that characterizes its resistance to change in motion. When you're jogging and try to turn, you'll find that the faster you go or the bigger you are, the more difficult it is to shift direction.

Other examples of inertia include the following. Another example of inertia is when you are riding in a car and the driver rounds a corner and you feel pushed toward the door or over to the driver.

The dishes' inertia comes into play when the magician removes the cloth from underneath them.

The propensity of objects to resist changes in their state of motion is known as inertia. The dishes seek to preserve their original condition of rest when the fabric is quickly pulled because of inertia.

The dishes' and the cloth's friction is insufficient to rapidly overcome this inertia. As a result, the dishes initially hold in place before friction gradually takes over and causes them to slide.

Thus, the careful balance between inertia and friction results in this seemingly supernatural effect, producing a visually stunning illusion.
