Answer:

I believe that the answer is that in physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.

The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.

The potential energy stored in a spring is known as elastic potential energy. The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.

For example, when a spring is compressed it acquires potential energy which will be converted to kinetic energy of the object impacted by the spring.

The elastic potential energy of spring is given as;

\(U_x = \frac{1}{2}kx^2\)

where;

Thus, we can conclude that, the elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.

5)Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. The moon's gravitation force is determined by the mass and the size of the moon. ... This means that if you went to the moon you would weigh less, even though your mass stays the same

6)Physical changes are changes that do not alter the identity of a substance. Chemical changes are changes that occur when one substance is turned into another substance. Chemical changes are frequently harder to reverse than physical changes.

7)Try to be as accurate as possible with your measurements, and then subtract the former from the latter to find the mass of the object. This process is commonly referred to as "taring."

8) i think ductility but im not sure

9)If only the form of a substance changes, you have observed a physical change. A common physical change occurs when matter changes from one phase to another. When an ice cube melts for example, it becomes liquid water.

10)Oil floats on the surface because water is heavier than oil. Scientists say that water is more dense than oil. This is why the oil always stays in the top container.

By using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.

The process of Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the producers whereas oxygen is a by-product that is used in the process of respiration and the extra will diffuse in the atmosphere. In the cellular respiration process,  oxygen and glucose are converted into water and carbon dioxide. Water and carbon dioxide are the waste material and ATP is the energy that is used in the process. In the photosynthesis process, carbon dioxide gas combines with water molecules forming glucose and oxygen gas while on the other hand, in the process of respiration, glucose combines with oxygen gas forming carbon dioxide gas, water, and energy in the form of ATP. This ATP is used for performing different activities by the cell.

So we can conclude that using one animal and one plant or tree in an experiment to show that cellular respiration and photosynthesis depend on each other.

Explanation:

Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.

Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:

Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.

Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.

Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.

Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.

Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.

Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.

The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.

1. Solid: A brick is a solid object that maintains a fixed shape and volume.

2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.

3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.

The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.

In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.

Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,

Using Formula:

K.E=\(1/2mv^{2}\)

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.125)(4)^{2}\)

K.E=\(1/2(0.125)(16)\)

K.E=1/2(2)

K.E=1

When the mass of the bottle is 0.250 kg, the Kinetic Energy  is

K.E=\(1/2(0.250)(4)^{2}\)

K.E=1/2(0.125)(16)

K.E=1/2(4)

K.E=2

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.375)(4)^{2}\)

K.E=1/2(0.375)(16)

K.E=1/2(6)

K.E=3

When the mass of the bottle is 0.500 kg, the Kinetic Energy  is

K.E=\(1/2(0.500)(4)^{2}\)

K.E=1/2(0.500)(16)

K.E=1/2(8)

K.E=4

Now we can calculate the change in kinetic energy (ΔKE):

ΔKE = KE(final) - KE(initial)

= 4 kg m*2/s*2 - 1 kg m*2/s*2

To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.

To find the volume of the block using the measurements provided.

1. Calculate the change in water volume:

The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.

2. Convert the change in water volume to cubic centimeters:

Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.

3. Determine the volume of the block:

When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.

By following these steps, we can find the volume of the block based on the provided measurements.

Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.

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

The gravitational potential energy of the ball can be modelled in

relation to the velocity attained by the ball rolling down the ramp.

A model of the GPE of the ball is as follows;

The gravitational potential energy, GPE, is given as follows;

GPE = m·g·Δh

Where;

m = The mass of the ball

g = The acceleration due to gravity

Δh = The change in elevation of the ball

The gravitational energy of the ball at the starting (lowest) part of the

ramp, where Δh = 0, is 0.

When a small amount of energy is applied to the ball by moving it with a

slow speed, the ball moves some distance up the ramp then stops.

When a higher amount of energy is applied to the ball, the ball moves to

a higher point on the ramp.

When energy is applied to the ball, the energy is converted into

gravitational potential energy such that the height the ball reaches,

indicates the amount of gravitational potential energy in the ball.

Based on the model, we have;

Kinetic energy K.E. applied = GPE gained

Which gives;

\(\dfrac{1}{2} \cdot m \cdot v^2 = \mathbf{m \cdot g \cdot h}\)

\(v^2 = 2 \cdot g \cdot h\)
