There several physical quantities that can quantitatively describe the motion of objects. Some of them are distance and displacement.

Answer:

The best explanation is that the first person is grounded to the earth, and his/her body either draws up negative charges from the earth, or tend to conducts negative charges to the earth, depending on the charge on the balloon.

Explanation:

The earth is an infinite store for charges. In the first case where the second person brings a negatively charged balloon towards the first person, the negative charges on the balloon induces the first person's body to tend to attract the negative charges on the balloon through the first person's body to the positive charges within the earth. In the second case when again a positively charged balloon is brought near the first person's hair, the positive charges on the balloon induce the first person's body into drawing up negative charges from within the earth. This charges, and their opposite induced charges, create an attractive force between the hair strands and the balloons.

The acceleration of the object is 5 m/s². The result is obtained by using the Newton's second law.

The Newton's second law states that "The acceleration is directly proportional to the net force acting on an object and inversely proportional to the object's mass." It can be expressed as

a = ∑F/m

Where

An object with a mass of 12 kg is acted upon by a force of 60 N.

Find the acceleration of the object!

Using the Newton's second law formula, we get acceleration.

a = ∑F/m

a = 60/12

a = 5 m/s²

Hence, the acceleration of the object is 5 m/s².

The volume flux inside the rectangular duct is 0.028 m³/s.

Volume flux, also known as volumetric flow rate, is a measure of the volume of fluid passing through a given area per unit time. It is commonly expressed in cubic meters per second (m³/s). To calculate the volume flux in the given scenario, we can use the formula:

Volume Flux = (Air flow rate) / (Cross-sectional area)

First, we need to calculate the cross-sectional area of the rectangular duct. The area can be determined by multiplying the length and width of the duct:

Area = (138 mm) * (346 mm)

To maintain consistent units, we convert the dimensions to meters:

Area = (138 mm * 10⁻³ m/mm) * (346 mm * 10⁻³ m/mm)

Next, we can calculate the air flow rate using the given information. The air flow rate is given as 17 N/s, which represents the mass flow rate. We can convert the mass flow rate to volume flow rate using the ideal gas law:

Volume Flow Rate = (Mass Flow Rate) / (Density)

The density of air can be determined using the ideal gas law:

Density = (Pressure) / (Gas constant * Temperature)

where the gas constant (R) is given as 28.5 m/K, the pressure is 112 kPa, and the temperature is 20 degrees Celsius.

With the density calculated, we can now determine the volume flow rate. Finally, we can divide the volume flow rate by the cross-sectional area to obtain the volume flux.

After connecting the conducting wire, the spheres will redistribute charges until they both have a charge of -1C.

To determine the new charges on the spheres, we need to consider the principle of charge conservation, which states that the total charge before and after an interaction remains the same.

Let's assume that the spheres have charges Q1 and Q2 initially. In this case, Q1 = -3C and Q2 = +1C.

When a conducting wire is connected between the spheres, charge can redistribute until the system reaches equilibrium. Since the spheres are conducting, charges are free to move within them.

In the final state, the charges on the spheres will redistribute to reach a new equilibrium. Let's assume the new charges on the spheres are Q1' and Q2'.

According to the principle of charge conservation, the total charge before and after the connection remains the same:

Initial total charge = Q1 + Q2 = -3C + 1C = -2C

Final total charge = Q1' + Q2'

Since the total charge remains the same, we can write the equation:

Q1' + Q2' = -2C

Since the spheres are of equal size, we can assume that the charges redistribute equally:

Q1' = -1C

Q2' = -1C

To calculate the book value at year 3 (BV3), we need to determine the accumulated depreciation at year 3. The depreciation is calculated by subtracting the salvage value from the initial cost and dividing it by the number of years.

Initial cost: $20,000

Salvage value: $5,000

Number of years: 5

Depreciation per year = (Initial cost - Salvage value) / Number of years

Depreciation per year = ($20,000 - $5,000) / 5 = $3,000

Accumulated depreciation at year 3 = Depreciation per year * Number of years

Accumulated depreciation at year 3 = $3,000 * 3 = $9,000

Book value at year 3 = Initial cost - Accumulated depreciation at year 3

Book value at year 3 = $20,000 - $9,000 = $11,000

Therefore, the Book Value at year 3 (BV3) is $11,000 (option d).

To calculate the depreciation at year 3 (D3), we can simply use the depreciation per year, which is $3,000. Therefore, the Depreciation at year 3 (D3) is $3,000 (option b).

A liquids resistance to flow is called Viscosity

A phase change from the liquid phase to the vapour phase is called vaporisation (or vaporisation) of an element or molecule. Both evaporation and boiling result in vaporisation. Boiling is a bulk phenomenon, whereas evaporation is a surface phenomenon.

vaporisation is the process by which a material is transformed from its liquid or solid state into its gaseous (vapour) state. Boiling is the term for the vaporisation process when circumstances permit the creation of vapour bubbles within a liquid.

Evaporation is a typical process that takes place when a liquid transforms into a gas while raising the temperature or pressure. Boiling is an unnatural process in which the liquid is continuously heated to a point where it vaporises.

The transformation of a liquid into a gas is known as vaporisation.

The removal of anxiety-provoking ideas from awareness is called "c. repression".

It is a defense mechanism in which individuals unconsciously push unwanted thoughts or feelings out of their consciousness and into their subconscious mind.

This process is done to protect oneself from experiencing uncomfortable or painful emotions.

Repression is often used as a coping mechanism, especially in situations where individuals feel overwhelmed by emotions that they cannot handle.

It is important to note that repression is not a healthy long-term solution, as it can lead to psychological issues in the future.

Therapy can be beneficial in helping individuals confront and process their repressed emotions and ideas in a safe and healthy environment.

According to Newton's third law of motion, the reaction force exerted by the air on the balloon is equal in magnitude but opposite in direction to the action force exerted by the balloon on the air.

Given that the magnitude of the action force (F_balloon) is -3 N, the magnitude of the reaction force (F_air) will also be 3 N. The negative sign indicates that the forces are in opposite directions, but when considering magnitudes, we ignore the negative sign.

Therefore, the magnitude of the reaction force of the air pushing on the balloon is 3 N.

Explanation:

Answer:

Friction (traction) is the resistance between things. There's friction between your shoes and the ground. Without enough friction, you can slip and fall.

When you push a heavy box, it pushes back at you with an equal and opposite force (Third Law) so that the harder the force of your action, the greater the force of reaction until you apply a force great enough to cause the box to begin sliding.

When a person trips over a heavy box and falls to the floor, it's due to a combination of factors related to the laws of physics. Here's what happens:

1. Inertia: Every object tends to remain at rest or in uniform motion unless acted upon by an external force. This is Newton's first law of motion. When you're walking and suddenly trip over a heavy box, your body's forward motion is abruptly interrupted by the box. Your lower body and legs might still have forward momentum, causing you to stumble or fall.

2. Force of Gravity:The heavy box you trip over exerts a force of gravity on your body. When you collide with the box, this force pulls you downward, accelerating your fall towards the ground.

3. Friction and Contact Forces: When you trip over the box, there are contact forces and frictional forces involved. Your foot might get caught on the box, and the friction between your foot and the surface of the box can cause your body to tilt forward. As a result, you lose your balance.

4. Center of Mass: Your body's center of mass is the point around which your weight is evenly distributed. When you trip and lose your balance, your center of mass might shift outside your base of support (your feet), causing you to tip over and fall.
