Final answer:

The electrostatic force between two charges increases by a factor of 16 when the distance between them is reduced to a quarter of the original distance, resulting in a new force of 16 N.

Explanation:

The question provided deals with the concept of electric force between point charges, which is described by Coulomb's Law. According to this law, the force F between two point charges is directly proportional to the product of the charges q₁ and q₂, and inversely proportional to the square of the distance r between them. Specifically, F = k * (q₁ * q₂) / r², where k is Coulomb's constant.

In the original scenario, two charges exert a 1.0-N force when separated by a distance of 1.0 meters. When the separation is reduced to 1/4 meter (or 0.25 meters), the distance squared term in Coulomb's Law (r²) becomes (0.25)², which is 1/16 of the original distance squared. Since the force is inversely proportional to the square of the distance, decreasing the distance by a factor of 4 (which squares to be a factor of 16) increases the force by that same factor of 16.

Thus, the new force would be 1.0 N multiplied by 16, resulting in a force of 16 N when the charges are 1/4 meter apart.

The correct choice is Buffers.

Buffers contains both acids and bases in equilibrium.when base is added to buffers, they adjust the pH value by releasing hydrogen ions.when acid is added to buffers, they adjust the pH value by consuming hydrogen ions. hence these substances resist any change in their pH value by releasing or absorbing hydrogen ions.This process keeps the pH value constant.

Answer:

Partially: From C to D, kinetic energy is transformed into gravitational potential energy and From D to E, gravitational potential energy is transformed into kinetic energy

Explanation:

What happens in this pendulum is that at point A, there's only gravitational potential energy (no velocity=no kinetic energy)

At point C, it has maximum speed since all of the potential energy is transformed into kinetic energy (no potential gravitational  energy at this point)

At point E, it is the same as at point A. (no kinetic energy)

At the intermediate points (B and D) there are both kinetic and potential energy. At point B the kinetic energy is increasing and at point D it is decreasing.

Now let's see each case:

- From A to C, kinetic energy is transformed into gravitational potential energy: It is actually the opposite, so no.

- From C to D, kinetic energy is transformed into gravitational potential energy: Yes, but not all of it is transformed since it still has kinetic energy that allows it to get til point E.

- From C to E, gravitational potential energy is transformed into kinetic energy: No, it is the opposite.

- From D to E, gravitational potential energy is transformed into kinetic energy: Yes, but not all of it, since at point D it also has kinetic energy.

The kinetic energy is transformed into gravitational potential energy from point C to B. But complete transformation is not happening. Thus, the statement is somehow correct.

The analysis of pendulum is given as follows:

Now as per the given statements:  

Thus, we can conclude that from C to D, the kinetic energy is transformed into gravitational potential energy, but the transformation is not complete. Hence, statement (B) is correct.

According to Charles's law, the volume of a fixed amount of gas is directly proportional to its Kelvin temperature, assuming constant pressure. It means that volume of the gas increases with increase in temperature and decreases with decrease in temperature.

According to Charles's law, the volume of a fixed amount of gas is directly proportional to its Kelvin temperature when the pressure is held constant. This law was named after the French scientist Jacques Alexandre César Charles, a pioneer in balloon flight. It essentially means that when the temperature of gas increases under constant pressure, the volume of the gas also increases and vice versa.

For instance, if you raise the gas temperature from 283 K to 303 K at a constant pressure, you will see an increase in its volume from 0.300 L to 0.321 L, corroborating Charles's law.

Answer:

V = 1.66 L

Explanation:

As we know that at the depth of 10 m the volume of the lungs of diver is given as

V = 2.40 L

Temperature = 32 degree C

Pressure = 101.30 kPa

Now we have change the values of pressure and temperature

Pressure = 141.20 kPa

Temperature = 21 degree C

Now we can use idea gas equation to solve this

[tex]PV = nRT[/tex]

[tex]\frac{P_1V_1}{RT_1} = \frac{P_2V_2}{RT_2}[/tex]

so we have

[tex]\frac{101.30 \times 2.40}{R(273 + 32)} = \frac{141.20 \times V}{R(273 + 21)}[/tex]

[tex]V = 1.66 L[/tex]

The correct current value is 1.35 A.

The correct current value in the 0.5 dcma position can be determined using the given information. According to the information provided in the question, after 5.00 ms, the current declines to 0.368 of the initial value at t=0. Therefore, we can find the initial value of the current by dividing the value at t=5.00 ms by 0.368. Let's calculate:

Initial current = (0.368)(3.68 A) = 1.35 A

So, the correct current value if the selector is in the 0.5 dcma position is 1.35 A.

Answer:

Gravity

Explanation:

The weight of a person is given by :

W = m g

Where

m is the mass of the person

g is acceleration due to gravity.

Weight of the person depend on the value of acceleration due to gravity. The mass of the person remains the same in every location. On the surface of earth it is equal to 9.8 m/s². While on surface of sun it is equal to 274 m/s².

Hence, a person on earth would weigh a lot more on the sun due to increased gravity.

A gas does work by changing its volume, adhering to the law of conservation of energy and resulting in increases in energy, pressure, and/or temperature.

A gas can do work by changing its volume. When a gas in a cylinder expands, it exerts a force on the piston and moves it, doing work. According to the Ideal Gas Law, work done by a gas results in an increase in its energy, which can manifest as an increased internal kinetic energy due to the motion of its atoms and molecules. This concept adheres to the law of conservation of energy, meaning that energy within a closed system is neither created nor destroyed, but can change forms. An example of work being done by a gas is when you inflate a bicycle tire; the air pressure and temperature increase inside the tire due to the work done by the pump.

Thus, the correct answer to how a gas does work is A. By changing volume.

Final answer:

A skydiver in free fall describes constant acceleration in one direction since gravity provides a constant acceleration downwards near Earth's surface.

Explanation:

The question asks which scenario describes constant acceleration in one direction. The correct answer is a skydiver in free fall. This is because, near the surface of the Earth, an object in free fall experiences a constant acceleration due to gravity, with a magnitude of approximately 9.8 m/s².

The direction of this acceleration is vertically downwards, and it remains constant in both magnitude and direction in the absence of air resistance.

In contrast, a car rounding a bend, a merry-go-round increasing speed, or a pendulum swinging all experience changing directions or types of motion which do not represent constant acceleration in one direction.

C

Explanation:

Final answer:

The tension in the rope is 516 N.

Explanation:

To find the tension in the rope, we need to calculate the net force acting on the sled. The net force is equal to the mass of the sled multiplied by its acceleration. Given that the sled has a mass of 72 kg and accelerates at 2 m/s² for 5 seconds, we can use the equation:

Net force = mass x acceleration

Net force = 72 kg x 2 m/s² = 144 N

However, there are two forces acting in the opposite direction - the force of friction (120 N backwards) and the drag force (540 N backwards). So, the net force is:

Net force = 144 N - 120 N - 540 N = -516 N

The negative sign indicates that the net force is acting in the opposite direction of motion. Therefore, the tension in the rope is equal in magnitude and opposite in direction to the net force, so the tension in the rope is 516 N.
