if you triple the distance between two point charges, by which factor does the force between the particles change?

The net force would cause the velocity of the body to change and it would accelerate.

We know that the force that is acting on a body is a vector quantity. If the force is a vector quantity, the implication of this is that the force would have both a magnitude and direction.

According to the Newton first law of motion, if an object is acted upon by an unbalanced force, the result of this is that the velocity of the object would change and the object would accelerate.

This leads us to the conclusion that if an object of mass "m" weighs "mg," then an object of mass "2m" weighs "2mg."

Mass is a crucial aspect of all matter and a measurement on inertia in physics. What a body of matter is fundamentally, is the resistance it offers to something like a change in its speed and location brought on by the application of a force. The amount of mass a body has no bearing on how much of a change a force applies.

Mass is a unit used to describe the amount of matter who makes up an object. Weight, a measure of force, is used to calculate the gravitational pull an object experiences. In contrast to mass, weight is not location-dependent.

The speed of the satellite at perigee is 7074.27 m/s

What is satellite?
An object that has been placed into orbit in space on purpose is known as a satellite as well as artificial satellite. Most satellites, with the exception of passive satellites, have a means of generating electricity for the equipment they carry, such as solar panels as well as radioisotope thermoelectric generators (RTGs). The majority of satellites also have transponders, which are a type of ground station communication system. The most common satellites, small CubeSats, use a standardised bus to reduce costs and labour. Satellites of a similar type can cooperate with one another to form constellations. Satellites are made to be as light and durable as possible due to the high cost of space launch. Numerous transponders, with a bandwidth of dozens of megahertz, are carried by the majority of communication satellites, which are radio relay channels in orbit.

The speed of the satellite at perigee can be calculated using the equation of conservation of energy:
e = (½) mv2 - G(Mm/r)

Where e is the total energy of the satellite, m is its mass, v is its velocity, G is the gravitational constant, M is the mass of the Earth, and r is its distance from the Earth's center.

At apogee, the total energy of the satellite is:
e1 = (½) mv12 - G(Mm/r1)

At perigee, the total energy of the satellite is:
e2 = (½) mv22 - G(Mm/r2)

Equating the two expressions, we get:
(½) mv12 - G(Mm/r1) = (½) mv22 - G(Mm/r2)

Substituting the given values, we get:
(½)(6260 m/s)2 - G(Mm/2500 km) = (½) mv22 - G(Mm/500 km)

Rearranging the equation, we get:

mv22 = (½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)

Taking the square root of both sides, we get:
v2 = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)]

Finally, we get:
v = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)]

Therefore, the speed of the satellite at perigee is:
v = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)] ≈ 7074.27 m/s

The position versus time plot of driven harmonic motion when the driving frequency is slightly higher than the theoretical natural frequency will show a sinusoidal oscillation with a gradually increasing amplitude.

What is harmonic?
A harmonic wave, like a sinusoidal wave, has a frequency that is an integer multiple of the basic frequency, or the frequency of the initial periodic signal. The first harmonic of the original signal is also referred to as that; higher harmonics are the other harmonics. The sum of harmonics is periodic at the fundamental frequency because all harmonics are at that frequency as well. A harmonic series is formed by the group of harmonics.

The phrase is used in a variety of fields, including radio technology, physics, acoustics, power electronics transmission, and music. For instance, if indeed the frequency response is 50 Hz, which is a typical AC power supply frequency, the first three higher harmonics' frequencies are 100 Hz (second harmonic), 150 Hz, and 200 Hz (3rd harmonic).

As the driving frequency increases, the amplitude of the oscillation will become more pronounced and eventually reach a peak before decaying back to the original amplitude. The period of the oscillation will remain constant, even as the amplitude increases.

Magnitude of current required is 1630 amp.

Current can be defined as the rate of flow of charge.

Since Faraday represents the magnitude of electric charge per mole of the electron

Mass can be given as:

mass = molar mass * faradays used/faradays needed

1 faraday = 1C/96500

Na + (aq) + e- -> Na(s) : one electron is transferred so faradays needed to produce 23.0g Na is 1

1.4kg*1000 = 1400g

1400g = 23.0g/mol * Fu/1f

Fu (faradays used) = Coulombs/96500 (faraday constant)

Fu = 60.9f=Q/96500

Q = 96500*60.9= 5.88*10^6

Question is incomplete the complete question is:

A student runs an experiment in which a block of known mass is moving across a horizontal table in an xy-coordinate plane. As the block reaches the origin of the coordinate system, the block explodes into two pieces of masses m1 and m2. During the experiment, the velocity of the block 1.0 second before the explosion and the velocity of the two pieces 1.0 second after the explosion are measured using a motion sensor. Conservation of momentum is applied using the masses of the two pieces. However, when the velocity of the piece of mass m2 is calculated, the measured value is 10% less than the calculated value. Which of the following statements best explains the difference in the calculated and measured velocity?

A) As the block is moving across the table, friction will affect the block’s motion and thus could account for the difference.

B) It is possible that a small amount of the original block was lost during the explosion.

C) When the student did the calculation, the student assumed that the explosion occurred just as the block reached the origin. The difference in velocity could be due to the explosion occurring either just before or just after the origin.

D) The explosion created a force that affected the experiment.

E) Conservation of momentum is not the correct equation to apply to the explosion, since the two pieces apply forces to each other.

The correct explanation will be as the block is moving across the table, friction will affect the block’s motion and thus could account for the difference.

What is friction?

Moving things lose energy and slow down due to the friction force that resists their motion. A fluid, like air or water, exerts a frictional force on moving objects when they travel through it. A fluid's frictional force is referred to as a drag force.

To calculate the pressure in the car tires, we can use the equation $P = \frac{F}{A}$, where $P$ is the pressure, $F$ is the force acting on the area, and $A$ is the area over which the force is applied. In this case, the force acting on the tire is the weight of the car, and the area is the portion of the tire that is in contact with the road.

First, we need to calculate the weight of the car. The weight of the car is given by the equation $W = mg$, where $m$ is the mass of the car and $g$ is the acceleration due to gravity. We are given that the mass of the car is 1700 kg, so the weight is $W = 1700 \text{ kg} \times 9.8 \text{ m/s}^2 = 16786 \text{ N}$.

Next, we need to calculate the force acting on each tire. Since the weight of the car is distributed evenly among the four tires, each tire supports one-fourth of the total weight, or $F = \frac{1}{4} \times 16786 \text{ N} = 4196.5 \text{ N}$.

Now we need to calculate the area of the tire that is in contact with the road. The width of the tire is 16 cm, and we are given that two-thirds of the flattened bottom segment is in contact with the road.

This means that the length of the segment in contact with the road is $\frac{2}{3} \times 15 \text{ cm} = 10 \text{ cm}$. The area of the tire in contact with the road is therefore $A = 16 \text{ cm} \times 10 \text{ cm} = 160 \text{ cm}^2$.

Finally, we can use the equation $P = \frac{F}{A}$ to calculate the pressure in the tires. Plugging in the values for the force and the area, we get

$$P = \frac{F}{A} = \frac{4196.5 \text{ N}}{160 \text{ cm}^2} = 26.2 \text{ Pa}$$
