coulomb force into newton's second law and solve for the acceleration. what is the algebraic representation of the acceleration of the disc? your answer should

q1 and q2 are the charges of the two discs, m is the mass of a disc, and r is the distance between the discs. epsilon_0 is the electric permittivity of free space.

Electric permittivity, also known as the dielectric constant, is a measure of how easily an electric field can pass through a material.

The algebraic representation of the acceleration of the disc is given by the following expression:
a = (q1*q2)/(4*pi*epsilon_0*m*r^2)
This expression is derived from Newton's Second Law, which states that the net force is equal to the mass of the object multiplied by its acceleration, F = ma. The net force in this case is the Coulomb force between the two charged disks, which is given by the expression F = (q1*q2)/(4*pi*epsilon_0*r^2). Substituting this expression into Newton's Second Law, we can solve for the acceleration: a = (q1*q2)/(4*pi*epsilon_0*m*r^2).
Here, q1 and q2 are the charges of the two discs, m is the mass of a disc, and r is the distance between the discs. epsilon_0 is the electric permittivity of free space.

Answer:

-28.3°.

Explanation:

To find the direction of the sum of two vectors, we can use the head-to-tail method. This involves placing the tail of one vector at the head of the other vector and drawing a vector from the tail of the first vector to the head of the second vector.

Given the vectors: 3.14 m B 30.0° -60.0° 2.71 m

We can find the x and y components of the vectors first:

Vector 1: 3.14 m B 30.0°

x-component: 3.14 m * cos 30.0° = 2.67 m

y-component: 3.14 m * sin 30.0° = 1.57 m

Vector 2: -60.0° 2.71 m

x-component: 2.71 m * cos -60.0° = -1.36 m

y-component: 2.71 m * sin -60.0° = -2.12 m

To find the sum of the vectors, we add their x-components and y-components

x-component = 2.67 m + (-1.36 m) = 1.31 m

y-component = 1.57 m + (-2.12 m) = -0.55 m

The direction of the vector is the angle that the vector makes with the positive x-axis, so we can use the arctan function to find the angle:

Direction = arctan(y-component/x-component) = arctan(-0.55/1.31) = -28.3°

So the direction of the sum of the vectors is -28.3°.

The magnitude of the electric field along the long axis of the rod at a point 27.0 cm from its center is -4,444,444 N.

When charge is present in any form, each point in space has an electric field that is connected to it. The value of E, also known as the electric field strength, electric field intensity, or just the electric field, is used to express the size and direction of the electric field.

A charged rod's electric field can be calculated using the following formula:

E (electric field ) = k Q/[D (D + L)]

Where,

E is electric field

k is Coulomb’s constant = 9×10⁹ Nm²/c²

Q is  total charge = -20.0 µc = -20.0 × 10⁻⁶c

L is length of rod = 12.0 cm = 0.12 m

D is distance from the center = 27.0 – 12.0 cm = 0.15m

Substituting the values in the formula:

E = (9×10⁹ Nm²/c²) × (-20.0×10⁻⁶c) / [0.15m (0.15m + 0.12m)]

E = -4,444,444 N.

The gauge pressure of the water at the pump 10.96 Pa.

Gauge pressure is a type of pressure measurement that is relative to atmospheric pressure. It is calculated by taking the absolute pressure of a system and subtracting the atmospheric pressure from it. Gauge pressure is often used to measure the pressure of a closed system, like a tire or an air conditioning unit, because it is easier to measure than absolute pressure.

The pressure at the pump is equal to the difference in height between the pump and the nozzle multiplied by the acceleration due to gravity (9.8 m/s2) plus the kinetic energy of the water in the hose. The kinetic energy is equal to the velocity of the water squared, divided by two.

So the pressure at the pump is:
Pump Pressure = (1.00 m * 9.8 m/s2) + (0.400 m/s)2 / 2
Pump Pressure = 9.8 + 0.160

Image separation approximately -7.75 cm. The above mirror's focal length measures -10.33 cm.

The focal length of your camera seems to be the range (in millimeters) between its point of convergence and the sensor or film used to capture the image. How much of a scene that camera can record depends on the telephoto lens of a films or internet camera lens.

The maximum aperture of the lens, which is often given in millimeters, is really the length between the perspective and the sensor when the image is in focus. The minimal and maximum lens lengths of telephoto lenses are specified, for instance, 18-55 mm.

magnification = image / object

It would take 1.449 ns (newton-second) for a signal to travel one-meter length of the coaxial cable filled with lossless Teflon.

The speed of light is a fundamental constant of physics that represents the fastest possible speed at which energy, matter, and information can travel in a vacuum. The speed of light is approximately 299,792,458 meters per second, or about 670,616,629 miles per hour.

The speed of an electromagnetic wave in a medium is given by the equation:

c is equal to 1 / sqrt (mu*epsilon r).

where c is the speed of light in a vacuum, mu_r is the relative permeability of the medium, and epsilon_r is the relative permittivity of the medium.

In this case, the medium is lossless Teflon, which has a relative permittivity of 2.1, and a relative permeability of 1 (since Teflon is nonmagnetic). Therefore, the speed of a signal in the cable is:

c = 1 / sqrt (1 * 2.1)

c = 1 / sqrt (2.1) = 1 / 1.447 = 0.69

The speed of signal in the coaxial cable is 0.69 times the speed of light in a vacuum.

To determine the time, it would take for a signal to travel one-meter length of the cable, we can divide the distance by the speed:

t = d / c

t = 1m / (0.69 * c)

t = 1.449 ns

When you switched from elastic material to string, the effect is that the elasticity of the two materials is different because impulse is a physical vector quantity defined as the product of the average force applied to a body and the time interval. Impulse can also be defined from the variation in the amount of movement suffered by a body.

The use of a stiffer or tighter elastic material caused the duration of the impulse to be shorter, making the maximum force larger. The general rule that can be established is that the force required to produce the same impulse increases with decreasing time.

d-total = 60 m + 180 m = 240 m

The force the book exerts on the table is downward-directed and equal to its weight, which is 25 N.

According to Newton's third law, every force an object A applies to an object B is balanced out by an equally strong force applied in the opposite direction to object A.

The book is object A in this instance, while the table is object B. According to Newton's third law, the table pulls on the book with a force that is both equal to and opposite to that of the force exerted by the table.

The process of any quantity or measure repeatedly varying around its equilibrium value in time is referred to as oscillation. Another way to describe oscillation is as a periodic change in a substance's value between two values or around its midpoint.

1)The pendulum's period is the length of time it takes for one full revolution to occur.

Keep in mind that a pendulum's period is denoted by the following:

T = 2pi√(L/g)

Here, we know that  L = 11.4m

The pendulum's period will then be:

T = 2×3.14×√(11.4m/9.8m/s²) = 6.28×√1.14

T = 6.28×1.06 = 6.65s

So one complete oscillation takes 6.65seconds.

We are aware that the pendulum swings at 8:00 am.

Four hours after the pendulum begins to swing, or 12:00 noon, is the time we're interested in.

So, we're interested in finding out how many full oscillations occur in a period of 4 hours.

It takes 6.65 seconds for each oscillation.

The product of the total time (4 hours) and the period will yield the total number of oscillations.

First, since 1 hour equals 3600 seconds, we must write both of these in the same units.

then,

4 hours = 4(3600 seconds) = 14,400 s

There were a total of: oscillations during that period,

N = 14,400s/6.65s = 2165.41

N = 2165

The pendulum does 2165 oscillations between 8:00 am and 12:00 noon.

2) Amplitude x(t) = A exp (-bt/2m)

x(t) = 1.7 exp (0.010(4(3600/1)))/2(110)
