What is voltage in plain English?

Voltage is the term used to describe the "pressure" that drives electricity. A voltage is measured in volts (V), and greater voltages result in more electricity flowing to electronic equipment.

What is a voltage in amps?

A "volt," a unit of electric potential, also known as electromotive force, is defined as "the potential difference between two points of a conducting wire carrying a continuous current of 1 ampere, where the power expended between these locations is equal to 1 watt." It appears that there is a one-volt potential, to put it another way.

The time-dependent voltage across the capacitor V(t)=V0 sin(wt)

if the tension on the string is halved and the string is replaced by another with twice the linear density, by what factor will the speed of a wave on the string change?

Answers

The factor by which the speed of a wave on the string change is halved (1/2).

What is a string of mass's tension?

The pull that is designated as tension is in that direction. As a result, the tension will point toward the string or rope and away from the mass. When a mass is hanging, the string pulls it upward, applying an upper force, which causes the tension to be on the upper side.

Tension= T' = 1/2T

Linear density = (m/L) final = 2 (m/L)

Speed of the wave = v => sqrt(T/(m/L)

                            => sqrt(T/2 x 2(m/L) )

TRUE OR FALSE As a projectile rises towards the peak of its trajectory, the vertical acceleration is directed upward; as it falls from the peak of its trajectory, its vertical acceleration is directed downward. Group of answer choices

Answers

As a projectile rises towards the peak of its trajectory, the vertical acceleration is directed upward; as it falls from the peak of its trajectory, its vertical acceleration is directed downward. The correct answer is TRUE.

As a projectile is launched into the air, it initially experiences an upward acceleration due to the force applied to it. This acceleration causes the projectile to move upwards, until it reaches the peak of its trajectory. At the peak, the projectile's velocity in the vertical direction is zero and the acceleration is directed downward due to the force of gravity.

As the projectile falls back towards the ground, it experiences a downward acceleration, causing its velocity in the vertical direction to become negative. This acceleration continues until the projectile lands on the ground.

Answers

It is possible for the person to curl into a ball and start spinning after letting go of the rope. However, it would require some effort to initiate the spinning motion.

What do you mean by motion?

An object changing its position with respect to time is referred to as motion. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed.

As the person is falling, the only force acting on her body is gravity pulling her downward. Therefore, there is no horizontal force acting on her body to cause it to spin. However, if the person were to curl into a ball and then actively start spinning by twisting her body or flailing her arms, she could create a torque, which is a force that causes rotation.

It's worth noting that the spinning motion would not have a significant effect on the person's trajectory of falling into the swimming pool, as air resistance is negligible compared to her weight, and the spinning motion would be quickly dampened by the drag caused by the water resistance.

What is velocity vector?

A velocity vector represents the rate of change of the position of an object. The magnitude of a velocity vector gives the speed of an object while the vector direction gives its direction. Velocity vectors can be added or subtracted according to the principles of vector addition.

Part A: To find the particle's speed at t = 0 s, we need to find the magnitude of its velocity vector. The velocity vector is given by the derivative of the position vector with respect to time. So: v = [tex]\sqrt{( (dx/dt)² + (dy/dt)² )}[/tex]

dx/dt = 36t² - 4t, dy/dt = 24t - 2

Therefore, at t = 0 s: v = [tex]\sqrt{(360^2 - 40)^2 + (24*0 - 2)^2 )}[/tex] = [tex]\sqrt{4}[/tex] = 2 m/s

Part B: To find the particle's speed at t = 5.0 s, we substitute t = 5.0 s into the equation for v: v = [tex]\sqrt{(365.0^2 - 45.0)^2 + (24*5.0 - 2)^2 ) }[/tex]= [tex]\sqrt{(1444)}[/tex] ≈ 38.2 m/s.

Part C: To find the direction of motion, we need to find the angle the velocity vector makes with the positive x-axis. We can use the arctangent function to find this angle: θ = atan(dy/dt / dx/dt)

Therefore, at t = 0 s: θ = atan( (240 - 2) / (360² - 4×0) ) = atan(-2/0) = undefined

Part D: To find the particle's direction of motion at t = 5.0 s, we substitute t = 5.0 s into the equation for θ: θ = atan( (245.0 - 2) / (365.0² - 4×5.0) ) ≈ 64.9 degrees

Answers

The frequency of the 3rd normal mode is 8.4 Hz.

What is frequency?

The frequency of an event is the number of times it occurs each unit of time. It is often measured in hertz (Hz), which is the number of cycles per second.

The frequency of a normal mode in a stretched string is given by the equation:

f_n = (n*v)/2L, where f_n is the frequency of the nth normal mode, v is the wave velocity, L is the length of the string, and n is the mode number.

In this case, the length of the string is 8.2 m, the time it takes for the pulse to return is 0.57 s, the mode number is 3 and we are looking for the frequency of the 3rd normal mode.

We can first calculate the wave velocity, v, by dividing the length of the string by the time it takes for the pulse to return.

v = L/T

v = 8.2 / 0.57

v = 14.4 m/s

Now we can use this value of v to calculate the frequency of the 3rd normal mode:

f_n = (n*v)/2L

f_n = (314.4)/(28.2)

f_n = 8.4 Hz

So, the frequency of the 3rd normal mode is 8.4 Hz.

What is weight of an object?

The force of gravity acting on an object is known as its weight, and it can be calculated using the formula w = mg, which equals the mass times the acceleration of gravity. The newton is the SI unit for weight because it is a force.

How to find the weight of the passenger?

The apparent weight of a 76 kg passenger at the highest point of a circle is the force experienced by the passenger due to gravity and the centrifugal force acting on them.

At the highest point of the circle, the passenger is experiencing the greatest force due to the centrifugal force acting on them. This force acts away from the center of the circle and is equal to the product of the mass of the object and the square of the angular velocity of the circle (w²r) where w is the angular velocity and r is the radius of the circle.

As the apparent weight is equal to the force due to gravity minus the centrifugal force, at the highest point of the circle, the apparent weight of a 76 kg passenger would be equal to their true weight (76 kg) minus the centrifugal force acting on them.

So, to express this in SI units, the apparent weight would be in Newtons (N) and the weight of the passenger is 76 kg * 9.8 m/s^2 = 744.8 N.

To find the total charge moved through the battery in coulombs, we can multiply the number of electrons moved by the charge of one electron:

Q = n * e

where Q is the total charge, n is the number of electrons, and e is the charge of one electron.

In this case, the number of electrons moved through the starter motor is 4.05e21. Therefore:

Q = 4.05e21 electrons * -1.6 x 10^-19 C/electron

Q = -6.48e1 C

The absolute value of this charge is -6.48e1 = 6.48e1 C.

This problem explores the behavior of charge on conductors. We take as an example a long conducting rod suspended by insulating strings. Assume that the rod is initially electrically neutral. For convenience we will refer to the left end of the rod as end A, and the right end of the rod as end B.

Answers

The charge of the same sign will repel as the ball with a negative charge moves toward the A end of the neutral bar, and when they do so, they move to the left end, leaving the rod with a positive charge.

What do you mean by charge?

Charge, also known as electric charge, electrical charge, or electrostatic charge and denoted by the symbol q, is a property of a unit of matter that indicates how many more or fewer electrons than protons it contains.

What does the term "charge" in chemistry mean?

Subatomic particles have a characteristic known as "electric charge" that makes them experience force while in an electric and magnetic field. Positive and negative charges are the two forms of electricity that are often carried by.

What do you think are the factors that might affect the magnitude of this angle

Answers

The bond angle in a compound is the angle formed between two bonds in the compound. It is affected by the geometry, electron cloud and the size of atoms.

What is bond angle ?

Bond angle is the distance between two chemical bonds in a compound. Bond angle is affected by the electrostatic force of repulsion and attraction. Hence, the presence of lone pairs and bond pair are the main factors affecting the bond angle.

If there are lone pairs, the repulsion between two  lone pairs is greater than that between a lone pair and bond pair which in turn greater than that between two bond pairs.

Hence, the electron clouds will align themselves to minimize the repulsion. Thus, the geometry and bond angle may vary from what we predicted based on hybridization.

Read the excerpt below and then answer the question that follows:The Book of DragonsChapter III The Deliverers of Their Country, an excerptBy E. NesbitIt all began with Effie's getting something in her eye. It hurt very much indeed, and it felt something like a red-hot sparkonly it seemed to have legs as well, and wings like a fly. Effie rubbed and criednot real crying, but the kind your eye does all by itself without your being miserable inside your mindand then she went to her father to have the thing in her eye taken out. Effie's father was a doctor, so of course he knew how to take things out of eyes.When he had gotten the thing out, he said: "This is very curious." Effie had often got things in her eye before, and her father had always seemed to think it was naturalrather tiresome and naughty perhaps, but still natural. He had never before thought it curious.Effie stood holding her handkerchief to her eye, and said: "I don't believe it's out." People always say this when they have had something in their eyes."Oh, yesit's out," said the doctor. "Here it is, on the brush. This is very interesting."Effie had never heard her father say that about anything that she had any share in. She said: "What?"The doctor carried the brush very carefully across the room, and held the point of it under his microscopethen he twisted the brass screws of the microscope, and looked through the top with one eye."Dear me," he said. "Dear, dear me! Four well-developed limbs; a long caudal appendage; five toes, unequal in lengths, almost like one of the Lacertidae, yet there are traces of wings." The creature under his eye wriggled a little in the castor oil, and he went on: "Yes; a bat-like wing. A new specimen, undoubtedly. Effie, run round to the professor and ask him to be kind enough to step in for a few minutes.""You might give me sixpence, Daddy," said Effie, "because I did bring you the new specimen. I took great care of it inside my eye, and my eye does hurt."The doctor was so pleased with the new specimen that he gave Effie a shilling, and presently the professor stepped round. He stayed to lunch, and he and the doctor quarreled very happily all the afternoon about the name and the family of the thing that had come out of Effie's eye.But at teatime another thing happened. Effie's brother Harry fished something out of his tea, which he thought at first was an earwig. He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth. There it sat, stroking itself with its feet and stretching its wings, and Harry said: "Why, it's a tiny newt!"The professor leaned forward before the doctor could say a word. "I'll give you half a crown for it, Harry, my lad," he said, speaking very fast; and then he picked it up carefully on his handkerchief."It is a new specimen," he said, "and finer than yours, Doctor."It was a tiny lizard, about half an inch longwith scales and wings.So now the doctor and the professor each had a specimen, and they were both very pleased. But before long these specimens began to seem less valuable. For the next morning, when the knife-boy was cleaning the doctor's boots, he suddenly dropped the brushes and the boot and the blacking, and screamed out that he was burnt.And from inside the boot came crawling a lizard as big as a kitten, with large, shiny wings."Why," said Effie, "I know what it is. It is a dragon like the one St. George killed."And Effie was right. That afternoon Towser was bitten in the garden by a dragon about the size of a rabbit, which he had tried to chase, and the next morning all the papers were full of the wonderful "winged lizards" that were appearing all over the country. The papers would not call them dragons, because, of course, no one believes in dragons nowadaysand at any rate the papers were not going to be so silly as to believe in fairy stories. At first there were only a few, but in a week or two the country was simply running alive with dragons of all sizes, and in the air you could sometimes see them as thick as a swarm of bees. They all looked alike except as to size. They were green with scales, and they had four legs and a long tail and great wings like bats' wings, only the wings were a pale, half-transparent yellow, like the gear-boxes on bicycles.Based on the exposition in the bolded paragraph, what do we know about Effie?
