the primary coil of a transformer has n1 5 350 turns, and the secondary coil has n2 5 2 000 turns. if the input voltage across the primary coil is dv 5 170 cos vt, where dv is in volts and t is in seconds, what rms voltage is developed across the secondary coil?
The rms voltage developed in secondary coil is 971.42 volt.
A transformer is the simplest device used to transfer electrical energy from one AC circuit to another through the process of electromagnetic induction. A transformer either increases AC voltage (step-up transformer) or decreases AC voltage (step-down transformer). Transformers, which are typically used to transmit and distribute AC power, are essentially voltage regulators. Transformers serve a variety of purposes, such as stepping up the voltage of generators to transmit power over long distances, or stepping down the voltage of traditional electrical circuits to power low-voltage devices such as doorbells and toy trains.The term RMS is an abbreviation for Root Mean Square. RMS voltage is defined as the square root of the mean square of the instantaneous value of the voltage signal. The rms value is also called the root mean square. RMS voltage can also be defined as the integral of the square of the instantaneous value during a cycle of continuously varying voltage.

What is the displacement current through a circular loop of radius r = 3.00 cm centered on the axis of the capacitor?
What is the magnitude of the magnetic field between the capacitor plates at a radius r = 3.00 cm from the axis of the capacitor?
Part a: Displacement current: I(d1) = 8 ampere.
Part b: displacement current: I(d2) = 2.812 x 10⁻¹ A.
Part c: magnetic field at a r = 3 cm radial distance: 1.875 x 10⁻⁶ T.
Explain the term Displacement Current?The electric field that exists between both the capacitor plates stores energy in capacitors. A current known as displacement current forms between the capacitor plates if the electric field between them is continuously changing.Part a: Displacement current within the 21 cm-radius circular loop.
Since the capacitance plate has a 16 cm radius, the current can only flow in a loop of this size, or the total displacement current flows within a loop with a 21 cm radius.
Displacement current;
I(d1) = ∈₀.dФ(e)/dt
I(d1) = ∈₀ x A x (Qr.d/∈₀.A.d)
I(d1) = Qr
I(d1) = 8 C/s

I(d2) = Jd x A1
I(d2) = 99.478 x 2.827 x 10⁻³
I(d2) = 2.812 x 10⁻¹ A.
Part c: magnetic field at a r = 3 cm radial distance.
Field of magnetism:
B = μ₀.I(d2) / 2πr
B = 4π x 10⁻⁷ x 2.812 x 10⁻¹ / 2π x 0.03

Using travel time , the distance of wave to epicenter is 7.5 x 10¹⁰m.
Dr. Robert Butler briefly described how to use seismic travel time curves. You can observe P- and S-wave arrivals on a seismogram and calculate how far the earthquake was from your station. A travel time curve is a plot of arrival times, usually of a P or S wave, recorded at various points as a function of distance from the seismic source. Seismic velocities in the ground can be calculated from the slopes of the resulting curves.A seismic wave traveling through an isotropic homogeneous medium will propagate at a constant speed. Thus, the time required for a seismic wave to travel from source to receiver in a homogeneous earth layer with velocity is simply given by the formula t=d/v , where is the distance traveled in the layer. In a seismic survey, we measure the travel times between the source and the receiver and use this data to estimate the properties of the subsurface.

What kinds of energy are required by endurance athletes?
For endurance sports, carbohydrates are frequently the preferred fuel source, so they take center stage in many athletes' nutrition programs. An additional source of carbohydrates is typically necessary to maintain peak performance because the body burns through its glycogen reserves, even at a pace below maximum

the worker's pull on the handle of the cart can best be described as a force having a a horizontal component , only b a vertical component , only c a horizontal and a vertical component d no directional component
The worker's pull has both the horizontal and the vertical component that is : both magnitude and direction.
Why would the force have horizontal and vertical component ?Draw the force vector graphically, then a horizontal and vertical line that forms a right triangle. It is possible to measure the connections between the horizontal and vertical lines graphically or alternatively by computation.
In mechanics, horizontal and vertical components are frequently seen.
Two forces that are mutually perpendicular to one another can be used to break down a force acting in one direction into its component parts.
Thus we will get the two components the vertical component being the N that is normal and the horizontal component is f = friction.

The reactivity phenomenon of self-monitoring procedures has been shown to
O increase desired behaviors,
O decrease undesired behaviors.
O both increase desired behaviors and decrease undesired behaviors.
O neither increase desired behaviors nor decrease undesired behaviors.
The reactivity phenomenon of self-monitoring procedures has been shown to Option C:both increase desired behaviors and decrease undesired behaviors.
Self-monitoring, a term coined by Mark Snyder in the 1970s, refers to the degree to which individuals keep an eye on how they come across, how they act expressively, and how they act emotionally nonverbally. According to Snyder, human beings generally differ significantly in their capacities and motivations for engaging in expressive controls (see dramaturgy).
Self-monitoring is a personality feature that is used to describe the capacity to control conduct to meet social circumstances. In order to assure proper or desired public appearances, people who are concerned with their expressive self-presentation (see impression management) prefer to pay great attention to their audience. Self-monitors make an effort to comprehend how other people and groups will view their behaviour. Some personality types commonly act spontaneously (low self-monitors) and others are more apt to purposely control and consciously adjust their behavior (high self-monitors).

(R1/R2)V1 is its speed at its farthest distance.
The rate of change in position of an object in any course.Speed is measured because the ratio of distance to the time wherein the distance became included. Speed is a scalar amount because it has handiest route and no significance.
Velocity can be notion of as the rate at which an object covers distance. A quick-moving object has a high speed and covers a notably big distance in a given amount of time, whilst a sluggish-shifting item covers a relatively small amount of distance in the same amount of time.
The primary unit or the S.I. unit of velocity is m/s or ms?¹.
