four amperes of current exist in the primary coil of a transformer. the voltage across the primary coil is 120 v. what is the power output of the secondary coil?

Answers

Answer 1

480 W  is the power output of the secondary coil.

primary  coil current = ip = 4A

primary coil  voltage = vp = 120v

power out put of secondary coil

p = vi

   = 120v * 4A = 480W.

What is power?

Power is the amount of work completed in a given amount of time. Watt (W), which is derived from joules per second (J/s), is the SI unit of power. Horsepower (hp), which is roughly equivalent to 745.7 watts, is a unit of measurement sometimes used to describe the power of motor vehicles and other devices.

The rate at which work is performed on an object is referred to as its power. Power is a temporal concept. It has to do with how quickly a task gets completed. The power equation is described below.

Power = Time + Work

P = W / t

The standard metric unit for power is a Joule/second, which is defined as the product of the standard metric units of work (the Joule) and time (the second).

humans evolved in earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure. because the differences between internal body pressures and atmospheric pressure are so small, individuals have a difficult time gauging the magnitude of atmospheric pressure. suppose an individual is lying on his stomach with sheets of paper stacked on his back. if each sheet of paper has a mass of 0.004400.00440 kg and is the standard letter size of 8.5 in8.5 in by 11 in11 in ( 0.216 m by 0.279 m0.216 m by 0.279 m ), how many sheets must be stacked to produce a pressure on his back equal to atmospheric pressure (roughly 101325 pa101325 pa )?

Answers

A total of 151988 sheets of paper are required to be put on the individual so that it create a pressure of 1 atm.

We know that the pressure is given by the force applied on the area divided by the magnitude of the area.

Here, it is given that dimensions of the paper is 8.5 inch X 11 inch.

So the area of the paper is 93.5 in².

Converting inch square into metre square,

Area = 0.06m².

The mass of 1 sheet of paper is 0.004 kg.

So the force applied by the sheet of paper on the person will be equal to,

F = 0.004 × 10

F = 0.04 N.

Let us say that n number of sheets are required.

The pressure that is needed to be created is 101325 pascals.

Now,

Pressure = force/area

Putting the values,

101325 = N(0.04)/0.06

N = 151988.

So, total of 151988 sheets are required.

surface waves are caused primarily by what? question 6 options: frictional forces between wind and the ocean surface frictional forces at the level of the thermocline layer primarily gravitational forces of the moon large aquatic organisms breaching the ocean surface

Answers

Frictional forces between wind and the ocean surface are the primary cause of surface waves. This is the first option.

How are surface waves formed?

The most common cause of waves is wind. Surface waves, also known as wind-driven waves, are formed by the frictional forces between wind and surface water. The continual disturbance creates a wave crest as wind blows across the surface of the ocean or a lake. Surface waves are found globally across the open ocean and along the coast.

There is also a type of waves called tidal waves. Tidal waves are caused by the gravitational pull of the Sun and Moon on Earth.

You throw a ball straight forward with a velocity of 20
m/s, from a height of 1 meter. How far will it be when it hits the ground after 0.45 seconds?

Answers

The ball will continue to advance at a speed of 2.0 m/s once it rolls off the edge of the table until it lands on the ground after 0.45 seconds.

Why do we do it?

The ball is behaving just like it has been dropped. Nature is unconcerned by the fact that it is also advancing.

D=1/2gt2 and T=√2d/g

By entering the table's height and the gravitational acceleration, we can calculate the time in seconds:

t= √2(1.5m)/9.8m⋅s−2 = 0.553s

So, for a little bit longer than a half-second, the ball will be in the air (and thus able to move ahead). To find the distance travelled, we simply reverse the speed equation, s=dt, and insert in the speed and time:

Answers

The distance to the ink mark appear to be in 3.58cm.

How do you define refractive index?

The refractive index, also known as the index of refraction, is a numerical value that is determined by comparing the difference between the speed of light in a vacuum and that of light in a material with a higher density. The refractive index variable is most usually represented by the letter n or n' in mathematical computations and descriptive language.

The measurement of how much a light ray bends when moving from one medium to another is called the refractive index. It is also known as n = c/v, which is the ratio of the speed of a light beam in a substance to that of a light ray in a vacuum.

The perceived depth of the link noted = real depth/µ

The perceived depth of the link noted  = 3/1.67

5:6 is the ratio of linear speed of two runners in jogging. The rate at which an object's position changes in relation to a frame of reference is known as its velocity, and it depends on time.

What is velocity?

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity.

The primary indicator of an object's position and speed is its velocity. It is the distance that an object travels in one unit of time. The displacement of the item in one unit of time is the definition of velocity.

The speed of the person one at the radium is v1=15

The speed of the person two at the radium is v2=18

The ratio be 15:18  , The 15 and 18 are the common multiple of 3

Therefore 5:6

The rate at which an object's position changes in relation to a frame of reference is known as its velocity, and it depends on time. A specification of a thing's speed and direction of motion is what velocity is.

which combination of neurological imaging techniques contains two methods that utilize magnetic imaging?

Answers

MRI and FMRI are the  combination of neurological imaging techniques contains two methods that utilize magnetic imaging.

A magnetic field and radio waves produced by a computer are used in the magnetic resonance imaging (MRI) medical imaging procedure to provide precise images of the organs and tissues inside your body.

Large, magnetized tubes are the common shape of MRI equipment. The magnetic field briefly realigns water molecules in your body as you lie within the MRI machine. To produce cross-sectional MRI pictures, which resemble the slices of a loaf of bread, radio waves induce these aligned atoms to emit tiny signals.

Your doctor can evaluate your organs, tissues, and skeletal system with an MRI without performing any intrusive procedures. It generates detailed images of the body's.

A resistor, an inductor, and a capacitor are connected in series to an ac source. What is the phase angle between the voltages of the inductor and capacitor in this rlc circuit?.

Answers

The phase angle between the voltages of the capacitor and inductor in rlc circuit is 180°.

The phase angle is the component of a periodic wave. It is the shift between the AC current and the voltage on the measured impedance. The two elements of phase angle are reactance(X) and resistance (R).

The phrase for phase angle is, Xₐ = sinωt

where Xₐ= phase angle

ω = wavelength of the wave in 1 revolution

t = time period of 1 revolution

The instantaneous voltage ΔvR is in phase with the current, ΔvL leads the current by 90°, while ΔvC lags behind the current by 90°. The instantaneous values of these three voltages do add algebraically to give the instantaneous voltages across the RLC combination.
