In what part of the electromagnetic spectrum does the sun radiate maximum energy? How does this compare to earth?

Answers

Answer 1

The visible region of the electromagnetic spectrum is where the Sun radiates maximum energy. Since Earth is substantially cooler, the majority of the radiation it emits is longwave radiation.

The complete spread of electromagnetic radiation by wavelength or frequency. Despite the fact that all electromagnetic waves have a wide range of frequencies, wavelengths, and photon energies, they all move at the speed of light in a vacuum known as the electromagnetic spectrum.

The sun emits electromagnetic waves over a wide spectrum, from radio waves with a wavelength of 10 meters to X-rays with a wavelength of 2 nanometers. Visible light, with a wavelength of around 500 nanometers, is the most powerful of them to reach the earth's surface. The visible spectrum is where the Sun's energy is most intensely emitted. The maximum amount of radiation that the Earth emits occurs at 10 mm, in the infrared heat spectrum. Since the Earth's surface temperature is far lower than that of the sun and its radiation has longer wavelengths than solar radiation, the majority of this energy is then reradiated into space. The atmosphere is easily able to absorb the longer wavelengths that the Earth radiates.

The fixed assets turnover ratio of gd products is 13. 6 and that of its competitor, ap goods inc. , is 6. 0. what does this financial data primarily imply?

Answers

The correct answer is GD Products collects receivables more quickly than AP Goods.

Analysts typically utilize the fixed asset turnover ratio (FAT) to gauge operating performance. This efficiency ratio assesses a company's capacity to generate net sales from its fixed-asset investments, specifically property, plant, and equipment (PP&E). It compares net sales (income statement) to fixed assets (balance sheet) (PP&E). Utilized as a net of accumulated depreciation is the fixed asset balance. A greater fixed asset turnover ratio shows that a business has utilized fixed asset investments to drive sales effectively. A greater ratio suggests that management is making better use of its fixed assets. No information can be gleaned from a high FAT ratio about a company's capacity to produce reliable earnings or cash flows.

Energy density is defined as the amount of energy accumulated in a system per unit volume. In the case of electrical energy. Electrical energy density = permittivity* Electric field squared/2 mu0

When an electric current is passed through a current-carrying circular wire loop, the magnetic field lines are generated in a circular pattern around the arms of the coil while the magnetic field lines are straight at the center of the loop

The magnetic field strength at the center of a circular loop is given by

You are looking straight into the front of an aquarium. you see a fish off to your right. is the fish actually in the direction you’re looking, farther to the right, or farther to the left? explain.

Answers

The you see a fish off to your right is actually farther to the left in the direction you’re looking due to refraction of light.

What is refraction of light?

Refraction of light is the bending of light rays as the cross the boundary between two media of different densities.

When light travels from a less dense to a denser medium, the ray of light is bent closer towards the normal. However, when the ray of light is travelling from a denser to a less dense medium, the ray of light is bent away from the normal.

Considering the situation in seeing a fish through an aquarium. Light rays from the water which is less dense than air travels to the eyes and is bent away from the normal. Therefore, the fish seen straight ahead is actually, farther to the left.

In conclusion, refraction of light causes the apparent change in the position of the fish.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity.

The scalar product of two vectors is the sum of the product of the corresponding components of the vectors. In other words, the scalar product is equal to the product of the magnitudes of the two vectors and the cosine of the angle between them. It is a scalar quantity and is also called the dot product of vectors.

if | a + b | > |a| or |b|

a. b = |a| |b| cos (theta)

since , | a + b | > |a| or |b|

hence, angle between a and b must be less than 90°

If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?.

Answers

Answer:

The voltage remains constant.

Answer:

The voltage in the circuit remains same. However the current drawn by the circuit will increase.

Explanation:

According to Ohm's Law:

V=IR

If we halved the resistance let:

R'=R/2

then

I'=2I in order to kept the Voltage same. Also the resistance is the opposition to the current. So, if resistance will halved then obviously current will double

So when we put these value in to Ohm's Law the results is:

V'=I'R'

V'=2I(R/2)

V'=IR which is equal to first voltage. Hence,

V'=V

The direction of the net electric force that acts on an electric charge at every point of an equipotential surface created by other charges must be?

Answers

The direction of the net electric force that acts on an electric charge at every point of an equipotential surface created by other charges must be perpendicular to the surface.

A surface with an equipotential potential is one where all points on the surface have the same electric potential. This means that at every point on the equipotential surface, a charge will have the same potential energy.

The repulsive or attractive interaction between any two charged bodies is called as an electric force. Similar to any force, its impact and effects on the given body are described by Newton's laws of motion. The electric force is among the list of other forces that exert over objects.

On an equipotential surface , the potential difference between any two points is zero. So , the work done by the electric field on a test charge moving on the surface will be zero. Therefore , the electric field must be perpendicular to the surface at every point . Hence electric force must have the same direction , that is perpendicular to the surface.

Answers

The inductance of the inductor is 35.8 mH.

What is inductance?

Inductance, which would be defined as the proportion of voltage to current change rate, is what distinguishes an inductor from other electrical devices. The magnetic field induced on the coil causes inductance. The coil's form is one of the many elements that affect it.

Calculation:

Provided that,

voltage = 120 V

frequency = 1000Hz

capacitor (C) = 2.00μF

current = 0.680 A

We have to find out the inductance of that inductor by using the formula of the current,

I = V/Z

Z = [tex]\sqrt{R^{2} +(Lw - \frac{1}{Cw)^{2} } }[/tex]

Now putting the value of Z into this equation we get:

I = [tex]\frac{V}{\sqrt{R^{2}+(Lw - \frac{1}{Cw})^{2} } }[/tex]

(d) The gravitational force parallel to the plane is 17.1 N.

(e) The block will not slide after being placed on the incline since the parallel force is less than the maximum static frictional force.

(f) The acceleration will be in the direction of the static frictional force.

The given parameters in the question;

Weight of the metal block, W = 50 NInclination of the plane, θ = 20⁰Coefficient of static friction, μs = 0.5Coefficient of kinetic friction, μk = 0.3

Mass of the block

The mass of the block is calculated as follows;

W = mg

where;

g is acceleration due to gravity

m = W/g

m = (50) / 9.8

m = 5.1 kg

Magnitude of the normal force of the block

Fₙ = mg cosθ

Fₙ = W cosθ

Fₙ = 50 x cos(20)

Fₙ = 46.98 N

Maximum static frictional force between the block and the incline

Fs = μs(Fₙ)

Fs = 0.5 x 46.98 N

Fs = 23.49 N

Gravitational force parallel to the plane

F = W sinθ

F = 50 x sin(20)

F = 17.1 N

Net force on the metal block

F(net) = F - Fs

F(net)  = 17.1 N - 23.49 N = -6.39 N

Thus, the block will not slide after being placed on the incline since the parallel force is less than the maximum static frictional force.

Acceleration of the block after being placed on the incline
