magnetic fields are produced by particles that are particles * 1 point a) moving and charged b) moving and neutral c) stationary and charged d) stationary and neutral

Answers

Answer 1

The movement and charge of particles causes them to form magnetic fields.

A magnetic field is created by what particles?

Moving electric charges generate magnetic fields. Everything is constructed of atoms, and each atom has an orbiting nucleus that is composed of protons and neutrons. A weak magnetic field is produced around each atom because the orbiting electrons are tiny moving charges.

What produces a magnetic field and why?

The movement of electric charges is what generates magnetism. Atoms are little building blocks that make up all substances. Each atom contains electrons, which are little particles with electric charges. The electrons around the nucleus, or core, of an atom spin like tops.

the light passing through the grating slits seems to be creating patterns of bright and dark fringes. in terms of light in the real world, what is happening to create the fringes?

Answers

When a light passes through a grating, it split the light to multiple light of different wavelength and which we can see as fringes. It is essentially separate the wavelength of incoming light.

Whilst light goes through a slit, diffraction reasons it to bend and unfold across the display, creating a predictable banded pattern. whilst mild is going thru two slits, new darkish regions seem. The dark and mild areas are produced with the aid of interference of the mild passing via the slits.

White mild can be separated into all seven most important hues of the entire spectrum or rainbow by using a diffraction grating or a prism. The diffraction grating separates mild into colors because the mild passes through the numerous exceptional slits of the grating. this is a transmission grating.

exitance is defined as the power per unit area that is emitted from the surface of an object. for a blackbody radiator, the exitance emitted is dependent upon its temperature. calculate the exitance in w/cm2 for a blackbody radiator at 46 k and 335 k. exitance at 46 k

Answers

The exitance in W/cm² for a blackbody radiator at 335 K is 232 W/cm².

The exitance of a blackbody radiator is given by the Stefan-Boltzmann law: exitance = sigma × [tex]T^4[/tex]

where exitance is the power per unit area emitted from the surface of the object, sigma is the Stefan-Boltzmann constant (5.67 x [tex]10^{-8}[/tex] W/m² K^4), and T is the temperature of the blackbody radiator in Kelvin.

To calculate the exitance in W/cm² for a blackbody radiator at 46 K, we can substitute this temperature into the equation:

exitance = 5.67 x [tex]10^{-8}[/tex] W/m² [tex]K^4[/tex] × [tex](46 K)^4[/tex] = 0.000715 W/m²

Converting this to W/cm², we get:

exitance (W/cm²) = 0.000715 W/m² × (100 cm/m)² = 0.0715 W/cm²

To calculate the exitance in W/cm² for a blackbody radiator at 335 K, we can substitute this temperature into the equation:

exitance = 5.67 x [tex]10^{-8}[/tex] W/m² [tex]K^4[/tex] × [tex](335 K)^4[/tex] = 2.32 W/m²

Converting this to W/cm², we get:

exitance (W/cm²) = 2.32 W/m² × (100 cm/m)² = 232 W/cm²

Can someone help with this

Answers

To solve this problem, you can use the equation for the conservation of energy, which states that the initial potential energy of the spring plus the work done by friction is equal to the final kinetic energy of the block.

The initial potential energy of the spring is given by 0.5kx1^2, where k is the force constant of the spring and x1 is the initial compression of the spring.

The work done by friction is equal to the force of friction times the distance over which it acts, which is given by µkmg*x1, where µk is the coefficient of kinetic friction, m is the mass of the block, g is the acceleration due to gravity, and x1 is the distance the block moves before coming to rest.

The final kinetic energy of the block is given by 0.5mv^2, where m is the mass of the block and v is the final velocity of the block.

You can set up the equation as follows:

0.5kx1^2 + µkmgx1 = 0.5m*v^2

Substituting the given values, we have:

0.5400.3^2 + µk29.810.3 = 0.52*v^2

Solving for µk, we find that:

µk = (0.5400.3^2 - 0.52v^2)/(29.810.3)

The maximum extension x2 of the spring is equal to the distance the block travels, so we can substitute x2 for v:

µk = (0.5400.3^2 - 0.52x2^2)/(29.810.3)

Substituting the value of x2, we find that:

µk = (0.5400.3^2 - 0.520.2^2)/(29.810.3)

Simplifying, we find that:

µk = 0.2

Therefore, the answer is 0.2, letter B.

the right edge of the circuit in the figure extends into a 50 mt uniform magnetic field.

Answers

The magnitude of the circuit is 2.5*10^-2. Since the circuit's right edge in the illustration extends into a 50 mt uniform magnetic field, Rightward is the direction of the magnetic force.

According to the left hand rule, the thumb of the left hand points in the direction of force when the middle finger and index finger point in the direction of current and magnetic field, respectively. The magnetic field and the downward direction are indicated by the way the current in this circuit flows, which is from top to bottom. The thumb points to the right if the index finger points into the page and the middle finger points downward. Thus, the direction of the magnetic force is towards right.

F = (5.0)(10)(50mT)(10^-3/1)(sin90)

F = 2.5*10^-2N

Light rays from the sun make a 300 angle to the vertical when seen from below the surface of a body of water. At what angle above the horizon is the sun? The indices of refraction of glass, water, and air are 1.50, 1.333, and 1.000293, respectively.

Answers

The light rays from the sun is making an angle of 30° then the angle above the horizon of the sun is 48.32°.

What is an angle?

When two lines converge at a point, they produce an angle. The word "angle" refers to the length of the "gap" between these two rays. The symbol is used to denote it.

Radians, a unit of roundness or rotation, and degrees are the 2 most common units used to measure angles. In daily life, angles are present.

As per the information given in the question,

Use the equation of snell's law,

(sin i)/(sin r) = n₂/n₁

r = sin⁻¹ (n₁ sin i)/n₂

Put n₁ = 1.33 and n₂ = 1 also substitute i = 30°

r = sin⁻¹ (1.33) (sin 30)/1

r = sin⁻¹(0.665)

r = 41.68°

The formula for the angle above the horizon,

θ = 90° - r

θ = 90° - 41.68°

θ = 48.32°.
