Answer:

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released. :D

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.

Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.

Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.

a) The particle moves through the parallel plates undeflected because the electric force is balanced by the magnetic force.

b) The sign of the charge on the particle can be determined by the direction of the magnetic field and the direction of the particle's motion.

a) The particle moves through the parallel plates undeflected because the electric force and the magnetic force on the particle are equal in magnitude and opposite in direction. The electric force is given by F_e = qE, where q is the charge on the particle and E is the electric field between the plates. The magnetic force is given by F_B = qvB, where v is the velocity of the particle and B is the magnitude of the magnetic field. In this case, the electric field between the plates is perpendicular to the magnetic field, so the forces are perpendicular and the particle moves undeflected.

b) The sign of the charge on the particle can be determined by the direction of the magnetic field and the direction of the particle's motion. Since the particle moves in a clockwise direction in the region to the right of the plates, the magnetic force on the particle must be directed towards the center of the circle. This means that the direction of the magnetic field is out of the page, which can only be the case if the charge on the particle is negative. If the charge were positive, the magnetic force would be directed out of the page, and the magnetic field would have to be directed into the page to balance the electric force, which is not the case. Therefore, the particle has a negative charge.

Answer:

Omnidirectional antennas are inadvisable to be used because when oriented vertically they radiate radio power equally in all horizontal directions, but heir radio power varies with the angle to the axis, reducing to zero at the axis.

Explanation:

Omnidirectional antennas radiates equal radio power in all directions perpendicular to an axis, with power varying with the elevation angle. This means that their power declines to zero on the axis. This is unlike the isotropic antennas that radiates equal power in all directions, without any reduction in radio power with angle to the axis. Omnidirectional antennas are mostly used for radio broadcasting antennas in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks etc.

Yes, The bubbles in electrocuted water is considered as a new substance.

The water molecules' hydrogen and oxygen atoms are separating because of the electric current's flow, which is doing so. Bubbles of oxygen and hydrogen are consequently produced as a result.

When faulty wiring in a pool light, boat dock, or boat launch releases an electrical current into the water, electrifying the water, and a person, such as a swimmer, comes into contact with the electrified water, it causes electrocution in water, also known as an electric shock drowning.

Answer:

\(v_2=8.85\times 10^{-4}\ m/s\)

Explanation:

We have,

Mass of a wrench, m₁ = 4 g = 0.004 kg

Speed of wrench, v₁ = -15 m/s

Mass of the Astronaut, m₂ = 70 kg

It is required to find Astronaut's velocity. Let it is v₂. Using the conservation of linear momentum to find it.

\(m_1v_1=m_2v_2\\\\v_2=\dfrac{m_1v_1}{m_2}\\\\=\dfrac{0.004\times (-15)}{70}\\\\=-8.85\times 10^{-4}\ m/s\)

So, his velocity is \(8.85\times 10^{-4}\ m/s\).

So acceleration of the bike which started from rest, reaches at speed of 7.10 m/s by travelling distance 35.4 m will be 0.712 m/ sec^2.

A thermometer sensitive is a bulb with a thin glass wall. so, option (a) is correct.

What is thermometer?

A thermometer is a device that measures temperature. The three most used ways to measure temperature are in degrees Celsius, degrees Fahrenheit, and degrees kelvin. The metric system incorporates the Celsius scale.

What is thermometer sensitive?

The degree of change in a thermometer's thermometric property for a unit change in temperature is referred to as its sensitivity. It speaks of the smallest temperature difference that may be seen or quantified. The difference between the maximum and least temperature is referred to as a thermometer's range.

Because of shorter wavelength, Blue light would release electrons with more kinetic energy. Yellow light would generate more electrons.

Blue and yellow light must have different intensities for the yellow light to emit electrons with more kinetic energy.

The yellow light must be more intense than the blue light since both lasers send the same amount of energy to the metal surface. The yellow light must therefore produce more electrons.

The expelled electrons must have a higher kinetic energy since the wavelength of blue light is shorter.

It is demonstrated by the photoelectric effect that light can behave like a particle. When photons are shone on a metal surface, electrons are expelled from the surface of the metal, which causes the photoelectric effect.

When compared to green light, the higher energy blue light ejects electrons with more kinetic energy.

No electrons are released by light below a specific frequency. In contrast, light exceeding that threshold frequency can emit electrons even at modest intensities. Electron ejection speed appears to be frequency dependent, with an increase in frequency resulting in an increase in speed.

The Brewster's angle for light traveling in vacuum and reflecting off a piece of glass having a refractive index of 1.52 is 56.7 degrees.

Brewster's angle is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.

When unpolarized light is incident at this angle, the light that is reflecting from the surface is therefore perfectly polarized.

The special angle of incidence that produces a 90 degrees angle between the reflected and refracted ray is called the Brewster angle, ∅p.

Formula for Brewster's angle: tan(∅) = μ

Given, The refractive index is μ. =1.52

By given the above relation,

tan∅ = μ

∅ = \(tan^{-1}\)(μ)

∅ = \(tan^{-1}\)(1.52)
