Suppose two charges Q1 and Q2 are placed a distance R from a point P. If the magnitude of the net electric feld at P is twice the electric field due to charge 02, this means that the electric field due to charge Q1 is three times greater than the field by charge Q2 and charge Q1 and Q2 are of the same sign. Hint: This means R1=R2 True or False

Among the given options, a neutron star is the smallest object in terms of size and volume. A neutron star is the collapsed core of a massive star after a supernova explosion.

Neutron star is incredibly dense, with a mass similar to that of the Sun packed into a sphere of only about 20 kilometers in diameter. Neutron stars are composed primarily of tightly packed neutrons and have extremely strong gravitational forces.

On the other hand, a red dwarf is a small and relatively cool star, typically less massive than the Sun. While red dwarfs are smaller than neutron stars, they are still much larger in size compared to neutron stars.

A white dwarf is the remnant of a low to medium mass star after it has exhausted its nuclear fuel. They are about the size of the Earth but have a mass comparable to the Sun. While a white dwarf is smaller in size than a red dwarf, it is still larger than a neutron star.

A G-type main-sequence star, like our Sun, is larger in both mass and size compared to a neutron star. These stars are in the prime of their lives and generate energy through nuclear fusion in their cores.

Lastly, the Earth, while smaller than all the other objects mentioned, is still significantly larger than a neutron star.

Answer: 0.28 A

Explanation:

A star grow larger after it exhausts its core hydrogen because B) Hydrogen fusion in a shell outside the core generates enough thermal pressure to push the upper layers outward.

When a star exhausts its core hydrogen, the inward gravitational force is no longer balanced by the outward pressure from fusion, causing the core to contract and heat up. This increased temperature ignites hydrogen fusion in a shell outside the core.

The energy produced by this fusion generates enough thermal pressure to push the upper layers of the star outward, causing it to expand and grow larger.

This expansion continues until the outer layers of the star become cool enough that the pressure is no longer sufficient to resist gravity, and the star begins to contract again. This cycle of expansion and contraction can repeat multiple times, depending on the mass of the star.

The plasma state of matter is made up of electrically charged particles of gaseous matter.

In physics, the term "state of matter" refers to one of the various states in which matter can exist. The solid, liquid, gas, and plasma states of matter can all be observed in daily life.

A gas of ionised atoms that conducts electricity and has almost equal amounts of positively and negatively charged particles is referred to as plasma in physics. That is a common name for the fourth state of matter, which is distinct from the solid, liquid, and gaseous states.

What state of matter consists of electrically charged particles ?

The photon's wavelength emitted during the transition from n = 2 to n = 3 is approximately 256 nm. The photon's wavelength emitted during the transition from n = 1 to n = 3 is about 160 nm. The width of the box is approximately 0.622 nm.

The energy levels of a particle in a one-dimensional box:

Eₙ = (n² ×h²) / (8 × m × L²)

where:

Eₙ: energy level of the particle

n: quantum number of the energy level

h: Planck's constant

m: mass of the particle

L: width of the box.

Transition from n = 2 to n = 3:

Let's assume the wavelength of the photon emitted during this transition is λ.

ΔE = E₃ - E₂

ΔE = ((3² × h²) / (8 ×m × L²)) - ((2² × h²) / (8 × m × L²))

ΔE = (h² / (8× m × L²)) ×(9 - 4)

ΔE = (h²/ (8 × m × L²)) × 5

The energy difference is proportional to the frequency of the emitted photon:

ΔE = h × c / λ

where c is the speed of light.

We can equate the two expressions for ΔE:

(h² / (8 × m × L²)) × 5 = h × c / λ

λ = (8 × m × L² ×c) / (5 × h)

Plugging in the given values:

m = mass of the electron = 9.11 x 10⁻³¹ kg

L = width of the box (to be determined)

c = speed of light = 3 x 10⁸ m/s

λ = (8 ×(9.11 x 10⁻³¹ kg) × L² × (3 x 10⁸ m/s)) / (5 ×(6.626 x 10⁻³⁴ J·s))

Solving for L

L² = (5 × (6.626 x 10⁻³⁴J·s) × λ) / (8 ×(9.11 x 10⁻³¹kg) × (3 x 10⁸ m/s))

L² = 0.00047765 m²

L ≈ 0.021847 m

The wavelength of the photon is given by:

λ = (8 × (9.11 x 10⁻³¹ kg) × (0.021847 m)² × (3 x 10⁸ m/s)) / (5 × (6.626 x 10⁻³⁴J·s))

λ ≈ 256 nm

Transition from n = 1 to n = 3:

Following the same steps,

ΔE = E₃ - E₁

ΔE = ((3² × h²) / (8 ×m ×L²)) - ((1² × h²) / (8 × m × L²))

ΔE = (h² / (m × L²))

Using ΔE = h × c / λ:

(h² / (m × L²)) = h ×c / λ

Simplifying and solving for λ:

λ = (m × L² × c) / h

Plugging in the given values:

λ = ((9.11 x 10⁻³¹ kg) × (0.021847 m)² × (3 x 10⁸ m/s)) / (6.626 x 10⁻³⁴ J·s)

λ ≈ 160 nm

Width of the box (L):

From the above equations,

L² = (5 × (6.626 x 10⁻³⁴J·s) × (426 nm)) / (8 × (9.11 x 10⁻³¹ kg) × (3 x 10⁸ m/s))

L ≈ 0.000622 m or 160 nm

Therefore, the answers are 256 nm, 160 nm, and 0.622 nm respectively.

Calories are a unit of energy measurement that expresses the amount of energy that a food can provide to the body when the food is digested and absorbed.

For example, if we want to know how many calories will you obtain by eating a energy bar that contains 26 g of carbohydrates and 5g of fat, we have that:

Calculating how many calories are in 26 g carbohydrates we have:

Calories (26 g carbohydrates)= 26 * 4 calories

The magnitude of the work done by the car's brakes to slow the car down is 235,537.5 Joules.

The work done:

W = ΔKE

The change observed in kinetic energy (ΔKE) can be find as:

ΔKE = (1/2) × m × (vf² - vi²)

Where m = mass of the car,

vf = final velocity, and

vi = initial velocity.

Let's replace the given values into the equation:

m = 1,500 kg

vf = 28.6 m/s

vi = 45.9 m/s

ΔKE = (1/2) × 1,500 kg  × ((28.6 m/s)² -  (45.9 m/s)²)

Now, determine the magnitude of the work done:

W = ΔKE

ΔKE = (1/2) ×  1,500 kg ×  ((28.6 m/s)² -  (45.9 m/s)²)

= (1/2) ×  1,500 kg ×  (-314.05 m²/s²)

No, the sun cannot explain global warming. Global warming is a phenomenon in which the temperature of the Earth's surface and atmosphere is rising continuously due to human activities such as deforestation, burning of fossil fuels, and industrialization.

This increase in temperature cannot be explained only by an increase in solar radiation.There are several factors which contribute to global warming, including greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the Earth's atmosphere, which causes the planet's temperature to rise. The sun's radiation does contribute to global warming, but it is not the main cause.

i) To calculate the increase in solar radiation that would cause the Earth to warm up by 1 K, we can use the following formula:ΔS = ΔT / αWhere ΔS is the increase in solar constant, ΔT is the increase in temperature, and α is the Earth's albedo (reflectivity).α = 0.30 is the standard value used for the Earth's albedo.ΔS = ΔT / αΔS = 1 K / 0.30ΔS = 3.33 W/m2So, to explain the increase in temperature of 1 K over the last hundred years, the solar constant would need to increase by 3.33 W/m2.

ii) The observed fluctuation of the solar constant over the past 400 years has been around 0.1% to 0.2%. This is much smaller than the 3.33 W/m2 required to explain the increase in temperature of 1 K over the last hundred years. Therefore, it is unlikely that the sun is the main cause of global warming.

The sun cannot explain global warming. While the sun's radiation does contribute to global warming, it is not the main cause. The main cause of global warming is human activities, particularly the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.
