The distance among the two slits is 1.73 x 10⁻³ cm.

The third black fringe will appear 0.627 cm from the center of the dazzling fringe.

(a) The distance between the central bright fringe and the third bright fringe is given by:

Δy = (nλD) / d

where Δy is the distance between the central fringe and the nth bright fringe, λ is the wavelength of the light, D is the distance between the slits and the screen, and d is the distance between the slits.

Substituting the given values, we get:

3.11 cm = (1 x 632.8 nm x 85.0 cm) / d

Solving for d, we get:

d = (1 x 632.8 nm x 85.0 cm) / 3.11 cm = 1.73 x 10⁻³ cm

Therefore, the distance between the two slits is 1.73 x 10⁻³ cm.

(b) The distance between the central bright fringe and the nth dark fringe is given by:

Δy = [(2n - 1)λD] / (2d)

where Δy is the distance between the central fringe and the nth dark fringe, λ is the wavelength of the light, D is the distance between the slits and the screen, and d is the distance between the slits.

Substituting the given values and n=3, we get:

Δy = [(2 x 3 - 1) x 632.8 nm x 85.0 cm] / (2 x 1.73 x 10⁻³ cm) = 0.627 cm

A. the distance between the two slits is approximately 12.8 micrometers. B. the third dark fringe will occur at a distance of approximately 0.557 cm from the central bright fringe.

Slit is a term used to refer to a long, narrow opening or gap. It is most commonly used to describe a thin cut in a piece of material or a surface. Slits are used in a variety of fields, including engineering, manufacturing, and architecture.

A. The distance between the two slits can be calculated using the equation:
d sinθ = mλ
First, we need to calculate the wavelength of the light using the frequency:
\(\lambda = c/f = (3.00 \times 10^8 m/s) / (6.32 \times 10^{14} Hz) = 4.74 \times 10^{-7} m\)
\(tan \theta = (3.11 cm) / (85.0 cm)\)
\(\theta = tan^{-1} (3.11 cm / 85.0 cm) = 2.10^{\circ}\)
Finally, we can substitute the values into the equation and solve for d:
\(d = m\lambda / sin\theta = (3)(4.74 \times 10^{-7} m) / sin(2.10^{\circ}) \approx 1.28 \times 10^-5 m = 12.8 \mu m\)
Therefore, the distance between the two slits is approximately 12.8 micrometers.

B. The distance from the central bright fringe to the third dark fringe can be calculated using the equation:
\(y = (m + 1/2) (\lambda d)\\y = (m + 1/2) (\lambda D/d) = (3 + 1/2) (4.74 \times 10^{-7} m) (85.0 cm) / (12.8 \times 10^{-6} m) \approx 0.557 cm\)
Therefore, the third dark fringe will occur at a distance of approximately 0.557 cm from the central bright fringe.

The pressure will 657 MM Hg.

The relationship between pressure and temperature for a fixed volume of an ideal gas can be described by the Ideal Gas Law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.

P1 = (700 mm Hg) x (101.3 kPa / 1 mm Hg) = 70,910 Pa

T1 = (50 + 273.15) K = 323.15 K

T2 = (30 + 273.15) K = 303.15 K

P2 = (70,910 Pa) x (303.15 K / 323.15 K) = 65,688 Pa

Therefore, the pressure at a temperature of 30°C while keeping the volume constant would be 65,688 Pa, which is equivalent to 657 mm Hg.

Since the volume is constant in this case, we can see that the pressure is directly proportional to the temperature. Therefore, if we decrease the temperature by 20°C, the pressure will also decrease by a factor of (T2/T1)(1-γ), where γ is the adiabatic index of the gas. In reality, the pressure will not decrease exactly as calculated using the Ideal Gas Law, since the gas is not an ideal gas and the volume may not remain constant. However, the Ideal Gas Law provides a useful approximation in many situations.

The ball was dropped from a height of approximately 11.47 meters. To determine the height from which the ball was dropped, we can use the principle of conservation of energy.

The initial potential energy (PE) of the ball is converted into kinetic energy (KE) when it hits the ground.

The potential energy (PE) of an object at a height (h) is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height.

The kinetic energy (KE) of an object is given by the formula KE = (1/2)mv², where m is the mass and v is the velocity.

Since the ball hits the ground with a velocity of 15 m/s, we can equate the initial potential energy to the final kinetic energy:

mgh = (1/2)mv²

Cancelling the mass (m) from both sides of the equation:

gh = (1/2)v²

Substituting the given values:

9.8h = (1/2)(15)²

Simplifying:

9.8h = 112.5

Dividing both sides by 9.8:

The momentum of the system is -20 kg*m/s in the negative x-axis direction.

What is momentum?

Momentum is a fundamental concept in physics that describes the motion of an object. It is a vector quantity, meaning it has both magnitude and direction. The momentum of an object is equal to its mass multiplied by its velocity, or p = mv. The direction of the momentum is the same as the direction of the velocity.

The momentum of a system can be determined by summing the momenta of the individual objects in the system. The momentum of an object is equal to its mass multiplied by its velocity. The direction of the momentum is the same as the direction of the velocity.

For the first object, the momentum is:

p1 = mi * vi

p1 = 6 kg * 13 m/s

p1 = 78 kg*m/s (in positive x-axis direction)

For the second object, the momentum is:

p2 = mz * vz

p2 = 14 kg * -7 m/s

p2 = -98 kg*m/s (in negative x-axis direction)

To find the total momentum of the system, we add the momenta of the two objects:

p_total = p1 + p2

p_total = 78 kgm/s + (-98 kgm/s)

p_total = -20 kg*m/s (in negative x-axis direction)

So the momentum of the system is -20 kg*m/s in the negative x-axis direction.

One aspect of mirror-image perception is that one side tends to appear reversed or flipped. This phenomenon is known as laterality reversal or mirror reversal.

When we observe ourselves or objects in a mirror, our perception of the image is often influenced by the fact that it appears reversed compared to the actual object. For example, if we raise our right hand, the mirror image appears to show the hand being raised on the left side. This can lead to a momentary confusion or adjustment in our perception.

The tendency for mirror images to appear reversed is due to the way our brains process visual information. Our visual system is wired to interpret images based on the relationship between our body and the external world. When we encounter a mirror image, the visual cues that we are accustomed to are reversed, leading to the perception of a flipped image.

This mirror reversal effect has been studied in various contexts, including neuroscience, psychology, and cognitive science. It highlights the intricate nature of visual perception and the role of our brains in interpreting the world around us.

The relativistic momentum of the electron if the kinetic energy of an electron is 45% of its total energy is 2 times the square root of the rest mass of the electron times 45% of its total energy.

To determine the kinetic energy of an electron is 45% of its total energy, we can use the relativistic formula for total energy to find the rest energy of the electron. The formula is:

E = (m0c²) / √(1 - v²/c²)

where E is the total energy, m0 is the rest mass of the electron, c is the speed of light, and v is the velocity of the electron.

Since we are given that the kinetic energy is 45% of the total energy, we can write:

K = 0.45 × E

where K is the kinetic energy.

Using the formula for kinetic energy, we can write:

K = (p² / 2m0)

where p is the relativistic momentum of the electron.

Solving for p, we get:

p = √(2m0K)

Substituting K = 0.45E, we get:

p = √(0.9m0E)

To find E, we can use the fact that the kinetic energy plus the rest energy is equal to the total energy:

E = K / 0.45

Substituting this into the expression for p, we get:

p = √(0.9m0K / 0.45)

p = √(2m0K)

So the relativistic momentum of the electron is equal to the square root of twice the rest mass of the electron times its kinetic energy, which is 2 times the square root of the rest mass of the electron times 45% of its total energy.

√12 is  degrees Celsius per meter.

What is tempreture?

tempreture is the degree of hotness or coldness of any kind of objects.

Sol-

The highest rate of tempreture increase is given as 6degrees as per the question

Imagine this high rate as a diagonal vector pointing in the northeast direction.

This vector has an x component (horizontal, or east) and a y component (vertical, or north).

The highest rate (maximum) is found as the magnitude of these two components.

It is the square root of (x^2)+(y^2).

6= √((x^2)+(y^2))

-> Take the square of both sides to remove the square root on the right side of the equation.

36 = (x^2)+(y^2)

-->The x^2 and y^2 values each must equal 8 in order to get:  12

(x^2) = 12

x = √12

(y^2) = 12

y = √12

If the object moves directly north, it is therefore moving only in the y-direction.

Thus, it is increasing tempreture at a rate of √12 degrees Celsius per meter.

To simultaneously measure the current in a resistor and the voltage across it, you would need to use an ammeter and a voltmeter in the same circuit. The ammeter is used to measure the current flowing through the resistor and must be placed in series with the resistor, meaning that it is connected in-line with the current flow. On the other hand, the voltmeter is used to measure the voltage across the resistor and must be placed in parallel with the resistor, meaning that it is connected across the two ends of the resistor.

Option a (ammeter in series and voltmeter in series) would not allow for the voltmeter to measure the voltage across the resistor as it would only measure the voltage drop across the ammeter. Option b (ammeter in series and voltmeter in parallel) is the correct answer as it allows for both the current through and voltage across the resistor to be measured simultaneously. Option c (ammeter in parallel and voltmeter in series) would not allow for the ammeter to measure the current through the resistor as it would be connected in parallel with it. Option d (ammeter in parallel and voltmeter in parallel) would not allow for the voltmeter to measure the voltage across the resistor as it would be connected in parallel with it.
