Answer:Since Mercury's period is 88 days (page 182), the period of this hypothetical planet would be 0.354 ´ 88 = 31 days

Explanation: I hope this is correct

The prices of the different units of volume and mass of mercury are as follows as the Price of one pound of mercury = $2.059

The price of the intermediate volumes of Mercury are determined as follows:Price of 1 g of mercury = $0.00454, Price of 1 cm³ of mercury = $0.0614 and Price of 1 in³ of mercury is $0.996 and Price of 1 g of mercury = $0.00454, Price of 1 cm³ of mercury = $0.0614 and Price of 1 in³ of mercury is $0.996

b. 1 pound = 453.592 g

76 pounds = 76 * 453.592 g = 34473 gPrice of 1 g of mercury = $156.50/34473 Price of 1 g of mercury = $0.00454

Volume of 34473 g of mercury = 34473/13.534

Volume of 34473 g of mercury = 2547.14 cm³

Price of 1 cm³ of mercury = $156.50/2547.14 cm³

Price of 1 cm³ of mercury = $0.0614 Price of 1 in³ of mercury:

1 cm³ = 0.0610 in³

2547.14 cm³ = 2547.14 * 0.0610 in³

2547.14 cm³ = 157.02 in³

Price of 1 in³ of mercury = 156.5/157.02

Price of 1 in³ of mercury = $0.996

In conclusion, the prices of the different units of volume and mass of mercury are found by conversion.

Therefore, Mercury has an orbital period of about 88 Earth days.

The change in density ρ of a substance when the temperature changes by δt can be found using the equation Δρ = -βρδt, where β is the coefficient of thermal expansion, ρ is the initial density, and δt is the change in temperature.

To find the change in density, we simply need to plug in the values for β, ρ, and δt into the equation and solve for Δρ.

Δρ = -βρδt

Assuming that βδt≪1, we can simplify the equation to:

Δρ ≈ -βρδt

Therefore, the change in density ρ of a substance when the temperature changes by δt is approximately equal to -βρδt.

In terms of the variables β, ρ, and δt, the change in density ρ of a substance when the temperature changes by δt is Δρ = -βρδt.

Answer:

0 m/s

Explanation:

Average velocity is displacement over time.

v_avg = Δx / Δt

Displacement is the distance between the start and the finish.

The circumference of the track is:

C = 2πr

C = 2π (7 m)

C ≈ 44 m

The distance covered by the object is:

d = vt

d = (11 m/s) (8 s)

d = 88 m

So the object travels 2 circumferences, meaning it ends back where it started.  Therefore, the displacement is 0 m, and the average velocity is 0 m/s.

Answer: yo  your in high bro  u need to learn this stuff if you want to past u fell me ? Explanation:

in a single slit diffraction experiment, if the slit is narrowed, the distances between adjacent diffraction minima grow farther apart.

A similar pattern is shown on the screen when monochromatic light is fed through a single slit with a finite width in a single slit experiment. The width and intensity of the single-slit diffraction pattern decrease as we go away from the central maximum, in contrast to the double-slit diffraction pattern. A faint lighting can be seen inside the obstacle's geometric shadow when light strikes the sharp edge of the obstruction. This implies that light makes a quick turn. When light travels through an aperture with a size equivalent to the wavelength of the light, the effect becomes noticeable. An alternating dark and bright pattern can be observed if a screen is put in front of a slit that has a width proportional to the wavelength of light. Single slit diffraction is the name given to this phenomena. The double-slit experiment, carried out in 1801, proves that light is a wave. In this experiment, two tiny openings are illuminated by monochromatic light.

The Aharonov-Bohm effect is a fascinating manifestation of the strange and counterintuitive behavior of quantum particles, and has provided important insights into the nature of the universe at the subatomic level.

The Aharonov-Bohm effect is a quantum mechanical phenomenon that describes the behavior of charged particles in the presence of a magnetic field, even when they are not directly interacting with the field itself. This effect arises due to the influence of the vector potential, which is a mathematical quantity that describes the magnetic field.

The effect was first predicted by Yakir Aharonov and David Bohm in 1959, who proposed that the vector potential could affect the phase of the wavefunction of a charged particle, leading to observable interference effects. In other words, even when a particle is shielded from a magnetic field, it can still be influenced by the field through the vector potential, which alters the phase of the particle's wavefunction.

This effect has been demonstrated experimentally using electron interferometry, where electrons are split into two paths and then recombined, producing interference patterns that depend on the strength and geometry of the magnetic field. The Aharonov-Bohm effect has important implications for our understanding of the fundamental principles of quantum mechanics, including the role of gauge symmetry and the relationship between electric and magnetic fields.

Answer:Conduction

Explanation:

Answer:

(a) ω = 1.57 rad/s

(b) ac = 4.92 m/s²

(c) μs = 0.5

Explanation:

(a)

The angular speed of the merry go-round can be found as follows:

ω = 2πf

where,

ω = angular speed = ?

f = frequency = 0.25 rev/s

Therefore,

ω = (2π)(0.25 rev/s)

ω = 1.57 rad/s

(b)

The centripetal acceleration can be found as:

ac = v²/R

but,

v = Rω

Therefore,

ac = (Rω)²/R

ac = Rω²

therefore,

ac = (2 m)(1.57 rad/s)²

ac = 4.92 m/s²

(c)

In order to avoid slipping the centripetal force must not exceed the frictional force between shoes and floor:

Centripetal Force = Frictional Force

m*ac = μs*R = μs*W

m*ac = μs*mg

ac = μs*g

μs = ac/g

μs = (4.92 m/s²)/(9.8 m/s²)

μs = 0.5

The final gravitational force will be 1/16th of the initial gravitational force. In other words, the gravitational force will decrease when the objects are moved from 1 meter apart to 4 meters apart.

The gravitational force between two objects depends on their masses and the distance between them. According to Newton's law of universal gravitation, the force is inversely proportional to the square of the distance between the objects and directly proportional to the product of their masses.

Let's assume that the masses of the objects remain constant. If the objects are initially placed 1 meter apart and then moved to a distance of 4 meters, we can calculate how the gravitational force changes.

The formula for the gravitational force is:

F = G * (m1 * m2) / r^2

Where:

F is the gravitational force between the objects.

G is the gravitational constant.

m1 and m2 are the masses of the objects.

r is the distance between the objects.

Assuming the masses and the gravitational constant remain constant, we can compare the initial and final gravitational forces.

Let's denote the initial force as F_initial and the final force as F_final. Using the formula above, we can calculate the ratio of the final force to the initial force:

F_final / F_initial = (G * (m1 * m2) / (4^2)) / (G * (m1 * m2) / (1^2))

                    = (1 / 16) / (1 / 1)

                    = 1 / 16

This decrease in the gravitational force is a result of the inverse square law. As the distance between the objects increases, the force weakens exponentially. In this case, the force decreases by a factor of 16 because the distance is quadrupled (from 1 meter to 4 meters).
