(a) The magnitude of the electric dipole moment is  0.0270 pC m

(b) The difference between the potential energies for the two orientations is 7.38 mJ and U_antiparallel is -3.69 mJ.

(a) The magnitude of the electric dipole moment can be calculated using the formula:

p = q * d

where q is the magnitude of each charge and d is the separation between the charges. Plugging in the values, we get:

p = 3.60 nC * 7.50 * 10^-6 m = 0.0270 pC m

(b) The difference between the potential energies for the two orientations can be calculated using the formula:

ΔU = p * E

where p is the electric dipole moment and E is the electric field strength. The potential energy is proportional to the dot product of the electric dipole moment and the electric field. So when the dipole moment is parallel to the electric field, the potential energy is at a maximum, and when it's antiparallel, the potential energy is at a minimum.

For the orientation parallel to the electric field:

U_parallel = p * E = 0.0270 pC m * 1370 N/C = 3.69 mJ

For the orientation antiparallel to the electric field:

U_antiparallel = -p * E = -0.0270 pC m * 1370 N/C = -3.69 mJ

The difference between the two potential energies is:

ΔU = U_parallel - U_antiparallel = 3.69 mJ - (-3.69 mJ) = 7.38 mJ

So the difference in potential energy between the two orientations is 7.38 mJ.

The time taken for a comet to complete each orbit around the Sun depends on the eccentricity of its orbit. Kepler's laws of planetary motion provide insights into this relationship. If the eccentricity is large, each orbit may take about 2 years.

Kepler's laws of planetary motion describe the motion of objects in orbit around the Sun, including comets. In this case, the comet orbits the Sun on a highly eccentric orbit with an average distance (semimajor axis) of 1 astronomical unit (AU).

Kepler's first law (law of orbits) states that the orbit of a planet (or comet) is an ellipse with the Sun at one of the foci. This law does not directly provide information about the time taken to complete each orbit.

Kepler's second law (law of areas) states that a line connecting the Sun to a planet (or comet) sweeps out equal areas in equal time intervals. This law implies that a planet or comet moves faster when closer to the Sun (perihelion) and slower when farther away (aphelion). However, it does not directly provide information about the time taken to complete each orbit.

Since the average distance (semimajor axis) of the comet's orbit is 1 AU, we can use Kepler's third law to determine the time taken to complete each orbit. Assuming the eccentricity of the orbit is large, the period of the comet's orbit is approximately 2 years (1 year * 2).

In conclusion, the time taken for a comet to complete each orbit depends on the eccentricity of its orbit, as described by Kepler's third law. If the eccentricity is large, each orbit may take about 2 years.

The two critical factors that lead to a greater distance of travel of the moving debris during a rockfall are the height of the fall and the initial velocity of the rocks or debris.

A rockfall is a natural disaster that occurs when rocks or debris become dislodged from a steep slope or cliff and move downhill under the influence of gravity. The distance traveled by the moving debris during a rockfall depends on several factors, including the angle of the slope, the size and shape of the rocks or debris, and the surface characteristics of the slope.

However, two critical factors that lead to a greater distance of travel of the moving debris during a rockfall are the height of the fall and the initial velocity of the rocks or debris.

Firstly, the height of the fall plays a crucial role in determining the distance traveled by the moving debris. The higher the height of the fall, the more potential energy the rocks or debris possess. As the debris falls, this potential energy is converted into kinetic energy, increasing the velocity of the moving debris. Therefore, rocks or debris that fall from a greater height will have a higher initial velocity and travel further down the slope before coming to a stop.

Secondly, the initial velocity of the rocks or debris is another factor that determines the distance traveled during a rockfall. The initial velocity of the debris depends on the angle of the slope, the size and shape of the rocks or debris, and the surface characteristics of the slope. If the slope angle is steep, the initial velocity of the debris will be higher, leading to a greater distance traveled by the moving debris.

In conclusion, the two critical factors that lead to a greater distance of travel of the moving debris during a rockfall are the height of the fall and the initial velocity of the rocks or debris.

The critical angle of the transparent material is 35.3 degrees.

The critical angle is the angle of incidence at which the angle of refraction is 90 degrees. In this case, the angle of refraction is 32 degrees. Therefore, the critical angle is calculated as follows:

sin(critical angle) = sin(90 degrees) / sin(angle of refraction)

sin(critical angle) = 1 / sin(32 degrees)

sin(critical angle) = 0.574

critical angle = arcsin(0.574)

critical angle = 35.3 degrees

Product inhibition is an important factor to consider when designing and optimizing chemical and biochemical reactions, and strategies to mitigate its effects may be necessary to improve the efficiency of these processes.

This is known as product inhibition or feedback inhibition. Product inhibition occurs when the product of a chemical reaction accumulates to a level that slows down or stops the reaction from proceeding further. This phenomenon is often seen in enzyme-catalyzed reactions, where the product of the reaction binds to the enzyme and inhibits its activity. The inhibition may be reversible or irreversible, depending on the nature of the enzyme and the product. In some cases, product inhibition can be overcome by removing the product from the reaction mixture, or by diluting the reaction mixture with fresh substrate.

Answer:

The energy of the emitted photoelectrons can be determined using the concept of the photoelectric effect. According to the photoelectric effect, the energy of the emitted photoelectrons is equal to the difference between the energy of the incident photons and the work function of the material.

In this case, we are given that the incident photons have an energy of 10 electron volts (eV). Let's assume the work function of the material is represented by W (in eV).

The energy of the emitted photoelectrons (Ee) can be calculated as:

Ee = incident photon energy - work function

Ee = 10 eV - W

We are also given that when photons with an energy of 5 eV strike the same surface, the emitted photoelectrons have an energy of 2 eV. Using this information, we can set up another equation:

2 eV = 5 eV - W

Solving this equation for W, the work function:

W = 5 eV - 2 eV

W = 3 eV

Now, we can substitute the value of the work function into the equation for the energy of the emitted photoelectrons:

Ee = 10 eV - W

Ee = 10 eV - 3 eV

Ee = 7 eV

Therefore, when photons with 10 electron volts of energy strike the photoemissive surface, the energy of the emitted photoelectrons will be 7 electron volts.

To solve the first part of the problem, we can use the conservation of energy principle. At the beginning, the roller coaster has potential energy, which is converted to kinetic energy as it moves down the track. At the top of the second hill, the roller coaster has a certain amount of potential energy and kinetic energy.

Let's first calculate the speed of the roller coaster at the bottom of the first hill using conservation of energy:

mgh = (1/2)mv^2

where m is the mass of the roller coaster, g is the acceleration due to gravity, h is the initial height, and v is the speed at the bottom of the first hill.

Plugging in the values, we get:

890 kg * 9.81 m/s^2 * 97 m = (1/2) * 890 kg * v^2

Solving for v, we get:

v = 43.26 m/s

Now, let's find the speed of the roller coaster at the top of the second hill using conservation of energy again:

(1/2)mv1^2 + mgh1 = (1/2)mv2^2 + mgh2

where v1 is the velocity at the bottom of the first hill, h1 is the height at the bottom of the first hill, h2 is the height at the top of the second hill, and v2 is the velocity at the top of the second hill.

Plugging in the values, we get:

(1/2) * 890 kg * (43.26 m/s)^2 + 890 kg * 9.81 m/s^2 * 62 m = (1/2) * 890 kg * v2^2 + 890 kg * 9.81 m/s^2 * 62 m

Solving for v2, we get:

v2 = 30.3 m/s

Therefore, the velocity of the roller coaster at the top of the second hill is 30.3 m/s.

For the second part of the problem, we can use the work-energy principle. The work done by the frictional force is equal to the change in kinetic energy of the roller coaster.

Let F be the average force required to bring the roller coaster to a stop at a distance of 130 m. The work done by this force is:

W = Fd = (1/2)mvf^2

where d is the distance over which the roller coaster comes to a stop, and vf is the final velocity, which is zero.

Plugging in the values, we get:

F * 130 m = (1/2) * 890 kg * (0 m/s)^2

Solving for F, we get:

F = 0 N

Therefore, this means that no force is required to bring the roller coaster to a stop at 130 m, since there is no friction. If there were friction, the average force required would depend on the coefficient of friction and the initial velocity of the roller coaster.
