The energy stored in the combination of capacitors when they are connected in series is 0.0719 joules or 71.9 mJ.

To calculate the energy stored in the combination of capacitors when they are connected in series, we need to first calculate the equivalent capacitance of the combination using the formula:

1/Ceq = 1/C₁ + 1/C₂

Substituting the given values, we get:

1/Ceq = 1/1.50 uF + 1/4.00 uF

Ceq = 1.071 uF

Next, we need to calculate the voltage across each capacitor using the formula:

Q = Ceq × V

where Q is the charge on the combination of capacitors, and V is the voltage across the combination.

Substituting the given values, we get:

V = Q / Ceq = (4.0 x 10⁻⁴ C) / (1.071 uF) = 373.3 V

Now, we can calculate the energy stored in the combination using the formula:

U = 0.5 × Ceq * V²

Substituting the calculated values, we get:

U = 0.5 × (1.071 uF) × (373.3 V)² = 71.9 mJ

The 1.2g bullet with kinetic energy of 1.2J would travel a distance of 80 meters in 2 seconds, under the assumptions and simplifications we made.

To determine the distance traveled by a 1.2g bullet with kinetic energy of 1.2J in 2 seconds, we need to use the equations of motion. However, we do not have enough information to directly use these equations. We need to make some assumptions and simplifications to solve this problem.

Let's assume that the bullet is fired horizontally, without any air resistance or any other forces acting on it besides gravity. In this case, the motion of the bullet is a projectile motion, and we can use the following equation to determine its horizontal distance traveled:

d = v_x * t

where d is the horizontal distance traveled, v_x is the horizontal velocity of the bullet, and t is the time elapsed.

To find v_x, we need to use the kinetic energy of the bullet:

KE = 0.5 * m * v^2

where KE is the kinetic energy, m is the mass of the bullet, and v is the velocity of the bullet. Rearranging this equation to solve for v, we get:

v = sqrt(2 * KE / m)

Substituting the given values, we get:

v = sqrt(2 * 1.2 J / 0.0012 kg) = 40 m/s

Now we can use the equation for d to find the distance traveled by the bullet:

d = v_x * t = v * cos(theta) * t

where theta is the angle between the initial velocity and the horizontal direction. Since the bullet is fired horizontally, theta = 0, and cos(theta) = 1. Thus, we have:

d = v * t = 40 m/s * 2 s = 80 meters

(a) There is only one degree of freedom in this problem since the collar can move along the shaft but cannot rotate. The constraints are that the distance between the collar and the pivot point is always equal to l, and the collar cannot move perpendicular to the shaft.

(b) The forces acting on the collar are the spring force and the gravitational force. Since the collar is sliding along a frictionless shaft, there is no frictional force. The equation of motion for the collar is given by:

m(d²x/dt²) = -k(x-l) - mg

where x is the displacement of the collar from its equilibrium position.

(c) The normal force between the collar and the shaft is perpendicular to the shaft and balances the component of the gravitational force that is perpendicular to the shaft. As the collar moves away from its equilibrium position, the spring force becomes unbalanced and the normal force changes accordingly. The normal force is given by:

N = mgcos(θ) + k(x-l)sin(θ)

where theta is the angle between the shaft and the vertical axis.

For energy to be transferred as heat between two bodies in physical contact, the bodies must be at different temperatures.

When two bodies are in physical contact, energy is transferred from the body at a higher temperature to the body at a lower temperature. This transfer of energy occurs through the mechanism of heat, which is the flow of thermal energy due to a temperature difference.

The rate of heat transfer depends on the temperature difference between the two bodies and the thermal conductivity of the materials they are made of. Heat always flows from hotter to colder regions until thermal equilibrium is reached, where both bodies reach the same temperature and there is no further net transfer of heat energy.

The FDA recommends cooking a turkey to an internal temperature of 165°F (73.9°C) to eliminate harmful bacteria like salmonella and campylobacter. This temperature must be maintained for a minimum of 15 seconds in the thickest part of the turkey, which is usually the breast or the innermost part of the thigh.

However, there are a few other things to keep in mind when cooking a turkey. First, make sure to properly thaw the turkey before cooking it. This can be done in the refrigerator, cold water, or a microwave. Second, make sure to cook the stuffing separately rather than inside the turkey to ensure that it reaches a safe temperature. Third, use a meat thermometer to check the temperature of the turkey in multiple places to make sure it is fully cooked. Finally, allow the turkey to rest for at least 15-20 minutes before carving to allow the juices to redistribute throughout the meat. All these steps can help ensure that your Thanksgiving dinner is both delicious and safe to eat.

The correct answer is(b). There is a physical change from the solid state to a gas state where energy between the molecules increases.

During sublimation, carbon dioxide transitions directly from the solid state (dry ice) to the gas state without passing through the liquid phase. In this process, individual molecules of carbon dioxide gain energy from the surroundings, leading to an increase in their kinetic energy and molecular movement.

As a result, the carbon dioxide molecules separate from each other and form a gas. This phase change is considered a physical change rather than a chemical change since the chemical composition of carbon dioxide remains the same throughout the process.

Therefore, the sublimation of carbon dioxide results in a physical change where the molecules transition from the solid state to the gas state, gaining energy and increasing their molecular movement.

The deceleration of the car is approximately -5 m/s^2.

To calculate the deceleration of the car, we need to first convert the speed from kilometers per hour (km/h) to meters per second (m/s) since the standard unit of acceleration is meters per second squared (m/s^2).

Given:

Speed = 54 km/h

Time taken to stop = 3 s

To convert the speed from km/h to m/s, we can use the conversion factor: 1 km/h = 1000 m/3600 s.

Speed in m/s = (54 km/h) * (1000 m/3600 s)

= 15 m/s

Now, we can calculate the deceleration using the equation of motion:

Deceleration = (Final velocity - Initial velocity) / Time

Since the car comes to a stop, the final velocity is 0 m/s and the initial velocity is 15 m/s.

Deceleration = (0 m/s - 15 m/s) / 3 s

= -15 m/s / 3 s

= -5 m/s^2

The negative sign indicates that the deceleration is in the opposite direction of the initial velocity, which means the car is slowing down.

The frequency of the light in the air is the same as in the glass, which is determined by the wavelength and not affected by the refractive index.

The frequency of light remains constant as it passes from one medium to another. Therefore, the frequency of the light in the air (n=1.00) is the same as the frequency of the light in the glass (n=1.50).

However, the wavelength of the light changes as it passes from one medium to another. The relationship between the wavelength of the light in air (λ_air) and the wavelength of the light in the glass (λ_glass) is given by:

n_air * λ_air = n_glass * λ_glass

where n_air and n_glass are the refractive indices of air and glass, respectively.

Substituting the values given:

1.00 * λ_air = 1.50 * 695 nm

λ_air = (1.50 * 695 nm) / 1.00

λ_air = 1042.5 nm

Therefore, the wavelength of the light in air is 1042.5 nm, and the frequency remains the same as it was in the glass.

The presence of dark energy has been deduced by studying the movement of stars and galaxies.

Around the 1990's, astronomers studying the rate of expansion of the universe discovered something abnormal. Instead of slowing down due to gravity or even remaining the same, the universe was expanding at an alarming rate.

The rate of expansion was measured using the light coming from supernovae ( massive exploding stars ). While puzzled by this idea, some scientists brought up an old idea by Albert Einstein, also called his "biggest blunder", that there is an energy contained in the vacuum of space that is repulsive and is accelerating the expansion of the universe. This mysterious energy is what is known as dark energy today.

Dark energy, most at times is confused with dark matter. Very little is known about it as of today, as it is invisible because it doesn't react to visible light. The presence of dark energy is therefore studied by monitoring its gravitational pull on distant stars and galaxies.
