Answer:

A. To find increase in internal energy

We use

CV= f/2* R

=20.77J/molK

So change in internal energy is

nCvdt

So substituting

= 2 x 20.77x 60K

= 2493J

B.

We know that molar specific heat increase by R/2

So CV= (f/2+1)R

Which is 29.1J/milk

So

Increase in internal energy will be

nCvdt

= 2* 29.1*60

= 3490.2J

C. the translational energy is 3/2R

And the total molar specific heat capacity is 7/2R

So the fraction of energy in b due to K.E will be

3/7 * 3490.2

=1495.8J

The induced magnetic field strength 9.5cm radially outward from the center of the plates is  821.052 Tesla.

We know very well that when a charge is moving with some speed in particular direction then, it will induce a magnetic field around its environment. Only moving charge is able to produce magnetic field, stationary charge only produce electric field.

We know that magnetic field is given by=(μ/2πr)×(q/t) where

μ is called as magnetic field constant,

q is the induced charge in the capacitor,

and r is the distance between the two plates

So, we have r=9.5cm=0.095m,(q/t) =39C/sec and μ=4π×10⁻⁷Tesla-m/A.

So, on putting the above values, we get

=>B=(4π×10⁻⁷ × 39)/2π×0.095

=>B=2×39/ 0.095

=>B=78/0.095

=>B=821.052Tesla.

Hence, induced magnetic field is 821.052Tesla.

When the ciliary muscles contract, they increase the curvature of the lens, which leads to a shorter focal length. This allows Joe to focus on objects that are closer to him, such as the squirrel.

Therefore, the correct answer is "increased / decreased."

When Joe shifts his focus from the tree to the squirrel, the ciliary muscles in his eyes contract or relax to adjust the curvature of the lens. The ciliary muscles control the shape of the lens, allowing it to become more or less curved. This change in lens curvature enables the eye to adjust its focal length.

To focus on a nearby object like the squirrel, the ciliary muscles contract, which increases the curvature of the lens. This increased curvature results in a shorter focal length for the cornea-lens system. The shorter focal length allows the incoming light rays from the squirrel to converge and form a focused image on the retina.

On the other hand, when Joe shifts his focus back to the tree in the distance, the ciliary muscles relax. This relaxation reduces the curvature of the lens, resulting in a longer focal length for the cornea-lens system. The longer focal length enables the eye to focus on objects that are farther away, such as the distant tree.

Therefore, the correct answer to the question is "increased / decreased" for Joe's shift in focus from the tree to the squirrel.

\(H_2\) (hydrogen) is not a compound because it's not made of more than one element. Yes we have more than one component, but both components are of the same element H.

Something like \(CO_2\) is a compound because it's made of carbon and oxygen (specifically 1 carbon and 2 oxygen), so we have at least two different elements here.

A charge of 2 C with 100 J kinetic energy undergoes a 30 V voltage difference. The final kinetic energy is 160 J.

The change in kinetic energy of a charge q when it is moved through a potential difference V is given by:

ΔK = qV

In this problem, we are given:

q = 2 C (the charge)

V = 30 V (the potential difference)

Substituting these values into the formula, we get:

ΔK = (2 C) * (30 V) = 60 J

This means that the change in kinetic energy of the charge is 60 joules. Since the electric force is the only unbalanced force, we can assume that the work done on the charge is equal to the change in its kinetic energy. Therefore, the kinetic energy of the charge at the end of this process is:

K_f = K_i + ΔK = 100 J + 60 J = 160 J

Therefore, the kinetic energy of the charge at the end of the process is 160 joules.

While parked, the static friction is what is acting on the car. When the car is started and begins to move the sliding friction acts on it. When the car starts to accelerate the rolling friction would begin to act on it.

When the car is parked on the hill, static friction is acting on the car to keep it from sliding down the hill. Static friction is the force that opposes the motion of an object when it is stationary or at rest.

When the driver starts the car, the car begins to move and sliding friction takes over. Sliding friction is the force that opposes the motion of an object when it is sliding or moving. In this case, sliding friction acts between the tires and the road to slow down the motion of the car.

As the car accelerates, rolling friction starts to act. Rolling friction is the force that opposes the motion of an object when it is rolling. In this case, rolling friction acts between the tires and the road to slow down the rotation of the wheels as they roll on the surface of the road. The rolling friction is typically lower than sliding friction, which makes it easier for the car to maintain a constant speed.

When the driver steps on the brakes, static friction takes over again to slow down the car. The brake pads are pressed against the spinning wheels, and the static friction between the brake pads and the wheels slows down the motion of the car. If the brakes are applied too hard, the wheels may start to slide, and sliding friction will take over again.

In summary, the three types of friction - static, sliding, and rolling - act at different times during the motion of the car. Static friction keeps the car from moving when it is parked on the hill, sliding friction acts when the car is accelerating or decelerating, and rolling friction acts when the car is driving at a constant speed.

Answer:

By the law of conservation of momentum, the total momentum of the system before and after the push must be equal. Therefore, we can use the following equation to solve for Jill's velocity:

(mass of Jack) x (velocity of Jack) = (mass of Jill) x (velocity of Jill)

Plugging in the given values, we get:

(64.3 kg) x (2.19 m/s) = (45.4 kg) x (velocity of Jill)

Solving for the velocity of Jill, we get:

velocity of Jill = (64.3 kg x 2.19 m/s) / 45.4 kg = 3.10 m/s (eastward)

Newton's law of motion consists of three laws for the motion of a body, Where Newton's first law of motion states that An object at rest remains at rest, and an object in motion remains in movement at a steady speed and in a straight line unless acted on by an unequal force. Newton’s first law states that each object will stay at rest or in uniform motion in a straight line unless compelled to alter its state by the action of an outside drive. This tendency to stand up to changes in a state of motion is inertia. On the off chance that all the outside strengths cancel each other out, then there's no net drive acting on the object. In case there's no net constraint acting on the object, at that point the object will keep up a consistent speed.

The observation that all galaxies are moving away from us does not necessarily mean that we are at the center of the universe. Thus the sentence given is False.

This phenomenon can be explained by the concept of cosmic expansion. The universe is constantly expanding, and as a result, the space between galaxies is increasing. This expansion is uniform and affects all galaxies, giving the illusion that they are all moving away from us.

This phenomenon is often described using the analogy of a balloon with dots drawn on its surface. As the balloon inflates, the dots (representing galaxies) move away from each other, even though there isn't a central point on the balloon's surface. Similarly, the universe does not have a definite center, and the observed expansion is due to the stretching of space itself.

Thus, the idea that we are at the center of the universe based on the observation that all galaxies appear to be moving away from us is false. The cosmic expansion, which occurs uniformly, is responsible for this observation and does not imply a central point in the universe.

The value of g will decrease if the mass of the object is decreased.

The acceleration due to gravity, denoted by g, is a constant value that represents the acceleration experienced by an object in free fall near the Earth's surface. It is approximately 9.8 m/s². The value of g is influenced by two factors: the mass of the Earth and the distance between the object and the center of the Earth.

When the mass of the object is decreased, it means there is less gravitational force acting on it. According to Newton's second law of motion (F = ma), the force experienced by an object is directly proportional to its mass. Therefore, if the mass is decreased, the gravitational force acting on the object will also decrease.

Since g represents the acceleration due to gravity, which is determined by the gravitational force, a decrease in the mass of the object will result in a decrease in the value of g. This means that the object will experience a lower acceleration due to gravity.

The government can address the environmental damage caused by thrown-away plastic water bottles through solutions such as implementing a deposit and return system or imposing taxes, which incentivize responsible behavior, reduce plastic waste, and mitigate negative externalities.

a. The economic concept that explains the damage created by thrown-away empty plastic water bottles is "negative externality."

b. Negative externality occurs when the production or consumption of a good or service imposes costs on third parties who are not involved in the transaction. In this case, the irresponsible disposal of plastic water bottles creates environmental damage, such as pollution in landfills and oceans, affecting society as a whole. It is a market failure because the private cost of producing and consuming bottled water does not include the full social cost of the resulting environmental damage.

The market situation in this context involves a divergence between private and social costs. Consumers of bottled water do not bear the full cost of the environmental damage caused by the improper disposal of plastic bottles. Consequently, the market equilibrium for bottled water fails to account for the negative externalities imposed on society.

c. Two solutions available to the government to correct this environmental issue are:

Implementing a plastic bottle deposit and return system: The government can establish a system where consumers pay an additional deposit fee when purchasing plastic water bottles, which is refunded when they return the empty bottles to designated collection points. This incentivizes consumers to return the bottles for recycling or proper disposal, reducing environmental damage.

Imposing taxes or levies on plastic water bottles: The government can impose taxes or levies on the production or consumption of plastic water bottles. This increases the cost of bottled water, reflecting the social cost of environmental damage. The additional revenue generated from these taxes can be used to fund environmental conservation and recycling programs.

d. These solutions will correct the given situation by internalizing the external costs associated with plastic water bottle consumption. By implementing a deposit and return system or imposing taxes, consumers are incentivized to act responsibly by returning the bottles or opting for alternative packaging options. This reduces the amount of plastic waste in landfills and oceans, mitigating environmental damage.

The deposit and return system encourages recycling and reuse of plastic bottles, reducing the need for new bottle production and decreasing overall plastic waste. The taxes or levies increase the price of bottled water, making alternatives like reusable bottles or tap water more economically attractive. The revenue generated from these taxes can be utilized for environmental initiatives such as recycling infrastructure, public awareness campaigns, and research and development of sustainable packaging materials.

Therefore, by internalizing the negative externalities associated with plastic water bottle consumption, these solutions promote responsible behavior, reduce plastic waste, and mitigate the environmental damage caused by improper disposal.

The change in internal energy of the ideal gas, which undergoes an isobaric expansion from 1.00 m³ to 3.00 m³ while 12.5 kJ of heat is transferred to the gas, is 7.5 kJ.

The change in internal energy of an ideal gas can be calculated using the first law of thermodynamics, which states that the change in internal energy (ΔU) is equal to the heat transfer (Q) minus the work done (W) on or by the gas.

The heat transfer (Q) can be determined by the amount of energy transferred to the gas, which is given as 12.5 kJ.

The work done (W) can be calculated using the formula: W = PΔV, where P is the constant pressure and ΔV is the change in volume.

Given that the pressure (P) is constant at 2.50 kPa, and the change in volume (ΔV) is 3.00 m³ - 1.00 m³ = 2.00 m³, the work done can be calculated as follows:

W = PΔV = (2.50 kPa)(2.00 m³) = 5.00 kJ

Now we can calculate the change in internal energy (ΔU):

ΔU = Q - W = 12.5 kJ - 5.00 kJ = 7.5 kJ

Therefore, the change in internal energy of the gas is 7.5 kJ.

The change in internal energy of the ideal gas, which undergoes an isobaric expansion from 1.00 m³ to 3.00 m³ while 12.5 kJ of heat is transferred to the gas, is 7.5 kJ. This change is calculated by subtracting the work done on the gas (5.00 kJ) from the heat transfer (12.5 kJ) according to the first law of thermodynamics.
