A solid conducting sphere is given a positive charge Q. How is the charge Q distributed in or on the sphere?
(A) It is concentrated at the center of the sphere.
(B) It is uniformly distributed throughout the sphere.
(C) Its density decreases radially outward from the center.
(D) Its density increases radially outward from the center.
(E) It is uniformly distributed on the surface of the sphere only.
Answers
The charge Q is uniformly distributed throughout the sphere. The correct answer is (B)
When a solid conducting sphere is given a positive charge Q, the charge will distribute itself evenly throughout the surface of the sphere due to the repulsion of like charges. This is known as the "Faraday's ice pail experiment".
According to the principle of electrostatics, the charge on a conductor always resides on its surface and distributes itself in a way that the electric field inside the conductor is zero. Since the charge on a conductor always resides on its surface, it follows that the charge Q in this case must be uniformly distributed throughout the surface of the sphere.
Option (A) is not true because the charge is not concentrated at the center of the sphere. If the charge was concentrated at the center of the sphere, the electric field would not be zero inside the conductor, which contradicts the principle of electrostatics.
Option (C) and (D) are not true because the density of the charge does not change radially outward from the center. If the density decreased or increased radially outward, the electric field inside the conductor would not be zero, which again contradicts the principle of electrostatics.
Option (E) is not true because the charge is distributed throughout the entire volume of the sphere, not just on its surface. A solid conductor has free charges that can move throughout its entire volume, so the charge will distribute itself throughout the entire volume of the sphere until the electric field inside the conductor is zero.
Therefore, the correct answer is (B) it is uniformly distributed throughout the sphere.

A heat engine takes in 500kW of heat power at a temperature of 500oC and rejects 265kW at a temperature of 50oC. (a). Determine the thermal efficiency of this cycle, then (b) Determine the thermal efficiency of the corresponding Carnot cycle and (c) Based on a comparison of these two efficiencies, can this heat engine exist? Explain your answer.
Answers
The thermal efficiency of the given heat engine is 47%, while the thermal efficiency of the corresponding Carnot cycle is 58.24%. The heat engine falls short of the Carnot efficiency, suggesting inefficiencies or design limitations.
(a) To determine the thermal efficiency of the given heat engine, we can use the formula:
Thermal Efficiency = (Net Work Output / Heat Input) * 100
The net work output can be calculated by subtracting the heat rejected from the heat input:
Net Work Output = Heat Input - Heat Rejected
Given:
Heat Input = 500 kW
Heat Rejected = 265 kW
Substituting these values into the formula, we have:
Net Work Output = 500 kW - 265 kW = 235 kW
Now, we can calculate the thermal efficiency:
Thermal Efficiency = (235 kW / 500 kW) * 100 = 47%
Therefore, the thermal efficiency of this cycle is 47%.
(b) The Carnot cycle is an idealized reversible heat engine that operates between two heat reservoirs. Its thermal efficiency can be determined using the formula:
Thermal Efficiency Carnot = 1 - (T_low / T_high)
Given:
T_low = 50°C + 273.15 = 323.15 K
T_high = 500°C + 273.15 = 773.15 K
Substituting these values into the formula, we have:
Thermal Efficiency Carnot = 1 - (323.15 K / 773.15 K) ≈ 0.5824 (58.24%)
Therefore, the thermal efficiency of the corresponding Carnot cycle is approximately 58.24%.
(c) Comparing the thermal efficiency of the given heat engine (47%) with the thermal efficiency of the Carnot cycle (58.24%), we can conclude that the heat engine is less efficient than the corresponding Carnot cycle. In theory, the maximum efficiency any heat engine can achieve is the Carnot efficiency when operating between the same temperature limits. The given heat engine falls short of the Carnot efficiency, indicating that it is not operating at the maximum possible efficiency.
This comparison suggests that the given heat engine may not be feasible or ideal. It could be due to factors such as irreversibilities, inefficiencies in the conversion of heat to work, or losses in the system. Improving the design or addressing these inefficiencies would be necessary to approach the ideal efficiency of the Carnot cycle.

When work is done by a system, does the internal energy of the system increase or decrease?
Answers
Decrease
Explanation:The mathematical relationship between heat, internal energy and work done by the system is given as:
△U = Q + W
where △U is the change in the internal energy
W is the workdone by the system
Q is the heat energy in the system
Since the workdone by the system is negative, when a system does work, there is a depletion in the amount of energy possessed by the system.
Due to this loss of energy by the system as a result of the workdone, the internal energy decreases.
a heavy crate rests on the bed of a flatbed truck. when the truck accelerates, the crate remains where it is on the truck so it too accelerates. what force(s) is/are responsible for the acceleration of the crate? be specific as to the root causes (on, by) of this force.
Answers
The force responsible for the acceleration of the crate is the frictional force between the crate and the bed of the truck.
When the truck accelerates, the crate tends to remain at rest due to inertia. However, the frictional force between the crate and the bed of the truck acts in the forward direction, allowing the crate to accelerate along with the truck.
This frictional force is a result of the interaction between the surfaces of the crate and the truck bed. Without this frictional force, the crate would slide or move independently from the truck's acceleration.
The frictional force arises due to the microscopically rough surfaces of the crate and the truck bed. As the two surfaces are pressed against each other, intermolecular forces come into play, resulting in the generation of the frictional force

Horizontal lightning conductor runs must be connected to the reinforcing steel at intervals not exceeding 20 feet. This helps to create a continuous and low-resistance path for the lightning to follow.
Lightning conductors are installed on buildings to provide a path for lightning to follow and direct it safely to the ground. Horizontal runs of lightning conductors need to be connected to the reinforcing steel of the building to ensure proper grounding. To prevent electrical resistance and ensure that the conductor is effective, the connections should not exceed intervals of 20 feet.
Lightning conductors are designed to provide a safe path for lightning to travel, reducing the risk of damage to the structure. To ensure this safety, the intervals between connections to the reinforcing steel should not exceed 30 meters (100 feet). This is because having a shorter distance between connections allows for a more efficient path for the lightning to follow, thus reducing the chances of damage.

When any object is launched in the air, it moves up to the maximum height where the velocity of the object becomes zero, or we can say the total energy becomes potential. if air friction is neglected, what are the forces acting on the object after it is released
Answers
After an object is launched in the air and it reaches its maximum height, the forces acting on the object are the force of gravity and the normal force.
The force of gravity is pulling the object downward towards the Earth, while the normal force is pushing the object upward to counteract the force of gravity.
These forces are equal and opposite, so they cancel each other out, causing the object to remain at a constant height until another force acts on it. This is known as the principle of equilibrium.
If air friction is neglected, there are no other forces acting on the object. It will continue to move at a constant velocity until another force, such as air resistance or a collision with another object, changes its motion.
In summary, the forces acting on the object after it is released are the force of gravity and the normal force, which are equal and opposite, causing the object to remain at a constant height until another force acts on it.

The reverberation time is 0.05 seconds. As Floor Tile is 0.03. As for Concrete Wall is 0.04.
Required: Solve for the number of Book stack. and Take note that a Book Stack is actually a book shelves.
Hints. To Solve for the number of Book stack you will be needing these sets of formulas to decode the problem.
Formulas: R₁ = 0.049 V/A,, English system
A₁ = (Number of Book Stacks) (Maintenance Factor)
Note: Get the ratio of the A, Stack with books and A, Stack without books .This will serve as a multiplying Factor (MF).
A, Ratio Stack = A, Stack with Book / A, Stack without Book
Note: The Stack or Book Shelves is 5 feet high. Discard the Width of the Book Shelve it is open ended front till back. It only has base to carry the books. It has no partitions or shelves but it has boards that carries the individual level of books.
Answers
Approximately 47,415 book stacks are needed to satisfy the given Reverberation Time (R) in the closed room library.
To solve for the number of book stacks needed to satisfy the given Reverberation Time (R) in the closed room library, we will use the following formulas:
1. A₁ = (Number of Book Stacks) × (Maintenance Factor)
2. A, Ratio Stack = A, Stack with Books / A, Stack without Books
3. R₁ = 0.049 × (Volume of the room) / A
First, let's calculate the volume of the room:
Volume = floor area × height
Volume = π × (60 ft)^2 × 10 ft
Volume ≈ 113,097 ft³
Now, let's calculate the absorption coefficient for the different materials:
A, Stack without Books = 0.17
A, Stack with Books = 0.40
A, Ratio Stack = 0.40 / 0.17
A, Ratio Stack ≈ 2.35
Next, we can calculate the required absorption coefficient (A₁) using the reverberation time formula:
R₁ = 0.049 × Volume / A₁
Given that R₁ = 0.05 seconds, we can rearrange the formula to solve for A₁:
A₁ = 0.049 × Volume / R₁
A₁ ≈ 0.049 × 113,097 ft³ / 0.05 s
A₁ ≈ 111,288 ft²·s
Now, we can calculate the number of book stacks needed (Number of Book Stacks):
Number of Book Stacks = A₁ / (A, Ratio Stack)
Number of Book Stacks ≈ 111,288 ft²·s / 2.35
Number of Book Stacks ≈ 47,415
Therefore, approximately 47,415 book stacks are needed to satisfy the given Reverberation Time (R) in the closed room library.

Edgar kicks the ball to Jerry across the soccer field. The ball stays on the ground. The ball has a mass of 21.79 kg. If the coefficient of friction between the grass and the ball is 1.45, what is the force of friction?
Answers
The force of friction between the ball and the grass is 309.98 N.
What is Friction?
It occurs as a result of the microscopic irregularities on the surfaces that interlock and resist relative motion. The amount of friction between two surfaces depends on factors such as the nature of the surfaces in contact, the force pressing the surfaces together, and the relative speed between the surfaces. Friction can be beneficial in some situations, such as in walking or driving a car, but it can also be a hindrance in others, such as in machines where it causes wear and tear on moving parts.
To calculate the force of friction, we can use the formula:
Friction force = coefficient of friction × normal force
The normal force is the force that the ground exerts on the ball and is equal to the weight of the ball, which is:
Weight = 21.79 kg × 9.81 m/s^2
Weight = 213.68 N
So, the normal force is 213.68 N.
Now we can calculate the friction force:
Friction force = 1.45 × 213.68 N
Friction force = 309.98 N
Therefore, the force of friction between the ball and the grass is 309.98 N.

A 4 kg cart starts up an incline with a speed of 3 m/s and comes to rest 2 m up the incline. The net work done on the cart by all forces is:
Answers
The net work done on the cart by all forces can be determined by calculating the change in kinetic energy of the cart. Given the initial speed, final speed (zero), and the distance traveled, we can calculate the net work done on the cart.
The net work done on an object is equal to the change in its kinetic energy. In this case, the cart starts with an initial kinetic energy and comes to rest at a higher position up the incline, indicating a decrease in kinetic energy.
The initial kinetic energy of the cart is given by K_i = (1/2) * m * v^2, where m is the mass of the cart and v is its initial speed. Since the cart comes to rest, the final kinetic energy, K_f, is zero.
The change in kinetic energy, ΔK, is given by ΔK = K_f - K_i = 0 - [(1/2) * m * v^2].The net work done on the cart is equal to the change in kinetic energy, so the net work done is W = ΔK = -[(1/2) * m * v^2].
