A ball which is most likely to topple the bowling pin is: 2. the rubber ball.

The law of conservation of momentum states that the total linear momentum of an isolated (closed) system would always remain constant (the same) with respect to time, unless an external force is applied.

Additionally, the law of conservation of momentum states that the total momentum of two interacting objects in an isolated (closed) system would be the same or remain constant, provided no external force is applied.

In this scenario, we can logically deduce that momentum is conserved in the interaction between the large wooden bowling pin and a ball, but more momentum would be transferred from the rubber ball to the bowling pin, rather than from the putty ball to the rubber ball.

In conclusion, the rubber ball is more likely to topple the bowling pin over because it acts as an external force.

Edison means with the claim that "there is no similar institution in existence" was that he had created the first ever laboratory dedicated to research and invention.

After the successful installation of his first power plants in the starting of 1880s, Edison lived up to his reputation as the "Inventor of the Age." For many years Edison had no single, central laboratory. He researched at his electrical manufacturing shops in Harrison, New Jersey and New York.

When his wife Mary died in 1884 he withdrew somewhat from electric light work. In 1887 he had decided to build a new facility near his house in West Orange, New Jersey, several times bigger than the Menlo Park laboratory had been. The new laboratory equipped with everything Edison had learned about the process of invention.

WACC (Weighted Average Cost of Capital) is a calculation used to assess a company's cost of capital. It is computed by multiplying each source of capital (equity, debt, and preferred stock) by its relevant weight and then summing these up.

In this question, Ace Batteries is utilizing the CAPM (Capital Asset Pricing Model) to determine the cost of equity capital.Ace Batteries' WACC can be reduced if the company's beta decreases. The beta of a company is a measure of its market risk or volatility, and it is a component of the CAPM formula

As a result, a lower beta lowers the cost of equity capital, lowering the company's WACC. Consequently, option c: A decrease in the company's beta, will REDUCE Ace Batteries' WACC (weighted average cost of capital).

The false statement is "The work done by external net force can be represented by the area under force/displacement." Therefore, option d) is correct.

In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.

Option a) is true as Joules (J) is the unit of work.

Option c) is also true as we need to zero the force sensor on the cart before hooking on any string to obtain accurate readings.

However, option d) is false as the work done is a product of force and displacement, and not force and distance.

The correct statement is b) The work done by external net force can be represented by the area under the speed/displacement curve.

The kinetic energy of a 1.6 g particle with a speed of 0.80 c is approximately 2.03 x 10^14 Joules.

To calculate the kinetic energy of the particle, we first need to convert its mass to kilograms (kg) and then use the relativistic kinetic energy formula.
Step 1: Convert mass to kg
1.6 g = 0.0016 kg
Step 2: Use the relativistic kinetic energy formula
KE = (γ - 1)mc^2, where γ (gamma) is the Lorentz factor, m is the mass, and c is the speed of light.
Step 3: Calculate the Lorentz factor
γ = 1 / √(1 - v^2/c^2), where v is the particle's speed (0.80c).
γ = 1 / √(1 - (0.80c)^2/c^2) = 1 / √(1 - 0.64) = 1 / √(0.36) = 1 / 0.6 = 5/3
Step 4: Calculate the kinetic energy
KE = ((5/3) - 1)(0.0016 kg)(3 x 10^8 m/s)^2
KE ≈ 2.03 x 10^14 Joules

Explanation:

To solve this we must be knowing each and every concept related to displacement and its calculations. Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.

The distance along a straight line connecting an object's original and final positions is its displacement [x].

Displacements are not always a good thing. It may also be 0 or negative. A negative displacement indicates that the item has moved away from the origin and toward the right if a positive direction is situated to the right of both the origin.

If the body's velocity at a given moment in time is 'v' m/s, then displacement may be expressed mathematically as-

v = dx /dt

dx = vdt

Integrating on both sides, we get

∫dx = ∫vdt

∫dx  [x = 0 to x = x] = ∫vdt  [ t = 0 to t = 16 s]

x = v [16 - 0]

x = 16v

The average power required by a 1000 kg speedboat to go from rest to 20.0 m/s in 5.00 s is 60000 Watts.

The average power required to accelerate an object is equal to the force required to overcome resistance multiplied by the velocity gained. In this case, the drag force fd opposes the acceleration of the speedboat, and so the net force on the boat is equal to the difference between the force applied to the boat and the drag force:

Fnet = Fapplied - fd = ma - fd

where m is the mass of the boat (1000 kg) and a is the acceleration. The acceleration can be calculated from the velocity gained and the time taken:

a = (vf - vi) / t = (20 m/s - 0 m/s) / 5.00 s = 4 m/s^2

So, the net force is:

Fnet = ma - fd = 1000 kg * 4 m/s^2 - 500 N = 3000 N

The power required to overcome the drag force and accelerate the speedboat is equal to the net force multiplied by the velocity gained:

P = Fnet * v = 3000 N * 20 m/s = 60000 Watts

Therefore, the average power required is 60000 Watts.

Insulator: A material with a substantial gap between the valence and conduction bands. Because no electrons can travel up to the conduction band, the valence band is filled. As a result, the conduction band is completely vacant.

Conductor: The valence bands of a conductor are not complete, hence the conduction band is continuous with the valence band. Electrons in the valence band will migrate to the conduction band, leaving a positive charged vacancy known as a hole behind.

Insulator Defintion:

Energy band Theory:

According to this theory the overlapping of valence band and conduction band tells us about the conductivity of a substance, in insulators the valence band and the conduction band both are separated to a large distance which will cannot be over lapped by applying small energy. If conduction band and valence band don't overlap there would be no exchange of electrons and in that case the material cannot conduct electricity or heat.

Presence of Free Electrons:

The conductivity of a element is wholly and solely dependent upon the presence of free electrons which which can move freely and conduct electricity . In insulators there are no free electrons and in that case it cannot conduct electricity.

Conductor Definition:

A conductor is an object or kind of material in physics and electrical engineering that permits charge (electric current) to travel in one or more directions. Metal materials are common electrical conductors. The materials or substances that allow electricity to flow through them are referred to as conductors. Furthermore, conductors allow heat to pass through them. Metals, the human body, the Earth, and animals are all examples of conductors. The human body is an excellent conductor.

The body comes to momentary rest at time t = sqrt(2/(3b*w(0)^2)).

The angular acceleration of the body is given by bt^3, and since w(0)>0, the angular velocity is increasing. At some point, the body will reach its maximum angular velocity and then start to slow down.

The body will come to momentary rest when its angular velocity is zero. Using the formula for angular velocity, w = w(0) + integral(bt^3), and setting it equal to zero, we can solve for the time t. Simplifying the equation yields t = sqrt(2/(3bw(0)^2)). Therefore, the body comes to momentary rest at time t = sqrt(2/(3bw(0)^2)).
