which function can be used to find the velocity at the bottom of the pendulum released from the same angle for any period, p?
Answers
The function that can be used to find the velocity at the bottom of the pendulum released from the same angle for any period, p is v = π√(L/g). The correct option is B.
This equation can be used to calculate the velocity at the bottom of a basic pendulum (when it hits its lowest point). In the equation, v stands for velocity, L for pendulum length, and g for gravitational acceleration.
The length of the pendulum and the acceleration brought on by gravity both affect the velocity at the bottom of the pendulum.
We may determine the link between these variables by taking the square root of the ratio L/g, which leads to the right equation v = π√(L/g).
The velocity at the bottom of a pendulum launched from the same angle can be determined using this equation for any period, p.
Thus, the correct option is B.

61) What is the efficiency of an ideal Carnot engine operating between a reservoir in which ice and water coexist, and a reservoir in which water and steam coexist? The pressure is constant at 1.0 atm for both reservoirs.
A) 27%
B) 0.27%
C) 100%
D) 1.0%
E) 15%
Answers
The efficiency of an ideal Carnot engine operating between a reservoir in which ice and water coexist, and a reservoir in which water and steam coexist is 27%.
The efficiency of an ideal Carnot engine depends only on the temperatures of the two heat reservoirs between which it operates, and is given by the expression: efficiency = 1 - (Tc/Th) where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir. In this case, the cold reservoir is at 0°C (273 K) and the hot reservoir is at 100°C (373 K), the maximum temperature at which water and steam coexist at 1.0 atm pressure. Therefore: efficiency = 1 - (273/373) = 0.267 or 26.7% (approximately).

Answers
ANSWER:
a) 5 V
b) 8.33 A
c) step-up transformer
STEP-BY-STEP EXPLANATION:
a)
To calculate the input voltage it would be:
\(\begin{gathered} V_{\text{ in}}=\frac{P}{I} \\ V_{\text{ in}}=\frac{100}{20}=5\text{ V} \end{gathered}\)b)
To calculate the output current it would be:
\(\begin{gathered} I_{\text{out}}=\frac{P}{V} \\ I_{\text{out}}=\frac{100}{12}=8.33\text{ A} \end{gathered}\)c)
We have to:
Step-up transformer increase the output voltage.
Step-down transformer reduces the output voltage.
In this case, the voltage goes from being 5 V to being 12 V, therefore the output voltage increases, which means that it would be a step-up transformer.

Answers
Hi, to answer your question regarding the comparison of the magnitudes of kinetic energy (K_A and K_B) of puck A and puck B when they reach the finish line, we need to consider the following steps:
1. Kinetic energy is defined as KE = 0.5 * m * v^2, where m is the mass of the object, and v is its velocity.
2. In order to compare K_A and K_B, we need to know the masses and velocities of both pucks A and B at the instant they reach the finish line.
Since the question does not provide any information about the masses and velocities of the pucks, we cannot determine whether K_A is equal to, greater than, or less than K_B. Therefore, the correct answer is: "You need more information to decide."

The state of Ohio can regulate building contractors and building codes in the state under its Group of answer choices police powers. commerce power. system of checks and balances. entitlement to full faith and credit
Answers
The state of Ohio can regulate building contractors and building codes in the state under its police powers.
The state of Ohio, like any other state in the United States, has the authority to regulate various aspects of public safety, health, and welfare under its police powers. Police powers grant states the ability to create and enforce laws that promote and protect the well-being of their citizens. In the context of building contractors and building codes, Ohio can exercise its police powers to establish regulations and standards that ensure the safety and structural integrity of buildings within its jurisdiction.
By regulating building contractors, Ohio can require licensing, certification, and adherence to specific qualifications or standards. This helps ensure that contractors possess the necessary skills and expertise to construct buildings safely. Building codes, on the other hand, provide guidelines and requirements for construction practices, materials, structural integrity, fire safety, and other relevant aspects. These codes serve to protect occupants and the general public by promoting safe and reliable construction practices.
The exercise of police powers in regulating building contractors and building codes is an essential function of state governments to safeguard public safety and welfare. It allows the state of Ohio to establish and enforce standards that promote secure and reliable construction practices while ensuring the well-being of its residents.

The component form of the velocity of the airplane is (-102.9 km/hr, 280.7 km/hr). This means the airplane is moving approximately 102.9 km/hr to the west and 280.7 km/hr to the north.
To find the component form of the velocity of the airplane, we need to break down the given velocity into its horizontal and vertical components.
Given that the airplane is traveling at a speed of 300 km/hr in the direction 20° west of north, we can represent this velocity as follows:
Magnitude of the velocity = 300 km/hr
Direction of the velocity = 20° west of north
To find the horizontal component, we need to determine the projection of the velocity vector onto the positive x-axis (east direction). Since the direction is west of north, the horizontal component will be negative. Using trigonometry, we can calculate:
Horizontal component = 300 km/hr * sin(20°) ≈ -102.9 km/hr
To find the vertical component, we need to determine the projection of the velocity vector onto the positive y-axis (north direction). Since the direction is north, the vertical component will be positive. Using trigonometry, we can calculate:
Vertical component = 300 km/hr * cos(20°) ≈ 280.7 km/hr
Therefore, the component form of the velocity of the airplane is (-102.9 km/hr, 280.7 km/hr). This means the airplane is moving approximately 102.9 km/hr to the west and 280.7 km/hr to the north.

a photon is absorbed by a hydrogen atom in the ground state. if the electron is boosted from to the n = 6 , what was the energy of the absorbed photon? give your answer in electron volts (ev).
Answers
The energy of the absorbed photon was approximately 12.094 electron volts (eV).
When a photon is absorbed by a hydrogen atom in the ground state, the electron is excited to a higher energy level. In this case, the electron is boosted to the n=6 energy level. To calculate the energy of the absorbed photon, we can use the Rydberg formula:
ΔE = -R_H ×(1/n_f² - 1/n_i²)
Where ΔE is the change in energy, R_H is the Rydberg constant for hydrogen (approximately 13.6 eV), n_f is the final energy level (n=6), and n_i is the initial energy level (n=1, ground state).
ΔE = -13.6 × (1/6² - 1/1²)
ΔE ≈ 12.094 eV

Answers
Answer:
η₁ = 2.6
Explanation:
Here, we will use snell's law to calculate the refractive of the substance:
\(\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}\)
where,
η₁ = refractive index of first substance = ?
η₂ = refractive index of second substance = 1.5
θ₁ = angle of incidence = 30°

Bullet 2 has twice the mass of bullet 1. Both are fired so that they have the same speed. If the kinetic energy of bullet 1 is K, what is the kinetic energy of bullet 2
Answers
The kinetic energy of the bullet is 2K, twice the kinetic energy of bullet 1.
The kinetic energy of an object is the energy possessed due to its motion. The kinetic energy of an object of mass m moving with a velocity v is given by K = mv²/2 ( in joules)
Given: kinetic energy of bullet 1 = K =m₁×v²/2
mass of bullet 2, m₂ = twice of mass of bullet 1, m₁
m₂ = 2 × m₁
the kinetic energy of bullet 2 is = m₂ × v²/2 , since speed are same.

• if one gear has an input torque of 1000 lb-ft, what is the torque of the other gear
Answers
The output torque of the second gear will be 3000 lb-ft.
Gear is a toothed wheel or cylinder that is used to transmit rotational force or motion from one component to another. Gears are commonly used to change the speed or direction of a rotating force, increase or decrease torque, and to alter the amount of force between two components. Gears are found in many everyday machines, including cars, bicycles, clocks, and other machines.
The torque of the other gear is determined by the gear ratio. If the gear ratio is 3:1, then the output torque of the second gear will be \(\frac{ 1000 lb-ft}{3} = 333.3 lb-ft.\)
If the gear ratio is 1:3, then the output torque of the second gear will be\(1000 lb-ft*3 = 3000 lb-ft\)
Therefore,then the output torque of the second gear will be 3000 lb-ft.
