"which forms of light are lower in energy and frequency than the light that our eyes can see"

The current in the circuit from the voltage 1.5 V and the resistance 6 ohm is 0.25 ampere. Thus, option A is correct.

Ohm's law is defined as the current flow in the circuit is directly proportional to the applied voltage in the circuit. Ohm's law is applicable at a constant temperature.

V∝I, where V is the potential difference and I is the current. Ohm's law can also be defined as, V = IR, and R is the resistance of the circuit. The unit of current is ampere(A).

Resistance is defined as the obstruction in current flow and the unit of resistance is ohm(Ω). Resistance is inversely proportional to the current flow. Resistance increases with the decrease of current and vice-versa.

From the given,

Voltage(V) = 1.5 V

Resistance (R) = 6 Ω

Ohm's law, V = IR

V / R = I

I = 1.5 / 6

= 0.25 A

I = 0.25 ampere

Thus, the current flow in the circuit is 0.25 A. Hence, the ideal solution is option A.

Answer:

The answer would be TRUE

Peter and Paul did have a great influence on the early church.

(a) Angular Speed is 140π radians per hour.

(b) The linear speed of a passenger on the Ferris wheel is approximately 3.249 feet per minute.

To find the angular speed of the Ferris wheel in radians per hour, you can use the following formula:

Angular Speed (ω) = (2π * Number of Revolutions) / Time

(a) Angular Speed in Radians per Hour:

Number of Revolutions = 70 revolutions

Time = 1 hour

ω = (2π * 70) / 1

ω = 140π radians per hour

Now, to find the linear speed of a passenger in feet per minute, you need to consider the circumference of the Ferris wheel.

(b) Circumference of the Ferris Wheel:

The diameter of the Ferris wheel is given as 62 feet, so the radius (r) is half of that, which is 31 feet. The circumference (C) of the wheel is given by:

C = 2πr

C = 2π * 31 feet

C ≈ 194.94 feet

Now, to find the linear speed (v) in feet per minute, you can use the formula:

Linear Speed (v) = (Circumference / Time)

Time in this case is 1 hour, which is equivalent to 60 minutes:

v = 194.94 feet / 60 minutes

v ≈ 3.249 feet per minute

Hence, the linear speed of a passenger on the Ferris wheel is approximately 3.249 feet per minute.

Absolute zero is the theoretical lowest temperature at which all molecular motion stops. It's equivalent to -273.15 degrees Celsius or 0 Kelvin.

Absolute zero refers to the lowest possible temperature that can be theoretically achieved. It represents the point at which all molecular motion is presumed to stop, which is choice B in your options. However, this doesn't mean that all forms of energy disappear at this temperature - quantum mechanics tells us that minimal vibrations persist even at this extreme. In practical terms, absolute zero is equivalent to -273.15 degrees Celsius, or 0 on the Kelvin scale (not 273 Kelvin as option D suggests). Neither 0 degrees on the Celsius scale (option A), nor 0 degrees on the Fahrenheit scale (option C), is equivalent to absolute zero.

D) sound is molecules bumping into one another.

Explanation:

Sound waves are longitudinal waves generated by the vibrations of the molecules  of a medium. These oscillations occur in a direction parallel to the direction of propagation of the wave (longitudinal wave), so basically the wave is transmitted by the collisions between the molecules of the medium, and therefore D. is the correct answer. Morevoer, these oscillations create regions of higher density of molecules (called compressions) and regions of lower density of molecules (called rarefactions).

When the current is the same through all the resistors and the batteries of a circuit, you have resistors in series. Option B is correct.

In the series circuit, the amount of current flowing through any component in a series circuit is the same and the sum of the individual resistances equals the overall resistance of any series circuit.

The voltage in a series circuit, the supply voltage, is equal to the total of the individual voltage drops.

Components linked in series share a single “electrical route,” and each component receives the same current, which is equal to the network's current.

When the current is the same through all the resistors and the batteries of a circuit, you have resistors in series.

Hence,option B is correct.

Answer:

D) Spinning a coil of wire near a large magnet.

Explanation:

From Faraday's law of induction, when a conducting coil of wire is placed in changing magnetic flux, an emf is induced which produces current in the coil.

Induced emf is given by:

[tex]e = -\frac{d\phi}{dt}[/tex]

A generator is based on the same principle.

The mechanical energy of rotating coil is converted to electrical energy when current is induced. Thus, the correct option is D) Spinning a coil of wire near a large magnet.

An electric generator converts mechanical energy into electrical energy via electromagnetic induction, which is achieved by spinning a coil of a wire near a large magnet. This process is described accurately in option D of the multiple choice question.

An electric generator operates on the principle of electromagnetic induction, which was discovered by Michael Faraday. It involves the conversion of mechanical energy into electrical energy by spinning a magnet within a coil or spinning a coil within a magnetic field. Therefore, the correct answer to which process transforms mechanical energy into electrical energy in an electric generator is D) Spinning a coil of wire near a large magnet.

This process generates an electromotive force (emf) that results in the flow of electric current. The other options mentioned, such as using wind to spin a magnet around (A), connecting a battery to a coil of wire (B), or turning a wheel that contains electrons (C), do not accurately describe the fundamental operation of an electric generator.

Answer: I believe the answer is: Nuclear processes, but not chemical

Explanation:

To find the final angular velocity of the merry-go-round after the child gets on it, we use the conservation of angular momentum. By setting the initial and final angular momenta equal, we can solve for the final angular velocity. The final angular velocity is found to be approximately 0.301 rev/s.

To find the angular velocity of the merry-go-round after the child gets on it, we need to consider the conservation of angular momentum. The initial angular momentum of the system is equal to the final angular momentum after the child grabs the outer edge. The initial angular momentum of the system is calculated as the product of the moment of inertia of the merry-go-round and its initial angular velocity. The final angular momentum is calculated as the sum of the moment of inertia of the merry-go-round and the child and the final angular velocity.

Let's denote the initial angular velocity of the merry-go-round as ω1, the final angular velocity as ω2, the moment of inertia of the merry-go-round as I1, the moment of inertia of the child as I2, the radius of the merry-go-round as R, the mass of the merry-go-round as M, and the mass of the child as m.

The initial angular momentum is given by:

L1 = I1 * ω1

And the final angular momentum is given by:

L2 = (I1 + I2) * ω2

Setting the initial and final angular momenta equal, we have:

I1 * ω1 = (I1 + I2) * ω2

Rearranging the equation, we can solve for ω2:

ω2 = (I1 * ω1) / (I1 + I2)

Substituting the given values, we have:

ω2 = (120 kg * (1.80 m)^2 * 0.330 rev/s) / ((120 kg * (1.80 m)^2) + (27.5 kg * (1.80 m)^2))

Simplifying the expression, we can calculate the final angular velocity:

ω2 ≈ 0.301 rev/s
