Electrons are the charge carriers of an electric circuit. They carry negative charge through the wire from one terminal of a battery to another. True or false?

Answer:

The capacitance of the other capacitor is 1333.3 pF.

Explanation:

C' = 200 pF, V' = 100 V, C'' , V''= 0

Common potential, V = 60 V

Use the formula of the common  potential

\(V = \frac{C' V' + C'' + V''}{C'+ C''}\\\\60 = \frac{200\times 100 + 0}{200 + C''}\\\\1200+ 6 C''= 2000\\\\C'' = 1333.3 pF\)

The momentum after the collision is 25500 kg⋅m/s. Each object's momentum may change, but the overall momentum must not change.

In Newtonian mechanics, momentum is calculated as the sum of an object's mass and velocity. It has a magnitude and a direction, making it a vector quantity.

The rate of change of a body's momentum is equal to the net force exerted on it, according to Newton's second law of motion. Regardless of the frame of reference, momentum is a conserved quantity in any inertial frame, which means that if an enclosed system is not subject to outside influences, its total linear momentum remains constant.

The formula for calculating momentum is expressed as

momentum = mass x velocity

According to the law of conservation of momentum, initial momentum = final momentum

The formula for initial momentum is

m1u1 + m2u2

where

m1 = mass of first car

u1 = initial velocity of first car

m2 = mass of second car

u2 = initial velocity of second car

From the information given,

m1 = 900

u1 = 0 because it is at rest

m2 =  1700

u2 = 15.0 m/s

Initial momentum = 900 x 0 +  1700 x 15.0 = 25500

Momentum after the collision is 25500 kg⋅m/s

The type of radiation energy that can range several hundred feet and easily penetrate the skin is nonionizing radiation. Option a is the correct answer.

Nonionizing radiation is a type of electromagnetic radiation that has lower energy than ionizing radiation, which includes alpha particles. Examples of nonionizing radiation include radio waves, microwaves, infrared radiation, visible light, and ultraviolet radiation. Ultraviolet radiation can penetrate the skin and cause damage to the DNA in skin cells, which can lead to skin cancer.

Alpha particles, on the other hand, are heavy and positively charged particles that have high energy and can cause damage to biological tissues, but they have a short range and cannot penetrate the skin. They are typically blocked by a sheet of paper or the outer layers of the skin.

Answer:

Static electricity, specifically electrostatic attraction has occurred.

Explanation:

This phenomenon is known as static electricity, which involves the buildup of electric charges on the surface of a material. It can occur when two materials come into contact and then separate, transferring electrons from one material to the other. When you rub the comb against the rabbit fur, you transfer some of the electrons from the fur to the comb, leaving the fur with a positive charge and the comb with a negative charge. This charge separation creates an electric field around the comb and the fur. When you bring the comb and fur near the paper confetti, the negatively charged electrons in the confetti are attracted to the positive charge on the fur and the confetti sticks to the fur. This process is known as electrostatic attraction.

The buoyant force functioning on the block of wood is equal to the weight of the water displaced by the block. According to Archimedes' principle, when an object is submerged in a fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces.

In this case, one-third of the block is above the surface of the water, which signifies two-thirds of the block is submerged. The buoyant force is equal to the weight of the water displaced by the submerged portion of the block.

Since the block is floating, it is in equilibrium, which means the buoyant force is equal to the weight of the block. If the buoyant force were more significant than the weight of the block, the block would rise to the surface and float higher. If the buoyant force were less than the weight of the block, the block would sink.

Therefore, the buoyant force is equal to the weight of the block. Both forces have the same magnitude but act in opposite directions. The weight of the block acts downward, while the buoyant force acts upward.

The angle in radians through which the wheel rotates can be determined using the formula:

Angle (in radians) = (Number of revolutions) × (2π)

Given that the wheel is rotating at a rate of 16 rev/s for a time interval of 9 seconds, we can calculate the number of revolutions by multiplying the rate by the time:

Number of revolutions = (16 rev/s) × (9 s) = 144 rev

Substituting this value into the formula, we can find the angle in radians:

Angle (in radians) = (144 rev) × (2π) = 288π radians

Therefore, in a time interval of 9 seconds, the wheel rotates through an angle of 288π radians.

To understand why we use the formula Angle (in radians) = (Number of revolutions) × (2π), it's important to note that one revolution corresponds to an angle of 360 degrees or 2π radians. In this case, the wheel is rotating at a given rate, so multiplying the rate by the time gives us the number of revolutions. Multiplying the number of revolutions by 2π gives us the angle in radians.

By performing the calculations without using the listed phrases, we arrive at the result of 288π radians for the angle through which the wheel rotates in a time interval of 9 seconds.
