The two balls will collide in 2 seconds if they start 30 feet apart.

To calculate the time it takes for the two balls to collide, we first need to calculate the distance between them. The distance between two objects is equal to their speed multiplied by the time it takes them to travel that distance: velocity × time = distance

In this case, we want our distance formula to be 3 ft/s × 2 seconds = 6 ft

Then, using our formula, we can find how long it would take for the two balls to collide by plugging in our numbers: 6 ft + 5 ft = 11 ft. When we add 11 ft into both sides of our equation, we get 0 seconds, which means that when these two balls collide, they collide at the same time.

The answer option which is an example of the law of multiple proportions is: B) Two different compounds formed from carbon and oxygen have the following mass ratios: 1.33 g O: 1 g C and 2.66 g O: 1 g C.

The Law of Multiple Proportions is also referred to as Dalton's Law and it states that when two chemical elements combine to form more than one chemical compound, the masses (weights) of one chemical element that combine with a fixed mass (weight) of the other chemical element will always be in a ratio of small whole numbers.

According to the Law of Multiple Proportions, when two chemical elements combine to form two different chemical compound, the masses (weights) of one chemical element that combine with 1 gram of the other chemical element can be expressed as a ratio of small whole numbers.

For example, carbon and oxygen react to form either carbon monoxide and carbon dioxide.

Carbon monoxide (CO):

12 grams of C = 16 grams of O.

1 gram of C = 1.33 gram of O.

Carbon dioxide (\(CO_2\)):

12 gram of C = 32 grams of O.

1 gram of C = 2.66 gram of O.

Ratio of oxygen (O) = 16:32 = 1:2 (Law of Multiple Proportions).

A brighter light source will result in a larger voltage drop across the resistor in a circuit with a phototransistor because the increased current flowing through the circuit causes a larger voltage drop according to Ohm's law.

If there is a single resistor in series with a phototransistor, a brighter light source would result in a larger voltage drop across the resistor.

The reason for this is that when the phototransistor is exposed to a brighter light source, more current will flow through the circuit because the phototransistor allows more current to pass through in the presence of a brighter light.

This increased current will cause a larger voltage drop across the resistor because the voltage drop across a resistor is directly proportional to the current flowing through it according to Ohm's law.

Ohm's law states that the voltage drop (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor:

V = IR.

Therefore, if the current through the circuit increases due to the brighter light source, the voltage drop across the resistor will also increase because the resistance of the resistor remains constant.

The object's velocity after the force ends equals 3.0 m/s, moving to the right.

Velocity is described as a vector measurement of the charge and path of motion. Placed truly, speed is the velocity at which something moves in one course. The velocity of an automobile travelling north on a chief parkway and the velocity of a rocket launching into the area can each be measured using speed.

The distinctive styles of velocities are uniform speed, variable velocity, common pace and immediate pace. Uniform velocity: A body is stated to be shifting with uniform speed if its average pace among any two factors along its course is equal in importance as well as path.

It happens because NADH enters the electron transport chain earlier as compared to the FADH2.

What is an electron?

The electron is a subatomic particle with the symbol e and a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are members of the lepton particle family's first generation, are typically regarded to be elementary particles. The mass of an electron is around 1/1836 that of a proton. The electron has a half-integer intrinsic angular momentum (spin) that is described in terms of the reduced Planck constant, among its quantum mechanical features. Since electrons are fermions, the Pauli exclusion principle states that no two electrons may be in the same quantum state. Electrons, like other elementary particles, have characteristics of both waves and particles.

The oxidation of NADH produces more ATP than the oxidation of FDH2 because NADH enters the electron transport chain sooner than FADH2. The oxidation of both NADH and FDH2 leads in the synthesis of ATP molecules.

Explanation:

When you change the thickness of the wire in a circuit, option B. the resistance (R) and current (I) will also change, but the voltage (V) will remain constant.

The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area (thickness). As the thickness of the wire changes, the cross-sectional area changes, which in turn affects the resistance. Thicker wires have a larger cross-sectional area, resulting in lower resistance, while thinner wires have a smaller cross-sectional area, resulting in higher resistance. Therefore, changing the thickness of the wire will cause a change in resistance.

According to Ohm's Law (V = IR), the voltage (V) in a circuit is equal to the product of the current (I) and the resistance (R). If the voltage is kept constant, and the resistance changes due to the thickness of the wire, the current will also change to maintain the relationship defined by Ohm's Law. When the resistance increases, the current decreases, and vice versa.

However, it's important to note that changing the thickness of the wire will not directly affect the voltage. The voltage in a circuit is determined by the power source or the potential difference applied across the circuit and is independent of the wire thickness. As long as the voltage source remains constant, the voltage across the circuit will remain constant regardless of the wire thickness. Therefore, the correct answer is option B.

The other answer is correct: the act of hitting a ball with a bat creates a sound. You see the act of hitting almost immediately because light travels very fast. The sound on the other hand travels much slower. So if you sit high in the stadium, the sound has to travel for a long distance before reaching you. That is why you hear the sound after you see the ball being hit.

b. upthrust. The upward force exerted by a gas or liquid is called upthrust.

This force is generated due to the content loaded and the pressure exerted by the gas or liquid. A fluid's buoyancy, also known as upthrust, opposes the weight of an item that is partially or completely submerged by exerting an upward push. The weight of the fluid on top causes pressure in a fluid column to rise with depth. As a result, the pressure at the bottom of a fluid column is higher than at the top. Similar to this, an object submerged in a fluid experiences greater pressure at its bottom than it does at its top. A net upward force is exerted on the item as a result of the pressure differential.

As oxygen levels increase, polarization tends to decrease. This is because oxygen is a highly electronegative element, meaning it has a strong attraction for electrons.

As oxygen molecules are introduced to a system, they will attract electrons away from other molecules, causing an overall decrease in polarization. This can have various effects on the system, depending on the specific context. For example, in certain chemical reactions, decreased polarization can lead to a decrease in reactivity or a decrease in the strength of intermolecular forces. However, in other contexts, such as in biological systems, decreased polarization may be beneficial, as it can help to stabilize important molecules like proteins and DNA. Overall, the relationship between oxygen levels and polarization is an important factor to consider in many different scientific fields, and can have a significant impact on the behavior of systems ranging from the smallest chemical reactions to the largest ecosystems.

For the instant represented, the velocity of A is VA = 5.5j in./sec and the tangential acceleration of B is (aB)t = - 7.2i in./sec². The expression vector can be seen as ac = α × OC = (-7.2/R)i × (-Rj) = 7.2j

To find the vector expressions for angular velocity (ω) and angular acceleration (α) of the disk, we can use the following relationships:

Angular velocity (ω) = dθ/dt

Angular acceleration (α) = dω/dt

Given:

Velocity of point A (VA) = 5.5j in./sec

Tangential acceleration of point B (aB)t = -7.2i in./sec²

The velocity VA is perpendicular to the radius OA, which means it is tangential to the circular path. Therefore, the direction of ω is along the positive z-axis (out of the plane of the paper).

So, we have:

ω = ωk

Next, we can find the angular acceleration α using the formula:

α = (aB)t / R

The direction of α will depend on the direction of the tangential acceleration and the orientation of the coordinate system. Since aBt is in the negative x-direction, we have:

α = (-7.2i) / R = (-7.2/R)i

Finally, to find the acceleration ac at point C, we can use the relationship:

ac = α × OC

OC is in the negative x-direction, so the cross product will result in a vector pointing in the negative y-direction. Therefore, we have:

ac = α × OC = (-7.2/R)i × (-Rj) = 7.2j

In summary:

ω = ωk
