A proton is placed 100 nm from a helium nucleus. The gravitational force pulls the proton and nucleus
together, while the electric force pushes them apart. Which force is stronger and by how much?

The volume ratio that should theoretically travel the furthest distance is the one with the highest amount of reactant.

1. Understand the relationship: The statement mentions that the amount of each reactant in the rocket is directly proportional to the volume of gas bubbled into the rocket. This means that as the volume of gas increases, the amount of reactant also increases.

2. Consider the rocket propulsion: In a rocket, the reactants undergo a chemical reaction that produces a high-pressure gas. This gas is expelled out of the rocket's nozzle, generating a reactive force known as thrust. The thrust propels the rocket forward.

3. Importance of reactant amount: The amount of reactant directly affects the quantity of gas produced during the chemical reaction. More reactant means a larger volume of gas is generated, leading to a greater expulsion of gas and a stronger thrust.

4. Predicting the furthest distance: Based on the above understanding, the volume ratio that will theoretically travel the furthest distance is the one with the highest amount of reactant. This is because a larger amount of reactant results in a higher volume of gas, which generates more thrust, propelling the rocket over a greater distance.

Answer:

Explanation:

To determine the velocity of the balloon, we can use the formula for the magnetic force on a charged particle moving in a magnetic field:

F = qvB

Where:

F is the magnetic force,

q is the charge,

v is the velocity of the balloon, and

B is the magnetic field strength.

Given:

F = -8.11 x 10^-10 N (West)

q = -0.973 μC = -0.973 x 10^-6 C (the negative sign indicates the charge is negative)

B = 5.01 x 10^-5 T

We can rearrange the formula to solve for v:

v = F / (qB)

Substituting the given values:

v = (-8.11 x 10^-10 N) / (-0.973 x 10^-6 C * 5.01 x 10^-5 T)

v ≈ 16.6 m/s

Therefore, the velocity of the balloon is approximately 16.6 m/s. Option (d) is the correct answer.

The greatest upward acceleration be  2.0 m/s².

Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).

Mass of the elevator: m = 1000.0 kg.

The cable can sustain maximum force R= 12000.0 N.

If the maximum upward acceleration of the elevator be a, then equation of motion be:

R = mg + ma [ g = acceleration due to gravity = 10  m/s²

⇒ a =  R/m -g

⇒ a = 12000/1000 - 10

⇒ a = 2.0 m/s²

Hence, the greatest upward acceleration be  2.0 m/s² that can be given the elevator without breaking the cable.

Answer:

The acceleration of the motorbike as it came to a stop was -8.78 m/s² (NOTE: Negative sign indicates deceleration)  

Explanation:

From the question,

A motorbike is traveling to the left with a speed of 27.0 m/s.

This is the initial speed, that is, initial speed = 27.0 m/s

Also, from the question,

The rider slams on the brakes and the bike skids 41.5 m, that is, the bike covers a distance of 41.5 m after the rider slams on the brakes.

Distance = 41.5 m

To determine the acceleration of the motorbike as it came to a stop,

Since, the bike came to a stop, then, the final speed is 0 m/s

From one of the equations of motion for linear motion

v² = u² + 2as

Where v is the final speed (velocity)

u is the initial speed (velocity)

a is the acceleration

and s is the distance

From the question

v = 0 m/s

u = 27.0 m/s

s = 41.5 m

Putting these into the equation

v² = u² + 2as

0² = 27.0² + (2×a×41.5)

0 = 729.0 + 83a

83a = -729.0

a = -729.0 / 83

a = -8.78 m/s² (NOTE: Negative sign indicates deceleration)

Answer:

The momentum bar chart is a tool used to track the changes in momentum of objects in a system over time.

(a) With one cart as the system:

Initial Momentum: m1v1

Final Momentum: m1v1'

Change in Momentum: m1(v1' - v1)

(b) With both carts as the system:

Initial Momentum: m1v1 + m2v2

Final Momentum: m1v1' + m2v2'

Change in Momentum: (m1 + m2)(v1' + v2' - v1 - v2)

The above expressions represent the changes in momentum of the carts, where m1 and m2 are the masses of the carts, v1 and v2 are their initial velocities, and v1' and v2' are their final velocities. The expressions can be used to calculate the net force acting on the carts using Newton's second law, F = Δp/Δt, where Δp is the change in momentum and Δt is the change in time.

Physical quantities that can be calculated from this scenario include the initial and final momentum of the carts, the change in momentum, the net force acting on the carts, and the acceleration of the carts.

The planet that moves the fastest in a solar system is the planet nearest the Sun.

The correct option is C. The Planet Nearest The Sun.

What is a Solar System?

A solar system is a collection of planets, moons, comets, asteroids, and other objects that revolve around a single star. The sun is the center of our solar system, and it includes all of the matter and energy that orbits around it, including Earth and all the other planets.

Sun, the star around which Earth and the other planets of the solar system revolve, has a huge gravitational field. Planets move around the sun in a fixed orbit at varying speeds, depending on their distance from the sun. Because planets are closer to the sun, their gravitational pull is greater, resulting in a faster orbital speed for them.

The planet nearest the sun in the solar system is Mercury. Due to its proximity to the sun, it orbits at a speed of around 48 km/s, making it the fastest planet in the solar system, with an orbital period of 88 Earth days.

Answer:

 V₁ = 6 V ,  V₂ = V₃ = 3 V

Explanation:

To solve this circuit we must remember that there are two fundamental types of construction in series and parallel.

* a serial circuit there is only one path for current

in this circuit the constant current in the entire circuit and the voltage is the sum of the voltage of each term

* Parallel circuit in this there are two or more paths for the current

in this circuit the voltage is constant and the east is divided between each branch

with these principles let's analyze the proposed circuit

The DC battery is in parallel with resistor R1 and the equivalent of the other branch,

as in a parallel circuit the voltage is constant

               V₁ = 6 V

in the other branch (23) it forms a series construction, where the current is constant

               6 = iR₂ + iR₃

as they indicate that each resistance has the same value

              6 = 2 iR

              V = V₂ = V₃ = 3 V

The angle is 34.4°.

The radius of a circle and the central angle determine the length of an arc. We are aware that the arc length is equivalent to the circumference for an angle of 360 degrees (2π). As the proportion between angle and arc length is constant, we can say that:

                                 L / θ = C / 2π

As circumference C = 2πr,

L / θ = 2πr / 2π

L / θ = r

We find out the arc length formula when multiplying this equation by θ:

L = r * θ

The arc length is equal to the radius multiplied by the central angle.

Radius of the circle, r = 2.70m

Length of the arc, L = 1.60 m

L = rθ

θ = L / r

  = 1.60 / 2.70

  = 0.6 rad

θ = (0.6 rad × 180° ) / π rad

  = 34.4°

The power of the contact lenses that will enable the nearsighted physicist to see very distant objects clearly is -1.11 diopters.

To calculate the power of the lens, we use the formula:

Power = 1/focal length

The focal length is the distance at which the physicist can see things clearly, which is 90 cm or 0.9 m.

Plugging this into the formula, we get:

Power = 1/0.9 = 1.11 diopters

However, since the physicist is nearsighted, the power of the lens should be negative. Therefore, the power of the contact lenses is -1.11 diopters.

In summary, a contact lens with a power of -1.11 diopters will enable the nearsighted physicist to see very distant objects clearly.

The initial kinetic energy ki of the two-disk system is Kf = Ki - 0.5μmgr²

The moment of inertia (Ir) and initial kinetic energy (Ki) of the two spinning discs can be used to express the final rotating kinetic energy, or Kf, of the system. We may relate the initial and final kinetic energies using the theory of mechanical energy conservation because friction prevents the conservation of rotational kinetic energy.

According to the conservation of mechanical energy concept, a system's overall mechanical energy stays constant in the absence of outside forces. Friction in this situation is an outside force that drains energy and lowers rotational kinetic energy.

Mathematically, we can express this principle as:

Ki + Work done by external forces = Kf

As mentioned, the work done by external forces, which is due to friction, causes a decrease in the rotational kinetic energy. Therefore, we can write:

Work done by external forces = -ΔK

where ΔK represents the change in kinetic energy due to friction. Substituting this into the conservation of mechanical energy equation, we get:

Ki - ΔK = Kf

Now, using the moment of inertia (Ir) and the starting kinetic energy (Ki), we may express the change in kinetic energy caused by friction. The frictional force multiplied by the distance across which it acts equals the work done by friction. The frictional force can be calculated by multiplying the normal force (N) exerted by the two discs by the coefficient of friction (). The weight of the discs, which is equal to their mass (m) times their gravitational acceleration (g), can be used to represent the normal force. The radius (r) of the discs determines the distance across which friction acts.

ΔK = μNrg

Substituting this into the equation for Kf, we get:

Ki - μNrg = Kf

Now, we can express the normal force (N) in terms of the mass (m) of the disks:

N = mg

Ki - μmgr = Kf

Ir = 1/2mr²

Kf = Ki - (1/2)μmgr²

Using the equation final velocity = beginning velocity + acceleration * time, the final velocity of this bus after two minutes is determined. Symbolically, v is represented as follows: vi = 60 km/h, a = 5 m/s2, and t = 2 minutes. First, we must translate 60 km/h into m/s. 50/3 m/s is equal to 60 km/h or 60,000 m/36 seconds.

When determining the final velocity, v

v = vi + a * t

120 seconds at v = 50/3 m/s + 5 m/s2

v = 50/3 m/s + 600 m/s

v = 16.67 m/s + 600 m/s

v = 616.67 m/s

After two minutes, the bus's speed is 616.67 m/s. For a bus, it is a pretty implausible velocity. The speed of this object is 2,220 km/h, exceeding the speeds of both air and jet aircraft. Your acceleration time should have been capped at 20 seconds or less.
