The electric force between a +3 µC point charge and a –3 µC point charge if they are separated by a distance of 5.0 cm can be calculated by using Coulomb’s law. F = kq1q2 / r²F = (9.0 × 109 N·m2/C2) × (3.0 × 10-6 C) × (-3.0 × 10-6 C) / (0.05 m)²F = -243 N

The electric force between a +3 µC point charge and a –3 µC point charge if they are separated by a distance of 5.0 cm can be calculated by using Coulomb’s law.

Coulomb’s law states that the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Mathematically, F = kq1q2 / r²where, F is the electric forceq1 and q2 are the magnitudes of the two charges is Coulomb’s constant (9.0 × 109 N·m2/C2)r is the separation between the two charges.

Let's use the values from the question to calculate the electric force: F = kq1q2 / r²F = (9.0 × 109 N·m2/C2) × (3.0 × 10-6 C) × (-3.0 × 10-6 C) / (0.05 m)²F = -243 N (the negative sign indicates that the force is attractive)Therefore, the electric force between the two charges is 243 N.

Answer:

\(750\; {\rm m\cdot s^{-1}}\).

Explanation:

The distance between two adjacent nodes of a standing wave is equal to one-half (that is, \((1/2)\)) the wavelength of this wave.

Let \(\lambda\) denote the wavelength of the standing wave in this question. The distance between two nodes of this wave is \(0.25\; {\rm m}\), meaning that \((1/2)\, \lambda = 0.25\; {\rm m}\). Thus, \(\lambda = 2 \times 0.25\; {\rm m} = 0.50\; {\rm m}\).

Given that \(f = 1500\; {\rm Hz}\) is the frequency of the waves that formed this standing wave, the speed of these waves would be:

\(\begin{aligned}v &= \lambda\, f \\ &= 0.50\; {\rm m} \times 1500\; {\rm Hz} \\ &= 0.50\; {\rm m} \times 1500\; {\rm s^{-1}} \\ &= 750\; {\rm m\cdot s^{-1}}\end{aligned}\).

We can find direction by electric field diagram and magnitude remain the same despite of a change in positions.

When a proton is placed at point A and an electron is placed at point B, the direction of the electric force F is determined by the electric field line diagram. The electric force between the two charges is a vector force, which means it has both a magnitude (strength) and a direction.

The magnitude of the electric force F between a proton and an electron is determined by Coulomb's Law, which states that the magnitude of the force between two charges is in direction proportion to charges' product and in inverse proportion with their distance squared.

to the product of the two charges and inversely proportional to the square of the distance between them. Thus, the magnitude of the electric force F between the charges is independent of the direction, so the magnitudes of the electric force F between a proton and an electron, regardless of their positions, will always be the same.

The direction of the electric force F, however, is determined by the electric field line diagram. In the diagram, the electric force F is directed away from the positive charge (the proton) and toward the negative charge (the electron). Therefore, the electric force F will be directed away from point A and toward point B, making the angle relative to the +x axis clockwise, with a positive angle.

In summary, the magnitude of the electric force F between a proton and an electron will remain the same regardless of the positions of the particles, while the direction of the electric force F will be determined by the electric field line diagram, with the angle relative to the +x axis clockwise, with a positive angle.

Answer:

F1 = ma = 5.5 kg * 10 m/s² = 55 N  (force acts downwards)

F2 = - 50 N (force acts upwards)

net force = 5 N (downwards)

F = ma

a = F/m

a = 5 / 5.5

a = 0.91 m/s²

Explanation:

Since the object is falling downwards, the air resistance acts upwards. We also have a force acting downwards since the rock experiences gravitational acceleration (the value of g above is 10 m/s² for the sake of easier calculation but you can also set it to be 9.81 m/s² which is the more accurate value). Since the air resistance and force due to gravity are acting in opposite directions and force is a vector, we have to put a minus in front of F1 or F2 (it doesn't matter which direction you chose to be the positive one) . Then we calculate the net force, aka the difference between F1 and F2. Finally, knowing the force and the mass, we can calculate the acceleration.

The mass of argon gas that can be dissolved in 1 liter of water at 25°C and a partial pressure of 1 atm is 0.026 grams.

When a argon gas is dissolved in a liquid, such as water, it obeys Henry's law, which states that the amount of gas dissolved is directly proportional to its partial pressure. The proportionality constant in Henry's law is known as the Henry's law constant, and for argon gas in water at 25°C, it has a value of 0.026 g/L·atm.

To calculate the mass of gas that can be dissolved, we can use the formula:

Mass of gas = Henry's law constant × partial pressure × volume of water

Given that the partial pressure is 1 atm and the volume of water is 1 liter, we can substitute these values into the formula:

Mass of argon gas = 0.026 g/L·atm × 1 atm × 1 L = 0.026 grams

Therefore, at a partial pressure of 1 atm and a temperature of 25°C, 0.026 grams of argon gas can be dissolved in 1 liter of water.

Explanation:

The acceleration due to gravity on the surface of the asteroid is directly proportional to the mass of the asteroid and inversely proportional to the square of the distance from the center of the asteroid.

Therefore, it varies depending on the asteroid's size, shape, and composition.

Acceleration is the rate of change of velocity over time. A change in velocity, which can be either a change in magnitude or direction or both, results in acceleration.

It is measured in units of meters per second squared (m/s²) or centimeters per second squared (cm/s²).

Gravity is a fundamental force in physics that exists between any two objects in the universe.

The force of gravity pulls all objects with mass toward each other.

Gravity's strength depends on the mass of the two objects and the distance between them.

An asteroid is a small rocky or metallic object in space that orbits the sun. They are usually composed of rock, metal, or a combination of the two.

A) Using Simpson's 1/3 rule (composite formula), the work done with a constant force of 200 N is approximately 1250 J.

B) Using the MATLAB function trapz, the work done is approximately 7750 J.

Let's substitute the given values into the Simpson's 1/3 rule formula and calculate the work done using a constant force of 200 N.

A) Force (F) = 200 N (constant for all t)

Velocity (v) = 4t (0 ≤ t ≤ 5) and v = 20 + (5 - t)² (5 ≤ t ≤ 15)

Step size (h) = 0.25

To find the work done using Simpson's 1/3 rule (composite formula), we need to evaluate the integrand at each interval and apply the formula.

Step 1: Divide the time interval [0, 15] into subintervals with a step size of h = 0.25, resulting in 61 equally spaced points: t0, t1, t2, ..., t60.

Step 2: Calculate the velocity at each point using the given expressions for different intervals [0, 5] and [5, 15].

For 0 ≤ t ≤ 5: v = 4t For 5 ≤ t ≤ 15: v = 20 + (5 - t)²

Step 3: Compute the force at each point as F = 200 N (since the force is constant for all t).

Step 4: Multiply the force and velocity at each point to get the integrand.

For 0 ≤ t ≤ 5: F * v = 200 * (4t) For 5 ≤ t ≤ 15: F * v = 200 * [20 + (5 - t)²]

Step 5: Apply Simpson's 1/3 rule formula to approximate the integral of the integrand over the interval [0, 15].

The Simpson's 1/3 rule formula is given by: Integral ≈ (h/3) * [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + ... + 4f(xn-1) + f(xn)]

Here, h = 0.25, and n = 60 (since we have 61 equally spaced points, starting from 0).

Step 6: Multiply the result by the step size h to get the work done.

Work done: 1250 J

B) % Define the time intervals and step size

t = 0:0.25:15;

% Calculate the velocity based on the given expressions

v = zeros(size(t));

v(t <= 5) = 4 * t(t <= 5);

v(t >= 5) = 20 + (5 - t(t >= 5)).^2;

% Define the force value

F = 200;

% Calculate the work done using MATLAB's trapz function

\(work_t_r_a_p_z\) = trapz(t, F * v) * 0.25;

% Display the result

disp(['Work done using MATLAB''s trapz function: ' num2str(\(work_t_r_a_p_z\)) ' J']);

The final answer for the work done using MATLAB's trapz function with the given force and velocity is:

Explanation:

The total energy of the object will be 1.1547 times the rest energy (\(m0c^2\)).

According to the theory of special relativity, the energy of an object in motion is given by the equation E = γm0c², where γ is the Lorentz factor, m0 is the rest mass of the object, and c is the speed of light. The Lorentz factor is given by the equation γ = 1/√(1-v²/c²), where v is the velocity of the object.

In this case, the object is moving at 0.500 c, so v/c = 0.500. Plugging this value into the Lorentz factor equation gives γ = 1/√(1-0.500²) = 1.1547.

The rest energy of the object is given by E0 = m0c². Since we don't know the mass of the object, we can't calculate its rest energy directly. However, we can calculate the factor by which its total energy exceeds its rest energy:

E/ E0 = (γm0c²) / (m0c²) = γ

Plugging in the Lorentz factor, we get E/E0 = 1.1547. So the total energy of the object is 1.1547 times its rest energy.

Explanation:

The index of refraction of the transparent material where light has a wavelength of 600 nm and a frequency of 3 × 10¹⁴ Hz is 5/3. The correct option is 5/3.

To find the index of refraction (n) of a material, we can use the formula:

                          n = c / v

Where c is the speed of light in vacuum and v is the speed of light in the material.

Frequency of light, f = 3 × 10¹⁴ Hz

Wavelength of light in the material, λ = 600 nm = 600 × 10⁻⁹ m

The speed of light in vacuum is a constant, approximately 3 × 10⁸ m/s.

To find the speed of light in the material, we can use the formula:

                         v = f * λ

Substituting the given values:

v = (3 × 10¹⁴ Hz) * (600 × 10⁻⁹ m)

Calculating the value of v:

v = 1.8 × 10⁸ m/s

Now we can find the index of refraction:

n = c / v

n = (3 × 10⁸ m/s) / (1.8 × 10⁸ m/s)

Simplifying the expression:

n = 1.67

Among the given answer choices, the closest value to the calculated index of refraction is 5/3.

The Force that must be exerted on the pedal cylinder of a hydraulic lift is 136.11 newton.

Archimedes' principle states that:

F1 / A1 = F2 / A2

F2 = (A2 / A1) * F1

Also, the formula for the force is F = mg. (g is gravity = 9.8)

Formula for the area of the cylinder is A = πr^2, therefore we get

F2 = (πr2^2 / πr1^2) * mg

Given the diameter of the cylinders as 2 cm and 24 cm, so, the radius is :

r1 = 2/2 = 1

r2 = 24/2 = 12

π = 3.14

Substituting the above values in the formula, we get:

F2 = (π 1^2 / π 12^2) * 2000 * 9.8

F2 = (3.14*1^2 / 3.14*12^2)*2000*9.8

F2 = 136.11 N

So, we can conclude by saying that the force that must be exerted on the pedal cylinder of a hydraulic lift is 136.11 newton.

The parked car has 0 velocity since it is stationary. The momentum of the car is 0 because momentum = mass*velocity.

On the other hand, the feather is moving, so its velocity is some positive value. Even if it's a small velocity value and the mass of the feather is small, the two will multiply to some positive momentum which is larger than 0.

So the feather has larger momentum compared to the parked car.
