The repulsion force between the two Arkon nuclei when the distance between them is 1x10⁻³μm is approximately 7.4x10⁻¹⁴N. The correct option is d. 7.4x10⁻¹⁴N.

The formula for repulsion force between two Arkon nuclei when the distance between them is given by Coulomb's law. Coulomb's law states that the 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, the law can be expressed as F=kq1q2/r²,

Where F is the force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb's constant.The electric charge of one electron is 1.6x10⁻¹⁹C.

Therefore, the charge of the Arkon nucleus with 18 protons = 18(1.6x10⁻¹⁹) C = 2.88x10⁻₈⁸ CThe force between the two Arkon nuclei can be calculated using the formula above.

F=kq1q2/r²

Substituting the values we have;F = (9x10⁹)(2.88x10⁻¹⁸ C)2/(1x10⁻³ m)2F ≈ 7.4x10⁻¹⁴ N. Therefore, the repulsion force between the two Arkon nuclei when the distance between them is 1x10-3μm is approximately 7.4x10⁻¹⁴N. The correct option is d. 7.4x10⁻¹⁴N.

Answer:

The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.

Explanation:

Weight of the object on the surface of Earth, W = 245 N

On the surface of Earth, acceleration due to gravity, g = 10 m/s²

Weight of an object is given by :

W = mg

m is mass

\(m=\dfrac{W}{g}\\\\m=\dfrac{245\ N}{10\ m/s^2}\\\\=24.5\ kg\)

So, the mass of the object is 24.5 kg

Acceleration due to gravity on Mars, g' = 3.72 m/s²

Weight of the object on Mars,

W' =mg'

W' = 24.5 kg × 3.72 m/s²

= 91.14 N

So, the weight of the object on Mars is 91.14 N.

Given the data in the question;

Weight of object; \(W = 245N\)

Weight the measure of the force of gravity pulling down on a particle or object.

It is expressed as:

\(W = m* g\)

Where m is mass of the object and g is acceleration due to gravity { Acceleration due gravity of Earth \(g_{earth} = 9.8m/s^2\) }

We substitute our values into the equation

\(245N = m * 9.8m/s^2\\\\245kg.m/s^2 = m * 9.8m/s^2\\\\m = \frac{245kg.m/s^2}{9.8m/s^2} \\\\m = 25kg\)

Therefore, mass of the object located near the Earth surface is 25kg

So on planet Mars; \(g = 3.72m/s^2\), we know that mass of the object is \(25kg\)

We substitute into our equation

\(W = m* g\)

\(W = 25kg * 3.72m/s^2\\\\W = 93kg.m/s^2\\\\W = 93N\)

Therefore, the weight of the object on Mars with the given gravity is 93 Newtons.

An object's speed, also known as "v," is the amount by which its position changes over time or by how much it changes per unit of time, making it a scalar number.  

The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance traveled by the object divided by the duration of the period. Velocity and speed are not the same thing.

The parameters of speed are time divided by distance. The metre per second (m/s), the SI measure of speed, is the most widely used unit of speed in daily life.

To determine the power consumption of the circuit at a time 3 2 τ after s has been switched to position b, we need to first understand the circuit diagram. The circuit consists of a capacitor, two resistors, a voltage source, and a switch.

When the switch is in position a, the capacitor charges up to the voltage of the source, which is 12 volts. When the switch is switched to position b, the capacitor starts discharging through the resistors. The time constant of the circuit is given by the formula τ = R1*C, where R1 is the resistance of resistor 1 and C is the capacitance of the capacitor.

In this circuit, the time constant is 8 microseconds. So, at a time 3 2 τ (12 microseconds) after the switch has been moved to position b, the capacitor has discharged by approximately 95% of its initial charge. The voltage across the capacitor is given by the formula Vc = Vo*e^(-t/τ), where Vo is the initial voltage across the capacitor and t is the time since the switch has been moved to position b.

Substituting the values, we get Vc = 12*e^(-1.5) = 5.05 volts. The current flowing through the resistors is given by the formula I = V/R, where V is the voltage across the resistors and R is the resistance of the resistors. Substituting the values, we get I = 5.05/(4+15) = 0.28 amps.

The power consumption of the circuit is given by the formula P = V*I, where V is the voltage across the circuit and I is the current flowing through the circuit. Substituting the values, we get P = 5.05*0.28 = 1.41 watts. Therefore, the power consumption of the circuit at a time 3 2 τ after the switch has been moved to position b is 1.41 watts.

Long-term exposure to loud noises can indeed damage hearing. If a loud machine produces sounds with an intensity level of 110dB, and the intensity were reduced by a factor of 5, the new intensity level would be 92dB. It's important to protect our hearing from loud noises to prevent damage and preserve our ability to hear well.

Long-term exposure to loud noises can indeed damage hearing. If a loud machine produces sounds with an intensity level of 110 dB, and the intensity is reduced by a factor of 5, you would calculate the new intensity level as follows:
New intensity (in watts/m²) = Original intensity / 5
First, you need to convert the original 110 dB to watts/m² using the formula:
Intensity (in watts/m²) = 10^(dB/10) = 10^(110/10) = 10^11 watts/m²
Next, divide the original intensity by 5:
New intensity (in watts/m²) = 10^11 / 5 = 2 x 10^10 watts/m²
Finally, convert the new intensity back to decibels:
New intensity level (in dB) = 10 * log10(new intensity) = 10 * log10(2 x 10^10) ≈ 103 dB
So, the new intensity level would be approximately 103 dB if the intensity were reduced by a factor of 5.

The work required to decrease the speed of the small truck from 21.0 m/s to 12.0 m/s on a level road is approximately 319,717.5 kg * m^2/s^2.

To calculate the work required to decrease the speed of the small truck, you need to know the change in kinetic energy. The formula for calculating work is:

Work = Change in Kinetic Energy

The change in kinetic energy can be calculated using the formula:

Change in Kinetic Energy = (1/2) * mass * (final velocity^2 - initial velocity^2)

Given:
Mass of the small truck = 2165 kg
Initial velocity = 21.0 m/s
Final velocity = 12.0 m/s

Let's calculate the change in kinetic energy:

Change in Kinetic Energy = (1/2) * 2165 kg * ((12.0 m/s)^2 - (21.0 m/s)^2)

Simplifying the equation:

Change in Kinetic Energy = (1/2) * 2165 kg * (144 m^2/s^2 - 441 m^2/s^2)

Change in Kinetic Energy = (1/2) * 2165 kg * (-297 m^2/s^2)

Change in Kinetic Energy = -319,717.5 kg * m^2/s^2

The negative sign indicates that work is done to decrease the speed.

Therefore, the work required to decrease the speed of the small truck from 21.0 m/s to 12.0 m/s on a level road is approximately 319,717.5 kg * m^2/s^2.
