What is a frictional force ?

The force produced when two surfaces slide past one another and make contact is known as frictional force. The surface texture of these forces and the amount of force pressing them together have the biggest impact.

Mass of the person

m1 = 93kg

Mass of the air plane

m2 = 118000 kg

Coefficient of static friction between the shoes of the person and floor

μs=0.79

Acceleration due to gravity

g=9.8m/s^2

The maximum force the person can apply on the floor is equal to his weight

F = w = m1∗g

         = 93∗9.8=911.4 N

The maximum frictional force he can get from the floor is the product of coefficient of static friction and normal reaction

Ff = μs∗N

   = μs∗W

   = 0.79 ∗ 911.4 = 720 N

Let's assume that the individual is able to use or apply the entire frictional force in pushing the airplane.

Following that, the relationship can be used to determine the acceleration an air plane created.

Ff = m2 * a

The lowest frequency of a periodic waveform is known as the fundamental frequency, also known as just the fundamental. The musical pitch of a note that is heard as the lowest partial existent in music is referred to as the fundamental. The fundamental frequency, or frequency of the difference between adjacent frequencies, in terms of a superposition of sinusoids is the lowest frequency sinusoidal in the total of harmonically linked frequencies. The fundamental, which denotes the lowest frequency counting from zero, is sometimes shortened as f₀. It is more typical to shorten it to f1, the first harmonic, in other instances. The zeroth harmonic in this situation would be 0 Hz.

The light emitted by hydrogen atoms appears red because the most intense line in its spectrum, at 656 nm, is in the red section of the visible spectrum.

The principal quantum number(n) for the Lyman series is 1. As a result, the Lyman series has the highest energy in the hydrogen spectrum. This is due to the fact that helium has more electrons than hydrogen. Helium has two, while hydrogen has only one. More spectral lines will be noticed as more electrons are stimulated. Helium therefore has more spectral lines than hydrogen. Gamma rays are the most energetic, have the shortest wavelengths, and have the highest frequencies.

When a moving pool ball hits a stationary ball, some kinetic energy from the moving pool ball is transferred to the stationary ball and it attains momentum.

Both in the case of elastic and inelastic collisions, momentum is preserved. That means the total momentum will always be the same.

Momentum (ρ) is defined as "mass in motion". There are two factors affecting the momentum. Mass(m) and velocity(v).

                       ρ = m×v

So for a stationary object momentum will be 0. When the moving ball hits the stationary ball, it starts moving, because it gets kinetic energy from the moving ball. The total momentum before and after the collision will always be equal.

               mₐ₁× vₐ₁ = mₐ₂×vₐ₂ + m₂ v₂

                     mₐ₁× vₐ₁ is the momentum of ball A before the collision

                     mₐ₂×vₐ₂ is the momentum of ball A after collision

                     m₂ v₂    is the momentum of ball B after  collision.

So the stationary ball begins to move after the collision due to increased kinetic energy and attains some momentum. The total momentum of the system remains the same.

Capacitance is an electrical property of a material or system that is related to the amount of charge it can store in an electric field. It is measured in Farads (F), which is the ratio of the electric charge stored on a capacitor to the applied voltage. In other words, it is an expression of the ability of an electrical system or component to store energy in the form of an electric field. It is an important factor in the design of electrical systems, and can be used to control the flow of electric current in circuits. It is also used to measure the amount of voltage that a capacitor can sustain before its capacitance decreases.

A 3 wavelength lamp is a type of light therapy device used to improve skin health and appearance.

Wavelength is the distance between two successive peaks or troughs of a wave, such as light, sound, or other forms of energy. It is measured in meters or nanometers and is related to the frequency of the wave, as the frequency is inversely proportional to the wavelength. Wavelength can also be used to describe the physical size of an object, such as a particle or cell.

It emits both visible and invisible light in three different wavelengths, namely red, blue and near-infrared. The red wavelength helps to reduce inflammation and improve circulation, while the blue wavelength helps to kill acne-causing bacteria. The near-infrared wavelength helps to boost collagen and elastin production, which can help to improve skin texture and firmness.

1). The structure labeled "B" is: Axon branches

-Because a motor neuron's axon has multiple branches that come together to form a neuromuscular junction, one of its axons can innervate numerous muscle fibers.

- These branches carry potential action in the direction of certain synaptic knobs.

2). The structure labeled "A" is: Axon terminals

-It creates a neuromuscular connection with the motor end plate of the sarcolemma and features a bulged structure at its most terminal end.

- Neurotransmitter is exocytosed from the axon terminal.

- Synaptic cleft is the area between the sarcolemma and the synaptic knob at the axon terminal.

Any of the button-like ends of axons through which axons create synaptic connections with other nerve cells or with effector cells is known as an axon terminal. Neurotransmitter-containing synaptic vesicles bind at the axon terminal. The cell opens up to calcium ions upon activation by a graded potential or by an action potential of the presynaptic neuron. This starts a chain reaction that leads to the synaptic vesicles fusing into the axon terminal membrane. The synaptic vesicle proteins that the calcium ions activate create fusion holes that allow the neurotransmitters to leave. The effects of the neurotransmitters on the target cell only last for a brief period of time.

The equivalent capacitance is  21 μF.

In electrical engineering, equivalent capacitance often abbreviated as C eq—is a measurement of the total combined electric charge held in two or more capacitors connected in series or parallel. A capacitor is an electrical device that stores electrical energy into the electric field. Typically, a capacitor has two electrical leads that are separated by a dielectric or other insulating substance.

We are given that,

capacitance =c₁ =9  μF

capacitance = c₂ =6  μF

capacitance = c₃ = 3  μF

capacitance = c₄ =2  μF

capacitance = c₅ = 1  μF

Thus If the capacitor is connected in parallel the equivalent capacitance, cₐ can be calculated by the equation,

Part(a) The equation for the loop is 0 −1−(R1 +R2)I2+(R3+R2)I3=0

Part(b) The current through the bottom branch 13 is 0.75 A.

(a) This equation is found by applying the loop rule, which states that the sum of voltage drops around a loop is equal to zero. To find the equation, we start at the point, and move clockwise around the loop. At each point, we add the voltage drop of the component connected between that point and the previous point. We then substitute the component values into the equation.

For example, the voltage drop across R1 is equal to I2 * R1. In this equation, I2 and I3 are the currents through R2 and R3 respectively.

(b) To calculate this, we need to use Ohm's Law, which states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance.

First, we need to calculate the total resistance of the circuit.

       R total = R_1 + (1/2)*R_2 + R_3

                    = 0.5 + (1/2)*2.5 + 0.5

                    = 2.5 Ω

Now, we can use Ohm's Law to calculate the current through the bottom branch.

             I 13 = V/R

                     = (12-0.5)/2.5

                     = 0.75 A

Therefore, the current through the bottom branch 13 is 0.75 A.

Answer:

Driver 1

Explanation:

In this scenario, driver 1 has a greater average speed than driver 2. To determine the average speed of a driver, we need to divide the distance traveled by the time it took to travel that distance. In the case of driver 1, who traveled 100 km in 2 hours, their average speed would be 100 km / 2 hours = 50 km/hour. For driver 2, who traveled 100 km in 3 hours but stopped for an hour halfway, their average speed would be 100 km / (3 hours - 1 hour) = 33.33 km/hour. Since 50 km/hour is greater than 33.33 km/hour, driver 1 has a greater average speed.
