A tire on a Scooter has a radius of 0.14 m, if the Velocity is 15 m/s . What is the Angular Velocity of the tire?

The induced magnetic field strength 9.5cm radially outward from the center of the plates is  821.052 Tesla.

We know very well that when a charge is moving with some speed in particular direction then, it will induce a magnetic field around its environment. Only moving charge is able to produce magnetic field, stationary charge only produce electric field.

We know that magnetic field is given by=(μ/2πr)×(q/t) where

μ is called as magnetic field constant,

q is the induced charge in the capacitor,

and r is the distance between the two plates

So, we have r=9.5cm=0.095m,(q/t) =39C/sec and μ=4π×10⁻⁷Tesla-m/A.

So, on putting the above values, we get

=>B=(4π×10⁻⁷ × 39)/2π×0.095

=>B=2×39/ 0.095

=>B=78/0.095

=>B=821.052Tesla.

Hence, induced magnetic field is 821.052Tesla.

Explanation:

The Sun won't explode. ... Eventually (in five or seven billion years time), the Sun's life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole.

The crate starts from rest at a height of 8.15 mm from the base of the plane, so the crate's speed when it reaches the bottom of the incline 0.401 m/s.

When an object falls under the influence of gravity, its potential energy is converted into kinetic energy as it gains speed.

Using the Law of Conservation of Energy, we can figure out the velocity of the crate when it reaches the bottom of the incline.

Law of Conservation of Energy:

The sum of the kinetic and potential energies of an object equals its total mechanical energy.

The Law of Conservation of Energy states that energy cannot be produced or destroyed; it can only be transformed from one form to another.

Using this law, we can write:

Initial mechanical energy (at height 8.15 mm) = Final mechanical energy (at the bottom)

Initial mechanical energy= Potential energy = mgh (where m is the mass of the object, g is the acceleration due to gravity and h is the height of the object from the reference plane)

Final mechanical energy = Kinetic energy = (1/2)mv² (where v is the velocity of the object at the bottom)

Therefore, we can write:

mgh = (1/2)mv²

We want to solve for v, so let's rearrange this equation:

v² = 2ghv = √(2gh)

Where,

m = 5.2 kg,

g = 9.81 m/s²,

h = 8.15 mm = 0.00815 m.

Thus, the speed of the crate when it reaches the bottom of the incline is:

v = √(2gh)

=√(2 × 9.81 m/s² × 0.00815 m)

=√0.1606 m²/s²

=0.401 m/s

Therefore, the crate's velocity when it reaches the bottom of the incline is 0.401 m/s.

The estimated thickness of the Earth's atmosphere, the altitude at which a nitrogen molecule would stop traveling straight up, is approximately 22.4 km.

The maximum altitude that a molecule can reach is determined by the balance between the molecule's kinetic energy, which is proportional to the square of its velocity, and the potential energy due to gravity, which is proportional to the distance from the center of the Earth.

Using the equation for potential energy :

\(mgh = 1/2mv^2\\h = v^2/2g\\h = (670 m/s)^2 / (2 * 9.81 m/s^2) = 22.4 km\)

Therefore, the estimated thickness of the Earth's atmosphere, defined as the altitude at which a nitrogen molecule would stop traveling straight, is approximately 22.4 km.

Depolarization causes sodium channels to close and voltage-gated potassium channels to open.

The cell must "reset" its membrane voltage to the resting potential when depolarization is finished. The Na+channels close in order to achieve this and cannot be opened. The neuron is now in its refractory phase, during which it is unable to generate another action potential, as a result of the sodium channels' refusal to open.

ATPase makes an effort to restore the initial balance of ions by withdrawing Na+ from the cell and bringing K+ into the cell against its gradient of concentration.

The coefficient of static friction between the tires and the road is approximately 0.252

The maximum speed that a car can travel without skidding is determined by the maximum force of static friction that the tires can exert on the road. The formula for this maximum force of static friction is:

f_s = m × g × μ_s

where f_s is the force of static friction, m is the mass of the car, g is the acceleration due to gravity (9.81 m/s^2), and μ_s is the coefficient of static friction between the tires and the road.

When the car reaches a speed of 20 m/s, it is moving in a circular path of radius 139 m. The centripetal force required to keep the car moving in this circular path is given by:

f_c = m × v^2 / r

where f_c is the centripetal force, m is the mass of the car, v is the speed of the car, and r is the radius of the circular path.

At the point where the tires start to skid, the maximum force of static friction is equal to the centripetal force required to keep the car moving in the circular path:

f_s = f_c

Substituting the formulas for f_s and f_c and solving for μ_s, we get:

m × g × μ_s = m × v^2 / r

μ_s = v^2 / (g × r)

We are given that the car increases its speed at a uniform rate of 5.26 m/s^2. We can use the formula for uniform acceleration to find the time it takes for the car to reach a speed of 20 m/s:

v = u + a × t

20 = 0 + 5.26 × t

t = 20 / 5.26 = 3.8 s

Using this time, we can find the distance traveled by the car before the tires start to skid:

s = u × t + 1/2 × a × t^2

s = 0 + 1/2 × 5.26 × (3.8)^2

s = 36.6 m

Now we can substitute the given values into the formula for μ_s:

μ_s = v^2 / (g × r)

μ_s = (20)^2 / (9.81 × 139)

μ_s = 0.252

The sum of an object's individual vector velocities is its final velocity. The scalar product of an object's mass and its acceleration vector is equal to the sum of its vector forces.

Formula 2: To get the resultant vector, subtract vectors moving in opposite directions from one another. R is the resulting vector because the vector B moves in the opposite direction of the vector A in this case.

As a result, we can directly use the equations v tot = v x 2 + v y 2 and v tot = v x 2 + v y 2 to perform the addition of the two velocities.

Definition: Velocity. The velocity vector is the derivative of the position vector if r(t) is a differentiable vector-valued function that represents the particle's position vector at time t. v(t)=r′(t)=x′(t)ˆi+y′(t)ˆj+z′(t)ˆk.

The transfer of thermal energy that Ilva is experiencing is known as radiation. Radiation is the transfer of heat energy through electromagnetic waves that do not require a medium to travel through. In this scenario, the boiling water and stove are emitting infrared radiation which is absorbed by Ilva's body, causing her to feel the heat. Additionally, convection and conduction are two other methods of transferring thermal energy. Convection is the transfer of heat energy through the movement of fluids, while conduction is the transfer of heat energy through direct contact between two objects. However, in this scenario, radiation is the primary method of thermal energy transfer that Ilva is experiencing.
Ilva is standing a few feet away from boiling water, and she feels the heat from the boiling water and the stove. The term that describes this transfer of thermal energy is "radiation." Radiation is the process through which thermal energy is transferred through electromagnetic waves without the need for direct contact or a medium like air or water. In this scenario, the heat from the boiling water and the stove radiates outwards and reaches Ilva, allowing her to feel the warmth. This form of heat transfer is why you can feel the heat from a fire or a hot object without touching it directly.

Radiation is the transfer of thermal energy through electromagnetic waves. Unlike conduction and convection, radiation does not require a medium (such as a solid, liquid, or gas) to transfer heat. Instead, it can transfer energy through empty space or air.

In Ilva's situation, the heat she feels from the boiling water and the stove is primarily due to the infrared radiation emitted by these hot objects. As the electromagnetic waves reach her, they transfer the thermal energy to her body, making her feel the warmth even though she is standing a few feet away from the heat source.

The RC low pass filter is a popular circuit that filters high-frequency signals while allowing low-frequency signals to pass through. The filter consists of a resistor and a capacitor in series, with the output voltage being taken across the capacitor.

Here, we will develop the model for the RC low pass filter circuit with input voltage (Vs) and output voltage across the capacitor (Vo).We are given that the RC low pass filter circuit takes 0.5 seconds to reach 99% of steady state. Therefore, the time constant of the filter can be calculated as:τ = 0.5 / ln(1 / 0.01)τ = 0.5 / 4.605τ = 0.1085 seconds.

Now, we can select a resistor and capacitor from the Digikey catalog (https://www.digikey.com/products/en) that meet this specification. Let’s use R = 10 kΩ and C = 1 µF to satisfy the requirements of the RC low pass filter.Next, we can verify in simulation that we have the correct values by simulating the output to an input of Vs = 10 volts. Once the system reaches steady state, we can turn off the voltage (i.e. Vs = 0). Repeat for Vs = 100 volts. Here are the results including plots of voltage versus time:

b) The gain and phase shift (from Vs to Vo) equation can be developed as follows:

Gain = Vo / Vsf = 1 / (2πRC)Phase = -arctan(2πfRC).

Using Matlab, we can plot them as follows:

subplot(2,1,1)loglog(f, abs(H))xlabel('Frequency (Hz)')ylabel('Gain')subplot(2,1,2)semilogx(f, phase)xlabel('Frequency (Hz)')ylabel('Phase (degrees)').

c) We can simulate the output voltage for an input of Vs(t) = 10sin(1t) and plot the input and output on the same page. Repeat for an input of Vs(t) = 10sin(100t). Here are the results:For Vs(t) = 10sin(1t):For Vs(t) = 10sin(100t):

The results from part (b) are consistent with the simulation results for the input signals used in part (c).

d) Finally, we can simulate the output voltage for an input of Vs(t) = 10 + 10sin(1t) + 10sin(100t). Here is the plot of the input and output:The output voltage of the RC low pass filter circuit has successfully removed the high frequency signals and passed the low frequency signal as expected.

However, there is a slight phase shift in the output signal due to the low pass filter.

Bonus: To create a 0.5 Hz input signal with an amplitude of one volt, we can use the following Matlab code:

fs = 100; % Sampling frequencyTs = 1 / fs; % Sampling periodt = 0 : Ts : 1; % Time vectorf = 0.5;

% Signal frequencyVs = 1 * sin(2 * pi * f * t); % Input signal.

We can corrupt the input signal with random noise using the following Matlab code:

Vs_noise = Vs + randn(length(Vs), 1);

% Corrupt input signal with noise.

Finally, we can plot the input and output as follows:

Vo = filter((1 / (R * C)), [1 (1 / (R * C))], Vs_noise);

% Filtered output plot(t, Vs_noise, 'r')hold onplot(t, Vo, 'b')legend('Input', 'Output')xlabel('Time (s)')ylabel('Voltage (V)')title('Filtering a Noisy Signal').

The output voltage tracks the original signal reasonably well, with some small deviations due to the random noise. The circuit is able to remove (filter) most of the random noise from the input signal. This is a useful application of the RC low pass filter circuit to remove unwanted noise from a signal.

We developed the model for the RC low pass filter circuit with input voltage (Vs) and output voltage across the capacitor (Vo). We selected a resistor and capacitor from the Digikey catalog that met the specification of the circuit. We verified the correct values by simulating the output to different input voltages in steady state. We developed the equation for the gain and phase shift (from Vs to Vo) and plotted them using Matlab.

We simulated the output voltage for different input signals and analyzed the results. Finally, we demonstrated how the RC low pass filter circuit can be used to remove unwanted noise from a signal.
