The initial angular momentum of the propeller before the torque was applied will be 32 kg m²/s.

Torque is the force's twisting action about the axis of rotation. Torque is the term used to describe the instant of force. It is the rotational equivalent of force. Torque is a force that acts in a turn or twist.

The amount of torque is equal to force multiplied by the perpendicular distance between the point of application of force and the axis of rotation.

The given data in the problem is;

The rotational inertia is,I  = 2.0 kg m²

The clockwise torque is, T = 4.0Nm

The time period is,t= 4.0s,

The angular speed is,ω= 24 * (rad)/s

The initial angular momentum of the propeller is,I₀

The angular acceleration is found by the relation;

\(\rm \tau = I \times \alpha \\\\ \alpha =\frac{\tau}{i} \\\\ \alpha =\frac{4.0}{2.0} \\\\ \alpha= 2.0 \ rad/sec^2\)

The initial angular velocity is found as;

\(\rm \omega_f = \omega_0 + \alpha t \\\\ \omega_0 = \omega_f -\alpha t \\\\ \omega_0 =24 -[(-2.0)\times 4.0)] \\\\ \omega_0 = 16 \ rad/sec\)

The initial angular momentum of the propeller is found as;

\(\rm L_0 = I \omega_0 \\\\ L_0 = 20 \times (1.6) \\\\ I_0 = -32 \ kgm^2/s\)

Hence,the initial angular momentum will be 32 kg m²/s.

The induced current is zero when the loop is positioned in such a way that the top and bottom sides of the loop are parallel to the magnetic field lines. At these points, there is no change in magnetic flux through the loop, leading to zero induced EMF and current.

To determine the point(s) where the induced current is zero in a moving square loop, we need to consider the relationship between the motion of the loop and the direction of the magnetic field.

The induced current in a loop is caused by the change in magnetic flux through the loop. According to Faraday's law of electromagnetic induction, when the magnetic flux through a loop changes, an electromotive force (EMF) is induced, resulting in the flow of current.

Now, let's analyze the different cases and determine where the induced current is zero:

Top and bottom sides of the loop:

When the loop is positioned such that the top and bottom sides of the loop are parallel to the magnetic field lines, the magnetic flux through the loop remains constant as it moves. There is no change in flux, and therefore no induced EMF or current. The induced current is zero at these points.

Left and right sides of the loop:

When the loop is positioned such that the left and right sides of the loop are parallel to the magnetic field lines, the magnetic flux through the loop changes the most rapidly. This results in the highest induced EMF and current. The induced current is not zero at these points.

Percent saturation refers to the amount of hemoglobin in the blood that is bound to carbon monoxide (CO) compared to the total amount of hemoglobin that could be bound to CO. In the context of carbon monoxide poisoning, percent saturation is used to measure the severity of the poisoning. The higher the percent saturation, the more CO is bound to the hemoglobin, which reduces the amount of oxygen that can be transported by the blood, leading to oxygen deprivation in the body's tissues.

Explanation:

Answer:

When carbon monoxide enters the bloodstream, it combines with hemoglobin. The percent saturation of carbon monoxide poisoning is always 34%.

What happens to oxygen saturation in carbon monoxide poisoning?

Carbon monoxide causes cellular hypoxia by reducing oxygen carrying capacity and oxygen delivery to tissues, and it may also affect intracellular oxygen utilization.

What is the percentage of a carbon monoxide level?

Poisoning is considered to have occurred at carboxyhaemoglobin levels of over 10%, and severe poisoning is associated with levels over 20-25%, plus symptoms of severe cerebral or cardiac ischaemia.

The period of revolution in a binary-star system depends on the masses of the stars and the distance between them. In this case, we know that each star has a mass that is 2.4 times that of the Sun, and they are separated by a distance that is 4.2 times the distance between Earth and the Sun.

To calculate their period of revolution, we can use Kepler's third law, which states that the square of the period of revolution is proportional to the cube of the average distance between the stars, Therefore, the period of revolution for the two stars in this binary-star system is approximately 32.1 years, To find the period of revolution of a binary-star system, we can use Kepler's Third Law, which relates the period of revolution (T) to the semi-major axis (a) and the total mass of the system (M). The formula for Kepler's Third Law is:

T^2 = (4π^2 * a^3) / (G * M)

where:
- T is the period of revolution
- a is the semi-major axis (distance between the stars)
- G is the gravitational constant (6.67430 x 10^-11 m^3 kg^-1 s^-2)
- M is the total mass of the system

In this case, the mass of each star is 2.4 times the mass of the Sun (M_sun = 1.989 x 10^30 kg). Therefore, the total mass (M) is:

M = 2 * (2.4 * M_sun) = 4.8 * M_sun

The distance between the stars is 4.2 times the distance between Earth and the Sun (1 astronomical unit, AU = 1.496 x 10^11 m). Therefore, the semi-major axis (a) is:

a = 4.2 AU

Now, we can plug these values into Kepler's Third Law formula to find the period of revolution:

T^2 = (4π^2 * (4.2 AU)^3) / (G * 4.8 * M_sun)

First, convert AU to meters:

a (in meters) = 4.2 * 1.496 x 10^11 m ≈ 6.2832 x 10^11 m

Now, substitute the values:

T^2 = (4π^2 * (6.2832 x 10^11 m)^3) / (6.67430 x 10^-11 m^3 kg^-1 s^-2 * 4.8 * 1.989 x 10^30 kg)

After solving for T^2, we can find the period T by taking the square root of the result:

T = √(T^2) ≈ 22.64 years

So, the period of revolution for this binary-star system is approximately 22.64 years.

An inductance of approximately 0.0012 mH is needed with an 80 uF capacitor to construct an LC circuit that oscillates at a frequency of 60 Hz.

It's worth noting that the values of inductance and capacitance in an LC circuit can affect the oscillation frequency, and it may be necessary to adjust these values in order to achieve the desired frequency. Additionally, the actual oscillation frequency of an LC circuit may differ slightly from the calculated value due to various factors, such as resistance and the quality of the components.

To determine the inductance needed for an LC circuit to oscillate at a particular frequency, you can use the following formula:

Inductance (L) = 1 / (2 * π * f * C)

Where:

L is the inductance in henries (H)

pi is the mathematical constant pi (approx. 3.1416)
