Answer:

Its resultant velocity will be 320 km/h.

Explanation:

The tail wind is called the wind that brings greater speed to an airplane, because it has the same direction as the airplane and, therefore, contributes a positive force to the force that the airplane's engines print on it.

Thus, a tailwind adds its speed to the speed of the plane, developing a resulting speed higher than that marked on the air transport speedometer.

In the case, given that the speed of the plane is 240 km / h and the tail wind is 80 km / h, the resulting speed will be 320 km / h.

The charge on the 6 μF capacitor is 10.29 μC.

What is the charge of capacitor?

The charge of a capacitor is the amount of electric charge stored on its plates due to the potential difference (voltage) between them. The charge is directly proportional to the capacitance and the voltage across the capacitor, according to the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage.

First, we can calculate the equivalent capacitance of the two capacitors connected in parallel:

\(C_{parallel}\)= C1 + C2 = 6 μF + 8 μF = 14 μF

Next, we can calculate the total equivalent capacitance of the circuit, which is the capacitance of the parallel combination in series with the 14 μF capacitor:

1/\(C_{total}\) = 1/ \(C_{parallel}\) + 1/C3

1/\(C_{total}\) = 1/14 μF + 1/14 μF

1/\(C_{total}\) = 1/7 μF

\(C_{total}\) = 7 μF

Using the formula Q = CV, we can calculate the charge on the 6 μF capacitor:

Q = C × V = 6 μF × 12 V / 7 μF = 10.29 μC

Therefore, the charge on the 6 μF capacitor is 10.29 μC.

What is capacitance?

Capacitance is the ability of a capacitor to store electric charge when a voltage is applied across its terminals. It is defined as the ratio of the electric charge stored in the capacitor to the voltage applied to it, and its unit is the farad (F). A capacitor with a high capacitance value can store more charge for a given voltage than a capacitor with a lower capacitance value.

For component C, a filament lamp, the current-voltage characteristic would be a curve that is not linear. It would exhibit a non-linear increase in current with increasing voltage. At lower voltages, the lamp would have low resistance, but as the voltage increases, the resistance of the filament also increases due to the phenomenon of thermal self-regulation. This leads to a slower increase in current at higher voltages.

For component D, a component that does not obey Ohm's law, the current-voltage characteristic could be any non-linear curve depending on the specific component chosen. Examples of components that do not obey Ohm's law include diodes and transistors.

b. The shape of the characteristic for component C, the filament lamp, can be explained by its construction. A filament lamp consists of a filament made of a resistive material, typically tungsten, which heats up and emits light when an electric current passes through it. As the voltage across the filament increases, the temperature of the filament increases as well, causing its resistance to increase. This increase in resistance results in a slower increase in current with increasing voltage, leading to the characteristic non-linear curve observed.

c. The component chosen for D, which does not obey Ohm's law, could be a diode. A diode is a two-terminal electronic component that allows the current to flow in only one direction. It exhibits a non-linear current-voltage characteristic where it conducts current only when the voltage is above a certain threshold, known as the forward voltage. Below this threshold, the diode has a high resistance and blocks current flow in the reverse direction. The characteristic curve of a diode would show negligible current flow until the forward voltage is reached, after which it exhibits a rapid increase in current with a relatively constant voltage.

force = 360 N

spring constant k = ?

formula : F = kx

k = F/ x

k = 360 ÷ 4.7011

k= 76.578 Nm^-1

The spring constant of the wire of a steel wire 4.7 m long stretches 0.11 cm when it is subjected to a tension of 360 N is 76.57 N/m.

Simple, symmetrical motion i.e., SHM is a genuinely fascinating kind of agitation. It is continuously used in the objects' oscillatory motion. Most springs have SHM. The "spring constants" that are intrinsic to springs determine how stiff they are. A well-known law, Hooke's law, describes the SHM and provides a formula for the applied force using the spring constant.

Simple harmonic motions and Hooke's law are related to the definition of the spring constant. Therefore, we must first examine Hooke's rule before attempting to define the spring constant and comprehend how it operates.

Given:

The tension force, T = 360 N,

The length of the wire, L = 4.7 meters,

The elongation, l = 0.11 cm,

Calculate the spring constant by the following formula,

k = T / l

( l = x(0.11 /100) m + 4.7 m= 4.7011 m)

Here, k is the spring constant.

Substitute the values,

k = 360 / 4.7011

k = 76.57 N / m

Therefore, the spring constant of the wire of a steel wire 4.7 m long stretches 0.11 cm when it is subjected to a tension of 360 N is 76.57 N/m.

The rms voltage measured across the secondary coil is 565.68 V.

The root mean square (RMS) value of an alternating current (AC) or voltage is the equivalent steady direct current (DC) value that produces the same heating effect or power dissipation in a resistor. In other words, it is the DC voltage or current that would produce the same amount of heat as the AC voltage or current over a given time period.

The rms voltage (V_rms) across the secondary coil can be calculated using the formula:

V_rms,secondary = (N_secondary/N_primary) * V_rms,primary

where N_secondary is the number of turns in the secondary coil, N_primary is the number of turns in the primary coil, and V_rms,primary is the rms voltage across the primary coil.

The rms voltage across the primary coil can be found from the given voltage function:

V_rms,primary = (1/√2) * V_peak,primary

where V_peak,primary = 200 V is the peak voltage across the primary coil.

Substituting the values, we get:

V_rms,primary = (1/√2) * 200 V = 141.42 V

Now, using the formula above, we can calculate the rms voltage across the secondary coil:

V_rms,secondary = (700/175) * 141.42 V = 565.68 V

Therefore, the rms voltage measured across the secondary coil is 565.68 V.

Mark's work decreases when he climbs the same flight of stairs again in the same amount of time without the cello.

The correct answer is option D.

The amount of work Mark does depends on the weight of the cello, as well as the distance he climbs and the time it takes. Work is calculated using the formula :

Work = Force × Distance.
In the given scenario, Mark is carrying a full-sized cello while climbing the stairs. The weight of the cello adds to the force he exerts. So, the total force Mark exerts is the weight of the cello plus his own weight (375 N).

When Mark climbs the stairs with the cello, he is doing work against the force of gravity.

The work done is equal to the force exerted multiplied by the distance climbed (375 N + weight of cello) × 4 m.

Now, if Mark were to climb the same flight of stairs again in the same amount of time (3 seconds), but this time without the cello, the amount of work he does would decrease. This is because without the cello, the force exerted would only be Mark's weight (375 N), which is less than the total force exerted with the cello.

Therefore, mark's work decreases.

The weight of 15N should be hung at a distance of 4/3 units from the fulcrum, on the opposite side of the bar to a weight of 20N.

The fulcrum is attained equilibrium when the principle of moments is equal to zero. The principle of momentum is defined as the body is said to be balanced when the clockwise movement about the point is equal to the anticlockwise movement about the same point.

When a weight of 15N is hung on the bar, it produces an anticlockwise movement with the same magnitude, opposes the clockwise moment produced by the weight of 20N on the fulcrum.

To find the distance (d) at which the 15N weight should be hung, the distance from the 20N weight to the fulcrum is 1 unit.

Louis Armstrong's average velocity in the time trial was approximately 1.078 km/min.

To calculate the average velocity, divide the total displacement by the total time taken. In this case, Louis Armstrong rode his bike 55 km to the east in a time trial lasting 51 minutes.

Average Velocity = Displacement / Time

Displacement = 55 km (since he rode 55 km to the east)

Time = 51 minutes

Average Velocity = 55 km / 51 min

To express the average velocity in km/min, convert the time from minutes to minutes.

1 hour = 60 minutes

Average Velocity = 55 km / 51 min × (1 hour / 60 min)

Average Velocity = 55 km / 51 min × (1/60) hour

Rolling Cylinder Kinetic Energy.

A cylindrical solid object of mass 400g and radius of 20cm is rolling down as inclined plane at speed of 3m/s. calculate the kinetic energy of the given object.​

To calculate the kinetic energy of a rolling cylinder, we need to use the formula for rotational kinetic energy, which is:

K_rotational = (1/2) * I * ω^2

where I is the moment of inertia and ω is the angular velocity.

For a cylinder rolling without slipping down an inclined plane, the total kinetic energy is the sum of translational kinetic energy and rotational kinetic energy, which is:

K_total = K_translational + K_rotational

where K_translational is given by:

K_translational = (1/2) * m * v^2

where m is the mass of the cylinder, and v is its linear velocity.

First, let's find the moment of inertia of the cylinder. For a solid cylinder, the moment of inertia is given by:

I = (1/2) * m * r^2

where r is the radius of the cylinder. Substituting the given values, we get:

I = (1/2) * 0.4 kg * (0.2 m)^2 = 0.008 kg·m^2

Next, let's find the linear velocity of the cylinder. The speed of the cylinder is given as 3 m/s, so the linear velocity is:

v = 3 m/s

Now we can calculate the translational kinetic energy:

K_translational = (1/2) * m * v^2 = (1/2) * 0.4 kg * (3 m/s)^2 = 0.9 J

Finally, we can calculate the rotational kinetic energy:

K_rotational = (1/2) * I * ω^2

Since the cylinder is rolling without slipping, the linear velocity is related to the angular velocity as:

v = ω * r

Rearranging this equation, we get:

ω = v / r = 3 m/s / 0.2 m = 15 rad/s

Substituting the values, we get:

K_rotational = (1/2) * 0.008 kg·m^2 * (15 rad/s)^2 = 1.8 J

Therefore, the total kinetic energy of the cylinder is:

K_total = K_translational + K_rotational = 0.9 J + 1.8 J = 2.7 J

Therefore, the kinetic energy of the given object is 2.7 Joules.
