Explanation:

Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... Newton's second law is one of the most important in all of physics.

The pressure will be 41.9 kPa when the temperature rises to 475 degrees Celsius.

First, we need to convert the initial temperature from Celsius to Kelvin by adding 273.15, so the initial temperature is 296.15 K. Then, we can solve for nR/P to find a constant value.

(nR/P)_1 = (296.15 K * 111 kPa) / (1 mol)

Next, we can use this constant value to solve for the new pressure at 475 degrees Celsius (748.15 K).

P_2 = (nR / (748.15 K)) * (1 mol / (nR/P)_1)

Plugging in the values, we get:

P_2 = (296.15 K * 111 kPa / 1 mol) * (1 mol / (748.15 K)) = 41.9 kPa

Answer:

Resultant velocity = 3.11 m/s.

Explanation:

It is given that,

The velocity of a boat is 2.778 m/s due North

The velocuity of river is 1.389 m/s due east.

We need to find the resultant velocity. The angle between these two velocities is 90 degrees. The resultant is given by :

\(v=\sqrt{v_b^2+v_r^2} \\\\v=\sqrt{2.778 ^2+1.389 ^2} \\\\v=3.11\ m/s\)

So, the correct option is (a).

The second-order minimum thickness of the film required is 1.41 μm.

The minimum thickness required for a thin film to reflect a given color is half the wavelength of the light in the film material. For a second-order minimum thickness, the formula is given by;

t2=2nλwhere t2 represents the second-order minimum thickness of the film, n is the refractive index of the film material, and λ is the wavelength of the light in air.

If the wavelength of the light in air is 470 nm, then the second-order minimum thickness of the film required is given by;t2=2nλ= 2 × 1.5 × 470 nm = 1410 nm = 1.41 μm.

The second-order minimum thickness of the film required is 1.41 μm.

The elements of funk style that made it well-suited for nuclear fusion with contemporary jazz were its strong emphasis on rhythm, use of syncopation, and incorporation of improvisation.

Funk music is characterized by its rhythmic groove, often built around a repetitive bass line and syncopated rhythms. This emphasis on rhythm and groove is also a defining feature of contemporary jazz, which frequently incorporates elements of funk into its compositions. Additionally, both funk and jazz place a strong emphasis on improvisation, allowing musicians to explore and experiment with different musical ideas in real time.

However, there is one element of funk style that may have made it less well-suited for fusion with contemporary jazz: its often simplistic harmonic structures. While funk music relies heavily on rhythm and groove, it generally does not use complex chord progressions or harmonic variations. In contrast, contemporary jazz often features more complex harmonic structures, with frequent modulations and chord substitutions. This difference in harmonic complexity may have made it more challenging for funk musicians to seamlessly integrate with contemporary jazz ensembles.

The volume of the metal cube is 2.8 mL or 2.8 cm³.

The volume of the metal cube can be calculated by subtracting the initial volume of water in the cylinder from the final volume of water when the cube is added.

Final volume - Initial volume = Volume of cube

20.3 mL - 17.5 mL = 2.8 mL

Therefore, the volume of the metal cube is 2.8 mL.

To convert the volume of the cube from mL to cm³, we can use the fact that 1 mL is equal to 1 cm³.

Explanation:

The net electric force on the charge is located at the lower right-hand corner of the triangle is \(Fr = \sqrt{3} \times\dfrac{q^2}{4 \times \pi \times 0 \times a^2 }\).

Electric force is the attraction or repulsive interaction between any two charged things. Similar to any force, Newton's laws of motion describe how it affects the target body and how it does so. One of the many forces that affect objects is the electric force.

The given electrostatic force is:

F = k  x Q1 x Q2 / R²

here, Q1 & Q2 = charges

R = distance between charges

The force between q and q

F1 = k x q x q / a² = F

The force between q and '-2q'

F2 = k x q x 2 x q / a²  = 2 x F (towards '-2q' charge)

From the diagram given below, angle between F1 & F2 = A = 120°

So, the resultant force will be:

\(Fr = \sqrt(F1^2 + F2^2 + 2 \times F1 \times F2 \times cosA)\\Fr = \sqrt(F^2 + (2 \times F)^2 + 2 \timesF \times2 \timesF \timescos(120)\\Fr = \sqrt(5 \times F^2 - 2 \timesF^2)\\Fr = F \times \sqrt(3)\)

Therefore, the net electric force on the charge is located at the lower right-hand corner of the triangle is \(Fr = \sqrt{3} \times\dfrac{q^2}{4 \times \pi \times 0 \times a^2 }\).

The question is incomplete. Your most probably complete question is given below:

The image of the triangle is attached below:

In clockwise direction the propellers rotate as seen from the rear of the plane. If the plane is flying horizontally and suddenly pulls upward, the nose of the plane would veer upward. The correct options are B and A respectively.

The propellers rotate anticlockwise when viewed from the back of the aircraft.

When observed from the rear, an anticlockwise rotation direction corresponds to propellers spinning in the forward direction because the angular momentum of the propellers points directly forward from the plane.

The nose of a plane tends to pull forward when a plane flying horizontally suddenly pulls upward. This is brought on by the direction of the lift force produced by the wings changing.

By raising the nose, the angle of attack widens, increasing the lift force that raises the plane's nose upward. The change in the aerodynamic forces exerted on the aircraft is what causes the nose to rise upward.

Thus, the correct options are B and A respectively.

The traveler's weight on another planet whose radius is 3 times that of Earth and whose mass is 2 times that of Earth is 21.647 N

The following is the solution to the given problem:

Mass and gravity are related to one another. Gravity is generated by the planet's mass, and the magnitude of the gravitational force is determined by the mass of the planet on which the object is situated, as well as the mass of the object.

Mass, distance, and gravity are all factors that influence the gravitational force. Mass is directly proportional to the gravitational force and inversely proportional to the square of the distance from the gravitational force's center.

Here is the formula: Force of gravity = G(M1M2)/d²where, G is the gravitational constant 6.67 x 10^{-11} N(m/kg)^2, M1 is the mass of the first body, M2 is the mass of the second body, d is the distance between the centers of two bodies.

On earth, the traveler weighs 682 N. On another planet whose radius is 3 times that of Earth and whose mass is 2 times that of Earth, we have to calculate the traveler's weight.

Mass of Earth is 5.972 × 10^24 kg2,

Radius of Earth is 6.371 x 10^63.

The mass of the planet whose radius is 3 times that of Earth and whose mass is 2 times that of Earth.

Mass of the planet = 2 x mass of Earth = 2 x 5.972 × 10^24 kg = 1.1944 × 10^25 kg4.

The radius of the planet whose radius is 3 times that of Earth,

Radius of the planet = 3 x radius of Earth = 3 x 6.371 x 10^6 m = 1.9113 × 10^7 m5.

The distance between the two planets.

Distance between two planets = radius of planet + radius of Earth

= 1.9113 × 10^7 m + 6.371 x 10^6 m

= 2.54813 x 10^7 m

= 2.54813 x 10^10 cm.

Putting all the values in the formula.

Force of gravity = G (M1 M2) / d²

Where, Mass of the traveler on the other planet is m.

Mass of the Earth is M1 = 5.972 × 10^24 kg.

Mass of the other planet is M2 = 2 x 5.972 × 10^24 kg = 1.1944 × 10^25 kg.

Radius of the Earth is r1 = 6.371 x 10^6 m.

Radius of the other planet is r2 = 3 x 6.371 x 10^6 m = 1.9113 × 10^7 m.

Distance between the two planets is d = 2.54813 x 10^10 cm.682

= G (M1 M2)/d²

G = 6.674 × 10^-11 N m² / kg²

Force of gravity on other planet = G(mM2)/r² where m is the mass of the traveler on the other planet

= 6.674 × 10^-11 × (m × 1.1944 × 10^25)/(1.9113 × 10^7)²

Weight on another planet = force of gravity on another planet × mass of the traveler on another planet

= (6.674 × 10^-11 × (m × 1.1944 × 10^25)/(1.9113 × 10^7)²) × m

= 21.647 N (approximately)

Therefore, the traveler's weight on another planet whose radius is 3 times that of Earth and whose mass is 2 times that of Earth is 21.647 N (approximately).
