An airplane is headed due south with an airspeed of 300 kph. A wind is blowing from the west at 120 kph. What is the ground speed and direction of the plane?.
The ground speed and direction of the plane is 323 kph with a directional bearing of S 22° E.
What is speed?
The rate at which an object moves along a path is defined as its speed. The SI Unit of speed is metre per second or m/s or m.s-1.
What is vector?
A vector is a quantity that has magnitude as well as direction. It is often represented by an arrow whose length is proportional to the quantity and whose direction is the same as that of the quantity. Resultant vector is the sum of two or more vectors.
Since the airplane is headed due south with an airspeed of 300 kph, its vector is V = (-300 kph) j.
Also, the wind is blowing from the west at 120 kph. Its vector is v = (-120 kph) i.
So, the ground speed of the plane V' is the resultant vector of the airspeed and wind speed.
[tex]So, V' = v + V[/tex]
[tex]V' = (-120 kph)i + (-300 kph)j[/tex]
So, its magnitude V' = √[tex]x^{2} + y^{2}[/tex] where,
[tex]x = -120 kphy = -300 kph.[/tex]
[tex]So, V' =[/tex] √ [tex][(-120 kph)^{2} + (-300 kph)^{2}][/tex]
= √[tex](104400 kph^{2} )[/tex]
[tex]= 323.11 kph[/tex]
≅ 323 kph
The direction of plane,
Ф[tex]Its direction, Ф = tan^{-1} (y/x)\\Ф\\ = tan^{-1}(-300 kph/-120 kph)\\Ф\\ = tan^{-1}(2.5)\\Ф\\ = 68.2°[/tex]
From south line, α = [tex]90 - 68.2[/tex] ≅ 22°
So, the direction of the plane is S22°E.
The ground speed and direction of the plane is 323 kph with a directional bearing of S 22° E.

The force that prevents motion when the surfaces of two objects come into contact is known as friction. Friction lessens a machine's mechanical advantage, or, to put it another way, friction decreases the output to input ratio. A car spends one-fourth of its energy-reducing friction. However, friction in the clutch and the tyres also contribute to the vehicle's ability to maintain its position on the road. One of the most important phenomena in the physical universe is friction, which affects everything from machines to molecular structures to matches. Let's talk about frictional force and its various forms in this article.The formula to calculate the static friction is given as Static Friction = Normal Force x Static Friction coefficient

Now compare the distance from the first dark fringe above the middle of the screen (where the intensity is nearly zero) to each of the two slits. How do the distances compare? 500 nm 11310 Light Generator The difference in the distances is equal to a quarter of the wavelength of the wave. The distances are the same The difference in the distances is equal to half the wavelength of the wave, The difference in the distances is equal to the wavelength of the wave.
the distance from the first dark fringe above the middle of the screen o each of the two slit is compared by option c difference in the distance is equal to the half the wavelength of the wave
To obtain the first dark fringe, the light from both slits is phase shifted by pi angle. As a result, the path difference between the two slits is the difference in the distance is equal to the half the wavelength of the wave The interferences that cause the dark fringe formation are destructive in nature. The interference fringes are denoted as destructive in the resultant amplitude, and their intensity is equal to zero.

identfy the objective of this lab group of answer choices to find the speed of sound in water to find the resonance in air column to find the wavelength of a sound wave to determine the speed of sound waves in the air
The objective of this lab is to find the resonance in air column.
The apparatus of this experiment are a long cylindrical plastic tube attached to a water reservoir. The length of the water column can be changed by raising or lowering the water level while the tuning fork is held over the open end of the tube.
Resonance is indicated by a sudden increase in the intensity of the sound when the column is adjusted to a proper length.
The resonance is nothing but a standing wave phenomenon in the air column and occurs when the column length is λ/4, 3λ/4, 5λ/4.
Second resonance is occurred at third harmonic and third resonance is occurred at fifth harmonic.
