What else can I help you with?
How does Vs speed vary with altitude?
As altitude increases, air density decreases. This reduction in air density leads to lower aerodynamic drag on an aircraft, allowing it to achieve a higher stall speed (Vs) at higher altitudes. Therefore, Vs increases with altitude due to the decrease in air density.
How aircraft speed and altitude can alter air pressure and how it complies with bernoulii's principle?
Aircraft speed and altitude cannot alter air pressure and how it complies with Bernoulli's principle. Aircraft speed decreases the pressure on the wings of the aircraft but this does not alter air pressure.
Why speed increases if its acceleration decreases?
stamina
What will happen to the average speed of an object if the distance increases but the time decreases?
If the distance increases but the time decreases, the average speed of the object would increase. This is because speed is calculated as distance divided by time, so when distance increases and time decreases, the ratio of distance to time increases, resulting in a higher average speed.
If the waves speed stays the same what decreases as the frequency increases?
The wavelength decreases.
Relationship of Vmc and stall speed?
(I'm sorry for editing this. The answer that was here couldn't have been more wrong. Short answer: Stall speed REMAINS THE SAME with the change of altitude but Vmc DECREASES with an increase in altitude. So at a higher altitude Vmc decreases and can be LOWER than Vs(stall speed) (AFH Figure 12-21) and adversely, as we descend, Vmc increases and can be higher than Vs at a lower altitude.

What form of energy is related to change in speed?
Kinetic energy is related to the change in speed of an object. As an object's speed increases, its kinetic energy also increases, and as its speed decreases, its kinetic energy decreases.
Why helicopter speed reduce as increase altitude?
Because as you increase altitude, the density of air decreases. To compensate for the decreased air density the rotor blades need a greater angle of attack, pushing the retreating blade closer to stall(reducing the maximum airspeed)
What happens to the speed of a wave if the frequency decreases and the waveleNgth increases?
If the frequency decreases and the wavelength increases, the speed of the wave remains constant. This is because the speed of a wave is determined by the medium it's traveling through, not by its frequency or wavelength.
Will the speed of an aeroplane be same which is flying at different altitudes and have same mach number 2?
no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
What increases when a wave period decreases.?
When a wave period decreases, speed increases.
Which statements below are true speed increases as time decreases for the same distance?
None of the statements are true. Speed is distance divided by time, therefore, as time decreases and distance remains constant, speed increases.
