Mazyrski [523]

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will Increase and true altitude will increase.

<h3>What is Altitude?</h3>

This refers to the vertical elevation of  a body and is the measurement of the height above the sea or ground level. An airplane's altitude is directly proportional to the airspeed as long as the power is constant.

This means that increase in airspeed will lead to an increase in altitude and vie versa. This is the reason why as it runs fast, it can be observed that it begins to elevate.

an image of a statue appears to be 11.5cm behind convex mirror with focal length 13.5cm. Find the distance from the statue to th
professor190 [17]

Answer:

77.625 cm

Explanation:

The given distance of the image behind the convex mirror, v = 11.5 cm

The focal length of the mirror, f = 13.5 cm

The mirror formula for convex mirror is given as follows;

\dfrac{1}{u} - \dfrac{1}{v} = -\dfrac{1}{f}

Where;

u = The distance from the statue to the mirror

Therefore, we get;

\dfrac{1}{u} = -\dfrac{1}{f} + \dfrac{1}{v}

Plugging in the values gives;

\dfrac{1}{u} = -\dfrac{1}{13.5} + \dfrac{1}{11.5} = \dfrac{8}{621}

∴ The distance from the statue to the mirror, u = 621/8 cm = 77.625 cm.
