Which changes of state do the labels represent? a: b: c:

1 answer:

6 0

A represents the so-called sublimation of state. represents the evaporation, a state change. C stands for melting, a change of state.

<h3>What does evaporation kid mean?</h3>

A liquid turns into a gas through evaporation. Water vapor is created when liquid water evaporation turns it into a gas. Water is helped to evaporate and return to the atmosphere by the heat of the sun. There, it creates a cloud and returns to being water in the form of vapor.

<h3>What exactly happens during evaporation?</h3>

Evaporation is the process by which liquid water transforms into gaseous water (water vapor). Water from the Earth's surface is carried into the atmosphere by evaporation. Evaporation occurs when heat energy causes the bonds holding the water molecules together to fall apart.

The edge of a flying disc with a radius of 0.13 m spins with a tangential speed of 3.3 m/s.

Aleks [24]

By definition, centripetal acceleration is given by:

$a = \frac{v ^ 2}{r}$

Where,

v: tangential disk speed

r: disk radius

Substituting values in the given equation we have:

$a =\frac{3.3^2}{0.13}\\a = 83.76923077$

Rounding the result we have:

$a = 83.8 \frac{m}{s^2}$

Answer:

The centripetal acceleration of the disc edge in m/s^2 is:

$a = 83.8 \frac{m}{s^2}$

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspe

Readme [11.4K]

The true airspeed will increase and true altitude will increase.

<h3>What is true air speed?</h3>

True airspeed is the airspeed of an aircraft relative to undisturbed air.

It's the aircraft speed relative to the airmass in which it's flying.

<h3>How does outside air temperature affect air speed?</h3>

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.

Thus, the true airspeed will increase and true altitude will increase.
