As air rises, why do clouds form?

Physics
1 answer:
MissTica3 years ago
3 0

Answer:

C. the air cools to its dew-point temperature and condenses into liquid water

Explanation:

Clouds are formed when the air rises heated by terrestrial irradiation. As it warms, the air rises and rises until it reaches its dew point, which will be when the water vapor condenses on (dew) or ice crystals. These droplets, which have a spherical shape and measure between 0.004 and 0.1 mm, are in continuous motion when they are suspended in the air and when they are subjected to updrafts, so they collide with each other and group together. Depending on the atmospheric conditions, an increase in their thickness may occur so as to cause them to precipitate.

Answer:

v = 12.86 km/h

v = 3.6 m/s

Explanation:

Given,

The distance, d = 13.5 km

The time, t = 21/20 h

                  =  1.05 h

The velocity of a body is defined as the distance traveled by the time taken.

                                     v = d / t

                                        =  13.5 km / 1.05 h

                                        = 12.86 km/h

The conversion of km/h to m/s

                                   1 km/h = 0.28 m/s

                                     12.86 km/h = 12.86 x 0.28 m/s

                                                         = 3.6 m/s

Hence, the velocity in m/s is, v = 3.6 m/s

What is the displacement of the runner in 4 laps? *<br> 2 point
Serhud [2]

Answer:

There is no displacement.

Explanation:

Because the runner is running laps and returning to the original place, there is no displacement as displacement is relative to the change in location from the original position.

Hope this helps. . .

A satellite completes one revolution of a planet in almost exactly one hour. At the end of one hour, the satellite has traveled
ad-work [718]

Answer:

shown below

Explanation:

2 x 10⁷ as a number is 20,000,000

20,000,000 - 10 = 19,999,990

It went 19,999,990 m/h

in km/h:

19,999,990 / 1000 = 19,999.99 km/h

in km/s

19,999,990 / 3,600,000 = ~5.56 km/s

in m/s

19,999,990 / 3600 = ~5555.56 m/s

I have four questions.
Inga [223]

Answer:

The potential energy of the ball is 784 joules. And the kinetic energy of it is 392 while falling halfway down.

Explanation:

PE = mass (2kg) * Gravitational acceleration (9.8 m/s^2)* height (40 meters)

KE = 1/2 mass (1 kg) * velocity^2 (19.8)
