What is the difference between stable and unstable air?

2 answers:

This is referred to as stable air. If a rising parcel of air is warmer than the surrounding atmosphere it will continue to rise. This is because warm air is less dense or lighter than cool air. This is referred to as unstable air, please mark as brainliest!

In the atmosphere, whether air that is displaced does so in an unstable or stable environment depends upon the vertical temperature profile of the air its lapse rate and upon the moisture content of the parcel. These differences are fundamental to understanding why clouds take up the form they do.

You're driving your pickup truck around a curve that has a radius of 17 m.

Answer:

$v = 10.8 m/s^{2}$

Explanation:

The centripetal force experienced by the steel toolbox is provided by the friction between the toolbox and the bed of the truck.

Therefore,

$\frac{mv^{2} }{r} = f$ --------------------------------(1)

Here,

v - speed of truck

m - mass of toolbox

r - radius of curve around which the truck is turning

f - frictional force

$f \leq$ μmg

In order to obtain Vmax, frictional force must also be max

Thus,

f = μmg--------------------------------------------------(2)

Substitute (2) in (1)

$\frac{mv^{2} }{r} =$ μmg

$v^{2} =$ μgr

g - 9.8 m/ $s^{2}$

The standard value of coefficient of static friction between steel and steel is

μ ≈ 0.7

Therefore,

$v = 10.8 m/s^{2}$

Aleonysh [2.5K]

Answer: 30.641

Explanation: If you get the ave which is 38.0 then the vi which is 7.359

38.0-7.359=30.641/0.0 which is 30.641

20 points for an answer Explain how the distance of a planet from the sun affects the motion of the planet? Justify your respons

Nataliya [291]

The sun’s huge mass gives it a strong gravitational pull. Because of this gravitational pull, planets that are closer to the sun tend to have different motion than planets that are further away from the sun, because the gravity becomes stronger the closer you get. I hope this helped!

The period of a simple pendulum is 3.5 s. The length of the pendulum is doubled. What is the period T of the longer pendulum?

Rudik [331]

Answer:

Explanation:

T = 2π√(L/g)

If you increase L to 2L, the period is increased by a factor of √2

T = 3.5√2 ≈ 4.9 s
