What causes clouds to form on the upwind side of mountain ranges

Physics
1 answer:
Makovka662 [10]2 years ago
8 0
I believe it’s because of the air from the lower part of the mountain adjusting to the climate at the top. Mountains cause air to rise, and when that air rises it cools down creating the clouds.

Hope I helped!

a bullet moving with a velocity of 100m/s pierce a block of wood and moves out with a velocityof 10 m/s.if the thickness of the
erma4kov [3.2K]

The emerging velocity of the bullet is <u>71 m/s.</u>

The bullet of mass <em>m</em> moving with a velocity <em>u</em>  has kinetic energy. When it pierces the block of wood, the block exerts a force of friction on the bullet. As the bullet passes through the block, work is done against the resistive forces exerted on the bullet by the block. This results in the reduction of the bullet's kinetic energy. The bullet has a speed <em>v</em> when it emerges from the block.

If the block exerts a resistive force <em>F</em> on the bullet and the thickness of the block is <em>x</em> then, the work done by the resistive force is given by,

W=Fx

This is equal to the change in the bullet's kinetic energy.

W=Fx=\frac{1}{2} m(u^2-v^2)......(1)

If the thickness of the block is reduced by one-half, the bullet emerges out with a velocity v<em>₁.</em>

Assuming the same resistive forces to act on the bullet,

F(\frac{x}{2} )=\frac{1}{2} m(u^2-v_1^2)......(2)

Divide equation (2) by equation (1) and simplify for v<em>₁.</em>

\frac{\frac{Fx}{2} }{Fx} =\frac{(u^2-v_1^2)}{(u^2-v^2)} \\\frac{100^2-v_1^2}{100^2-10^2} =\frac{1}{2} \\v_1^2=5050\\v_1=71.06 m/s

Thus the speed of the bullet is 71 m/s

Final velocity will be greater than initial velocity of an object is
Natali [406]

Answer:

accelerating

Explanation:

If we consider(v > u) Acceleration:

final velocity(v)= 14m/s

initial velocity(u)=10m/s

time taken(t)= 2 seconds

a= \frac{(v-u)}{t} =\frac{(14-10)}{2}=2m/s²

If we consider (v<u) Deceleration:

final velocity(v)= 3m/s

initial velocity(u)=9m/s

time taken(t)=2 seconds

a= \frac{(v-u)}{t}=\frac{(3-9)}{2}= -3m/s²

The greenhouse effect that raises the surface temperature of planets
PSYCHO15rus [73]

Answer:

c

Explanation:

Green house effect:

 Temperature of atmosphere is going to  increased continuously, because infrared light absorbed by gas .This increased in temperature atmosphere    is called green house effect.

The green houses gases are as follows

,Carbon diaoxide,water vapor  ,,Carbon diaoxide ,Methane ,,Carbon diaoxide oxide,CFCs ,ozone.

So the option c is correct.

Why do scientist use models to study atoms
Vedmedyk [2.9K]
Scientists use models to study atoms, Because atoms are very tiny, and almost impossible to cut open and look inside.. And the center of an atom is the nucleus and that is ever smaller.
