Describe the water cycle process starting from an afternoon thunderstorm. There are many different variations that could happen.
spin [16.1K]

Explanation:

The water cycle basically involves five steps:

  • evaporation and transpiration ⇄
  • condensation, ⇄
  • precipitation, ⇄
  • runoff, ⇄
  • infiltration ⇄

So when a <u>thunderstorm </u>occurs it <em>helps in completing the precipitation process </em>by enabling the release of water vapor stored up in the atmosphere to fall on the ground as rain.

After this, the water <em>runoffs </em><em>to the surface of the ground, on plants, into rocks, rivers, and lakes.</em>

Next, the <em>Infiltration process</em> enables the water on the ground surface to enter the soil some of which becomes groundwater.

The cycle begins again as the<em> </em><em>evaporation and transpiration</em> <em>process </em>begins, where the groundwater as a result of heat from the sun is taken back into the atmosphere, while water in plants by means of transpiration goes back <em>into the atmosphere</em>.

It then <em>condenses </em>and falls back as precipitation again.

You can use any coordinate system you like in order to solve a projectile motion problem. To demonstrate the truth of this state
Aleks04 [339]

Explanation:

It is given that,

Height of the building, h = 44 m

Initial horizontal velocity, u_x=ucos\theta=8.6\ m/s

Initial vertical velocity, u_y=usin\theta=10.5\ m/s

It can be assumed to find the maximum height of the projectile and time taken to reach the maximum height.

The formula for the maximum height is given by :

H=\dfrac{(u\ sin\theta)^2}{2g}

g is the acceleration due to gravity

H=\dfrac{(10.5)^2}{2\times 9.8}=5.625\ m

The total maximum height, h' = h + H

h'=44+5.625=49.625\ m

The formula for the time of flight is given by :

t_{max}=\dfrac{u\ sin\theta}{g}

t_{max}=\dfrac{10.5}{9.8}=1.07\ s

Hence, this is the required solution.
