When water in clouds undergoes condensation, it can lead to?
olga_2 [115]
It will lead to rain. I know this because as the clouds move over water sources like oceans, lakes, and rivers, the water evaporates and rises. The water then liquefies into little water droplets. As the cloud moves over more water the droplets get scrunched up and get bigger over time and soon they get heavy and gravity pulls the droplets down to earth as rain. The End.

A 1.4 kg block slides across a rough surface such that it slows down with an acceleration of 1.25 m/s(squared). What is the coef
tino4ka555 [31]
F = ma 

<span>where </span>

<span>F = frictional force </span>
<span>m = mass of the block = 1.4 kg (given) </span>
<span>a = acceleration of the block = 1.25 m/sec^2 (given) </span>

<span>Substituting values, </span>

<span>F = (1.4)(1.25) </span>

<span>F = 1.75 N </span>

<span>By definition, </span>

<span>F = (mu)(Normal force) </span>

<span>where </span>

<span>mu = coefficient of friction </span>
<span>Normal force = mg = 1.4*9.8 = 13.72 </span>

<span>Again, substituting appropriate values, </span>

<span>1.75 = mu(13.72) </span>

<span>mu = 0.128</span>
