Bro Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.

3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the
eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$R = \frac{V}{I}

Now we have to plug in the values as,

$ R = \frac{150}{2.34}

   = 64.1 Ω

So the resistance of the appliance is 64.1 Ω.
