A lamp that uses 100.0 watts of power requires a voltage of 210.0 volts. What is the resistance of the lamp?

alexandr402 [8]

Resistance = Voltage/Current
Wattage = Voltage * Current

 That means the current drawn by the lamp is equal to 100 watts divided by 210 volts.

Resistance = $\frac{210}{ \frac{100}{210} }$

A Car is travelling at 36ft/s change to miles per hour

AVprozaik [17]

$\frac{36 ft}{1 sec} x \frac{ 1 yd}{3 ft} x \frac{1 mile}{1760 yd} x \frac{60 sec}{1 min} x \frac{60 min}{1 hour} = \frac{129,600 miles}{5,280 hours}$

So, this would simplify to about 25 miles per hour

Hope this is what you were looking for!
