Answer:
Approximately 
.
Explanation:
Note that the electric rate in this question is in the unit dollar-per-
, where 
is the energy to run an appliance of power 
for an hour.
Number of minutes for which the air conditioner is running in that day: 
. Apply unit conversion and ensure that this time is measured in hours (same as the unit of the electric rate.)
.
The power of this air conditioner is:
.
Thus, the energy that this air conditioner would consume would be:
.
At a rate of 
dollar-per-, the cost of that much energy would be approximately 
dollars (rounded to the nearest cent.)
What are the following statements? If there's one that mention a description of current action, or motion, that's your answer.
Lucite has a refractive index of n=1.50. This means that the speed of the light in lucite is decreased according to:
where
is the speed of light in air. Putting the number in the formula, we find that the speed of light in lucite is
The frequency of the light is
, so now we can calculate the wavelength in lucite by using the formula:
<span>Therefore, the correct answer is (2) 393 nm.</span>
Distance = (speed) x (time)
Distance = (10 meter/second) x (2 minutes)
Distance = (10 meter/second) x (2 minutes) x (60 second/minute)
Distance = (10 x 2 x 60) (meter-minute-second / second-minute)
<em>Distance = 1,200 meters</em>
