No work is done because the object needs to be moved. The formula for work is Work = Force x Distance.
It's D. If it absorbed it would be turning to steam. I am taking honors chem in high school we are learning this.
I know for a fact the answer is D. the distance traveled by the wave during one full cycle
Answer:
R = 7 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance. In this way, we have the following equation.
V = I*R
where:
V = voltage = 49 [V] (units of volts)
I = current = 7 [amp] (amperes)
R = resistance [ohms]
Now clearing R.
R =V/I
R = 49/7
R = 7 [amp]
