Young offenders, jail, fines, license troubles, DUI, and punishments
Answer:
<em>0.0386 hr</em>
<em></em>
Explanation:
Area = 565 cm^2 = 0.0565 m^2 (1 cm^2 = 0.0001 m^2)
flux state rate = 220 mole/m^2-day
<em>There are 24 hrs in a day,</em> therefore rate in hrs will be
220/24 = 9.17 mole/m^2-hr
mass of water = 0.4 kg
molar mass of water = (1 x 2) + 16 = 18 kg/mole
therefore,
<em>mole of water = mass of water/molar mass of water</em>
mole of water = 0.4/18 = 0.02 mole
<em>mole flux = mole/area</em> = 0.02/0.0565 = 0.354 mol/m^2
<em>time that will be taken will be for water to pass = mole flux/mole flux rate</em>
time = 0.354/9.17 = <em>0.0386 hr</em>
Answer:
(a) pulse-amplitude modulation (PAM)
Explanation:
It should be no surprise that pulse amplitude is modulated in <em>pulse-amplitude modulation (PAM)</em>.
