How to corvert 0.75kg to milligrams!! SOME HELP PLZ!!?
also convert: 825000 millimeters to km 1.92 km to centimeters... Can u expleain please!! Thank You....

0.75kg x (1000g / 1kg) x (1000mg / 1g) = 7.5x10^5 mg 825000mm x (1m / 1000mm) x (1km / 1000m) = 0.825 km 1.92km x (1000m / 1m) x (100cm / 1m) = 1.92x10^5 cm ********* do you understand this? Answered by Wen Chuba 2 years ago.
.75kg= 750000 mg. you know that 1kg= 1000g. so how many grams make .75kg? ---> 7500 grams. and 1gram= 1000mg. So 7500 x 1000 = 750000mg. and same with the other two problems. 825000mm= .825 km. [1km=1000000mm] 1.92km= 192000cm [1km=100000cm] since this is chemistry, beware of significant figures! I couldn't explain it using the negative exponents which would've been easier, but hope this helps! Answered by Lael Coyazo 2 years ago.

What effect would an increase in duration of the action potential have on the duration of the absolute refractory period? Ok, so if we were to administer potassium channel blocker drugs to a patient, these would increase the duration of the AP since we dont have the usual rapidness of hyperpolarization. As a result, then the ERP would be increased as would the ARP, correct? For what are these types of drugs used? ( I haven´t yet had pharm ). Any help is appreciated.

Potassium channel blockers are used in the treatment of cardiac arrhythmia and are classified as class III antiarrhythmic agents. These drugs bind to and block the potassium channels that are responsible for phase 3 repolarization. Therefore, blocking these channels slows (delays) repolarization, which leads to an increase in action potential duration and an increase in the effective refractory period (ERP). Drugs in this class include amiodarone (Cordarone), dronedarone (Multaq), bretyllium (Bretylol), sotalol (Betapace), ibutilide (Corvert) and dofetilide (Tikosyn).
