How do you prepare 5 picomole solution from 32nanomole solution?
5 * 10**-12 mol 32 * 10**-9 mol Concentration (M) * Volume (L) = mols C1*V1=C2*V2 (5*10**-12)*V1=(32*10**-9)*V2 (5*10**-12)*V1/(32*10**-9)=V2 (5*10**-3)*V1/32=V2 The volume of the 5 picomolar solution that you wish take = V1 The volume of the 32 nanomolar solution that you need to make V1 at 5pM concentration = V2 Take V2, and place into graduated cylinder and fill to V1.
What is the average velocity when a person traveling on a straight line moves with a uniform velocity v1 for x distance and v2 for next equal distance?
Let t1 and t2 be the times for the two stages. Then t1 = x/v1 and t2 = x/v2 Total distance = x + x = 2x Total time = t1 + t2 = x/v1 + x/v2 = x*(1/v1 + 1/v2) Average velocity = total distance / total time = 2x divided by x/(1/v1 + 1/v2) = 2(1/v1 + 1/v2) which is the Harmonic mean of v1 and v2.
Is Lvh with repolarization abnormality dangerous?
LVH (left ventricular hypertrophy) is represented by classic EKG findings, namely that the sum of V1Q and V5R > 35 mm (ie: a very deep Q wave in V1 and a very tall R wave in V5). Further, you will expect to find left axis deviation as represented by tall R waves in both lead II and aVL. LVH is one of many conditions (including bundle branch blocks) that can also have repolarization abnormalities. Simply put, a repolarization abnormality is shown on EKG with a T wave going the opposite direction as the main direction of the QRS. Recall, normally these will be in the same direction despite the fact that the QRS is ventricular depolarization and the T wave is ventricular repolarization, because they occur in opposite directions.
A weather balloon full of helium with a volume of 47.1 L at 22oC is sitting inside an aircraft hangar The temperature of the hangar increases to 33oC Which equation would be easiest to use to find t?
(v1/t1) = (v2/t2)

What does the v stand for in V1-V6 of a EKG?
Vector
What is the percent increase from 12.00 to 18.00?
Percentage change from V1 = 12 to V2 = 18:[ ((V2 - V1) / |V1|) * 100 ]= ((18 - 12) / |12|) * 100= (6 / 12) * 100= 0.5 * 100= 50% change= 50% increase
What are posterior lead in ecg?
V7-9 placed around the back. They're rarely used. II, III aVF -> inferior V5, V6, I, aVL -> lateral V1, V2 -> septal V3, V4 -> anterior

What does a small p wave on a ecg mean?
nothing... a nonexistent Q wave represents a possible heart attack in the past in the location of whatever lead its in. However, patients that are barrel chested or just plain big can throw off an EKG.
How do you get gozerotchi on the tamagotchi v1?

Diagram of ECG placement for dextrocardia?
Right limb leads to left limbs and vice versa with other side. Chest leads run from v1 left sternal to v6 right lateral usingsame landmark placement
What is the formula for percentage change?
[ ((v2 - v1) / |v1|) * 100 ]
In the acceleration equation what do v1 and v2 represent?
v1 = initial velocity v2 = final velocity
Charles Law formula?
Relates that if held under constant pressure the ratio of Vol/Temp remains constant. i.e, V1 / T1 = V2 / T2 (where T is in Kelvin)
What is the equation for the percentage difference of 20 and 31?
( | V1 - V2 | / ((V1 + V2)/2) ) * 100
