V1, V2, and VTOT are terms commonly used in aviation. V1 is the decision speed during takeoff, beyond which the pilot must continue the takeoff even if an engine fails. V2 is the takeoff safety speed, ensuring the aircraft can safely climb after a failure. VTOT refers to the total takeoff velocity, which encompasses both V1 and V2, indicating the speed at which the aircraft is expected to lift off the runway.

Why there is algebric sum of the resistances in the series combination?
Ohms Law will be helpful in seeing how resistances add up. Let's assume you have a 10 ohm and a 20 ohm resistor in series and 30 Volts. across the series. Ohm's Law states that Voltage = Resistance x Current. If we describe the 10 ohm resistor as R1 and the other as R2 then the voltage drop across R1 is V1 and V2 is the drop across R2. This can be written V1 = R1 x I1 and V2 = R2 x I2. Since the total voltage must equal the sum of the voltage drops then Vtot = V1 + V2. Also Itot = I1 + I2. Substituting we get Vtot = (I1 x R1) + (I2 x R2) = (I1 + I2) x (R1 + R2). And Vtot = Itot x Rtot so Rtot = R1 + R2. In example 30 Volts = Itot x (10 + 20) or Itot = 1 amp.

What is the advantage of a system with more than one type of output?
The most common multi output systems are used for getting differential output. i.e., if V1 and V2 are the 2 outputs, then usually the difference, V2-V1 or V1-V2 is used.
If acceleration=0, than according to "d=v2*t-1/2a*t^2" changed to get v2 is "v2=d+1/2a*t^2/t", but with acceleration=0, would v2=d V2=end velocity, d=distance, a=acceleration, t=time?
The equations of motion that relate velocity, distance, time and acceleration for the specific case of "constant acceleration" can be written as follow, acceleration a = (v2 - v1)/t from which v2 = v1 + at The distance covered during t time d = vav x t, where vav refers to average velocity in the process from v1 to v2. For the case of constant acceleration vav = (v1 + v2)/2. Substituting in d we get d = (v1 + v2)/2 x t from which, v2 = 2d/t - v1 If we take the constant acceleration to be zero, a = 0, you can see that the second equation we wrote becomes, v2 = v1 (There is no acceleration), so our equation for the distance d becomes, d = v1 x t = v2 x t
What is the minimum numbers of unequal vectors to result into a null vector?
Two vectors; V1 + V2=0 where V1= -V2, two opposite vectors.
Which missile was bigger V1 or V2?
the V2 rocket was bigger and faster than the V1 flying bomb. the V1 being a flying bomb was smaller and had a pulse jet engine and the V2 which was a rocket had a bigger rocket engine. ACTUAL SIZE COMPARISON: V1: Length: 25' 4" wingspan: 8.32 meters V2: length 14 m (45 ft 11 in)
How do you find the shrinkage ratio?

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.
