Can unit vector have negative component?
Yes, a unit vector can have negative component since a unit vector has same magnitude and direction as a negative unit vector. Here is the general work out of the problem: Let |v| be the norm of (v1, v2). Then, the unit vector is (v1/|v|, v2/|v|). Determine the "modulus" or the norm |(v1/|v|, v2/|v|)| to get 1, which is the new norm. If we determine the norm of |(-v1/|v|, -v2/|v|)|, we still have the same norm 1.
What is V equals Pi r2h?
V = {pi} r2 h is the formula for the volume (V) of a cylinder of radius r and height h.
What is the radius of a cylinder when you have the voulme and the height?
volume of cylinder = 'pi'. (radius)2.height V = pi.r2.h Note : pi is a constant, value (approx) = 3.1415....... the dot symbol is the multiplication.. to find radius, rearrange the formula for the value of 'r' i hope this helps BY- Narendra Paudel
What is the resistance of a light globe rated 75 W 240 V when it is operating correctly?
The formula for power is W = v2/R therefore the resistance is v2/W where v2 = v*v or v-squared. due to a font fault these formulas cannot be expressed correctly. But the answer to the question is R = 240*240/75 ohms.
What is the formula for calculating watts?
W=watts, V=volts, I=amps or current, R=resistance W = V x I or, W = I2 x R or, W = V2 / R.
What is the formula for determining electrical power?
Power ( in watt) =Voltage (in Volt) x Current (in Ampere) P=V I We Know, V=I R So we can also write, P=I2 R or P=V2/ R
What is the chemical formula for vanadium V chromate?
V2(Cr2O7)5
In centripetal force what is the relationship between v and f if r is kept constant?
Centripetal force has the following formula: Fcentripetal = m times V2/r What that says is that for a constant r in an example, the Fcentripetal is proportional to V2. The centripetal force is proportional to the square of the velocity of the object.
Which has a least resistance 220 volts 100 watts or 115 volts 100 watts?
The higher voltage need more resistance, from the formula W = V2 / R. That means R = V2 / W. So 220 v 100 W is 484 ohms, while 115 v 100 W is 132¼ ohms.
What is the formula for vanadium v sulfate?
V2S5
How would you rearrange this algebra formula?
v=1/4(squareroot)a/2b make A the subject
Which will have higher resistance a 60 watt bulb or a 40 watt bulb?
Assuming the two bulbs are made to run on the same voltage, the one with the smaller power draws less current therefore its resistance is higher. The formula is: R = V2 / W and here V2 indicates V*V (V-squared) until the fault in the font is fixed.
How do find centripetal force?
By newton's second law: force = mass x acceleration. Acceleration can be found by the formula a = v2/r, or alternately, a = omega2 x r (where v is the speed, r is the radius, and omega is the angular velocity in radians/second).
How do you find resistance in a circuit?
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
How do you test for resistance?
R=i/v If R = resistance, i = current and v = voltage, the formula is incorrect. It should be: R = v/i
