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 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 a compound graph?
A Compound Graph is an extension of a standard graph. Let G be a graph, G=(V,E) where V is a set of vertices and E is a set of edges, that is e = (v1, v2) in V2 A compound graph C is defined by a tree T=(V,F) where V is the same set as G and F are tree edges f=(v1,v2) in V2. C=(G,T) where G=(V,E) and T=(V,F) Furthermore, C has two additional constraints: e=(v1,v2) in E implies: 1) v1 is not on the path of v2 to the root of T AND 2) v2 is not on the path of v1 to the root of T. Intuitively, T defines a hierarchy. All the vertices sharing the same parent in T are in the same "group". The constraints state that you cannot have an edge connecting a vertex to one of its parent in the hierarchy.
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 chemical formula for vanadium V chromate?
The chemical formula for vanadium(V) chromate is V2(CrO4)5.
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.
How can you solve for resistance when given power?
You can solve for resistance using the formula ( R = \frac{V^2}{P} ), where R is the resistance, V is the voltage, and P is the power. By rearranging the formula, you can solve for resistance by dividing the square of the voltage by the power.
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 determining electrical power?
Electrical power (P) can be calculated using the formula P = V x I, where V is the voltage in volts and I is the current in amperes. Alternatively, power can also be calculated as P = I^2 x R, where R is the resistance in ohms.
What is the formula for vanadium v sulfate?
The chemical formula for vanadium(V) sulfate is V2(SO4)3. It consists of two vanadium atoms bonded to three sulfate ions.
Electromagnet current of o5 a supply is 12v what resistance does the electromagnet have?
Using Ohm's Law (V = I * R), where V is voltage, I is current, and R is resistance, we can rearrange the formula to solve for resistance: R = V / I. In this case, R = 12V / 0.5A = 24 ohms. So the resistance of the electromagnet is 24 ohms.
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 would you rearrange this algebra formula?
v=1/4(squareroot)a/2b make A the subject
When using a 60.0 W light bulb in a household circuit what is the resistance?
To calculate the resistance of the 60.0 W light bulb, you need to know the voltage of the household circuit. Using the formula P = V^2 / R (where P is power in watts, V is voltage in volts, and R is resistance in ohms), you can rearrange to solve for resistance: R = V^2 / P. Substitute the given power (60.0 W) and the voltage of your household circuit to find the resistance.
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
