To find the radius of a cylinder when the volume is 2500 and the height is 16, you can use the formula for the volume of a cylinder: V = πr^2h. Given that V = 2500 and h = 16, you can rearrange the formula to solve for the radius: r = √(V / (πh)). Plugging in the values, you get r = √(2500 / (16π)) ≈ √39.56 ≈ 6.29. Therefore, the radius of the cylinder is approximately 6.29 units.

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.
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
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.
The chemical formula for vanadium(V) chromate is V2(CrO4)5.
W=watts, V=volts, I=amps or current, R=resistance W = V x I or, W = I2 x R or, W = V2 / R.
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.
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.
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.
The chemical formula for vanadium(V) sulfate is V2(SO4)3. It consists of two vanadium atoms bonded to three sulfate ions.
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.
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.
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.

R=i/v If R = resistance, i = current and v = voltage, the formula is incorrect. It should be: R = v/i
