If a = v^2/r, then v = plus or minus the square root of a times r
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 calculating power (p) in a system is p v2/r, where v represents velocity and r represents radius.
The formula for centripetal acceleration is a v2 / r, where a is the centripetal acceleration, v is the velocity, and r is the radius.
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.
The formula for centripetal acceleration is a v2 / r, where a is the acceleration, v is the velocity, and r is the radius of the circular path.
The formula for centripetal acceleration is a v2 / r, where "a" is the centripetal acceleration, "v" is the velocity, and "r" is the radius of the circular path.
Centripetal acceleration can be calculated using the formula a v2 / r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path.
To find the centripetal acceleration, use the formula a v2 / r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path.
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.
