How do you find the period of a Ferris wheel?
How do you find the period of a Ferris wheel?
The center of the Ferris Wheel is minimum + A = 3+20 = 23 ft = D. Substitute t=4.5 to solve for part b. (Note: I did this problem in radians. If you want to use degrees, then the equation for B is period = 360/B.
How long does it take the Ferris wheel to complete one full rotation?
20 minutes
How do you find the phase shift of a degree?
The phase shift equation is ps = 360 * td / p, where ps is the phase shift in degrees, td is the time difference between waves and p is the wave period. Continuing the example, 360 * -0.001 / 0.01 gives a phase shift of -36 degrees.
What is another name for a phase shift math?
In mathematics, a horizontal shift may also be referred to as a phase shift.*(see page end) The easiest way to determine horizontal shift is to determine by how many units the “starting point” (0,0) of a standard sine curve, y = sin(x), has moved to the right or left.
What is phase difference between current and voltage?
The phase difference is <= 90 degrees. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage.
What is a phase angle?
It describes the phase shift between total voltage and total electric current. In the voltage triangle this matches the phase shift between total voltage and active voltage. For the resistance triangle the phase shift lies between the impedance and effective resistance vector.
What is a healthy phase angle?
17º in healthy subjects. PA values were significantly positively correlated with body mass index (BMI) (r= 0.011, P<0.001). The phase angle values for males and females were 7.43±0.98º and 7.05±1.1. 58º, respectively.
What is a good body phase angle?
In a healthy body, an ICW:ECW ratio of 3:2 is considered ideal.
How do you find power angle?
Power Triangle of an AC Circuit
- Where:
- P is the I2*R or Real power that performs work measured in watts, W.
- Q is the I2*X or Reactive power measured in volt-amperes reactive, VAr.
- S is the I2*Z or Apparent power measured in volt-amperes, VA.
- Φ is the phase angle in degrees.
- Cos(Φ) = P/S = W/VA = power factor, p.f.
What is the power angle?
Power angle: For a generator, the power angle is the difference between the generator induced voltage and the generator terminal voltage. Power angle is the angle between a generator’s internal voltage and its terminal voltage, or between the voltages at the source and load points of an electrical transmission line.
How do you solve apparent powers?
- The difference between VA and Watts.
- Definitions.
- Apparent power, which is the product of rms (root mean square) volts.
- Real power, which is the time average of the instantaneous product of.
- Reactive power, which is the time average of the instantaneous product.
- P = V x A = VA.
- P = 120 V x 6 A = 720 Watts.
