An important difference between a universal and a split-phase motor is that the split-phase motor has
A. two brushes attached to the stator.
B. a single coil formed on the rotor.
<u>C. two windings on the stator. </u>
D. an armature with a commutator.
Explanation:
There are three forces on the bicycle:
Reaction force Rp pushing up at P,
Reaction force Rq pushing up at Q,
Weight force mg pulling down at O.
There are four equations you can write: sum of the forces in the y direction, sum of the moments at P, sum of the moments at Q, and sum of the moments at O.
Sum of the forces in the y direction:
Rp + Rq − (15)(9.8) = 0
Rp + Rq − 147 = 0
Sum of the moments at P:
(15)(9.8)(0.30) − Rq(1) = 0
44.1 − Rq = 0
Sum of the moments at Q:
Rp(1) − (15)(9.8)(0.70) = 0
Rp − 102.9 = 0
Sum of the moments at O:
Rp(0.30) − Rq(0.70) = 0
0.3 Rp − 0.7 Rq = 0
Any combination of these equations will work.
Answer: The area of the rectangle is 72.12 square meters
Explanation:
The area of the rectangle is length x width
Area = 6.01 m x 12 m = 72.12 m²
Here (X) is a parallel combination of resistors whereas it is series combination of resistors in (Y).

Accuracy
Explanation:
Accuracy is a term that refers to the exactness of a measurement.
Accuracy is the nearness of measured value to the true value.
The difference between the measured value and the true value is the uncertainty in the measurement.
- The closer a measured value is to the true value, the more accurate the measurement is. The lesser the error accrued in the process.
