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.
Answer:
Explanation:
= Charge at 3000 m = 40 C
= Charge at 1000 m = -40 C
= 3000 m
= 1000 m
k = Coulomb constant = 
Electric field due to the charge at 3000 m
Electric field due to the charge at 1000 m
Electric field at the aircraft is 
.
Answer: planetary nebula phase, and white dwarf phase
Explanation:
Answer:
2666.67 m
Explanation:
Changing the 8km/s into SI units we 8000m/s.
Speed of a wave = λf where λ is the wavelength and f he frequency of the wave.
v=λf
Therefore making wavelength the subject of the formula we get
λ= v/f
Substituting with the values in the question we get:
λ= (8000m/s)/3Hz
=2666.667 m
Since it moves 5 m/s faster every second, after 20 seconds it's moving 100 m/s faster than when it started speeding up.
If it was moving at 14 m/s when the acceleration began, it's moving at 114 m/s at the end of the 20 seconds. Its velocity is <em>114 m/s North.</em>
That's 255 mph !
