Answer:
Looks like A but I'm not sure.
Explanation:
dont take my word for it I might be wrong
The angular frequency in rev/s of the combination when they start rotating together is 1.8 rev/s.
Apply conservation of angular momentum:
Ii.ωi=If.ωf
⇒ 1/2mR² ×3.0=( 1/2mR²+m(2R)²/12)ωf
⇒ωf =1.8rev/s.
A scalar representation of rotation rate in physics is called angular frequency, or "". It speaks of the angular displacement per unit of time, the rate of change of a sinusoidal waveform's phase, or the rate of change of the sine function's argument. The difference between angular frequency (measured in radians per second) and frequency (measured in cycles per second, also known as Hz) is two. Instead of the letter f, the symbol for frequency in this figure is. an axis-centered rotating sphere. Points further from the axis move more quickly, fulfilling = v / r. Angular frequency (), also referred to as radial or circular frequency, calculates the amount of angular momentum per unit of time. Therefore, it is measured in degrees (or radians) per second.

Answer:(a) 0.24v (b) 140.00v
Explanation:I= EMF/R+r= 12.6v/4.00+0.0790 =3.0890A
v=IR=3.0890*4.00=12.35v
V=EMF-v=12.6v-12.356=0.24v
hence potential difference across the headlight bulbs when they are the only load (V) =0.24volts.
(b) v=IR=35.0*4.00=140.00 volts
Hence the potential difference across the headlight bulbs when the starter motor is operated (V) = 140.00volts
Answer:
Their primary way of spreading is from human activities, they can quickly travel around the world for example these new "murder" hornets that can kill a large bee hive with one sting, they traveled all the way from Asia. Invasive species can also be through people's luggage, small boats, planes and large shipment like cargo carriers. I hope this helps. : )
