Answer: earth
Explanation: isn’t earth the only plant with LIQUID water?
Time= 20 minutes= 20*60=1200 s
Charge=current*time=12*1200=14400 C
Answer:
Explanation:you know
circumference of a circle =2*pi*r=?
r=radius of a circle =3m
total distance of 6 revolution =s=6*2*pi*r
again, linear speed =v=s/t=?
t=time =60sec
Answer:
the armature and commutator
Explanation:
An electric generator converts mechanical energy to electrical energy. It is based on the principle that when a conducting coil rotates in the magnetic field, an electric current is generated.
The rotating part is known as Armature. Commutator is cylindrical in shape and connected to armature which rotates with it. It also connects the armature to the external circuit by brushes.
Slip rings are connected to armature coil to maintain an electrical contact with the brushes.
