Hello!
Use <u>ohm law:</u>
I = V / R
Replacing:
I = 100 V / 20 O
I = 5 A
The current is <u>5 amperes.</u>
Answer:
An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).

Answer:
Storing it at a temperature greater than its Curie temperature will demagnetize it. The Curie temperature--named after the French scientist Pierre Curie--is the temperature at which magnets lose their permanent magnetism. ... Samarium cobalt, neodymium, and ceramic/ferrite magnets are brittle.
C. A combined circuit
That’s the answer
