Answer:
B
Explanation:
A meter stick measures distances ( like centimeters) so....B
it does NOT measure mass , volume or VERY large distances (Like earth's diameter)
When potassium is added to water the metal melts and floats. It moves around very quickly in the surface of the water.
I'm pretty sure it's Nuclear Reactions. Not very sure.
Answer:
No, I believe it's not balanced, srry if I got it wrong for you
Answer:
resistance = 4 Ω
Explanation:
Data Given:
voltage = 12 volt
current = 3 amps
Resistance of the circuit = to be calculated
Solution:
The resistance of the circuit can be calculated by Ohm's law formula.
Resistance have a unit that is ohm (Ω)
Ohm's formula
R = V/I
Where
R = resistance
V = voltage
I = current
Put value in the above formula
R = 12 volt / 3 amps
R = 4 (volt/amps)
R = 4 Ω
Unit of Resistance
R = volt / amps = Ω
So, resistance = 4 Ω
