resistor has a resistance of 1.8 W. How much current passes through the resistor if there is a potential difference of 3.0 V across the resistor?

the solar system used to have much dust particles option no d

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.
