The density of aluminum is 2.7 g/ml.
Power in a wire where current is flowing can be calculated from the product of the square of the current and the resistance. Resistance is equal to the product of resistivity and length divided by the area of the wire. We do as follows:
Resistance = 2.44 × 10-8 ( 0.11) / (π)(0.0009)^2 = 1.055x10^-3 <span>Ω
P = I^2R = .170^2 (</span>1.055x10^-3 ) = 3.048x10^-5 W
Answer:
A theory or hypothesis does not necessarily provide an accurate scientific explanation to any topic but predicts what can happen.
Explanation:
Answer: One of the signs a chemical reaction is taking place is the presence of bubbles. :)
