Answer:
Explanation:
They need a galvanic difference. Or saying that less technically, they need to have different electron attraction, so that one can collect electrons (oxidation/reduction) and flow current from the other. :)
Answer: 51N
Explanation: T = mv^2/r 51 = 76v^2/1.3 v =.934
Answer:
5/6 MR²
Explanation:
In the composite object, the distance from the disk's axis to the rod's axis is R/2. Using parallel axis theorem, the rod's new moment of inertia is:
I = 1/12 MR² + M (R/2)²
I = 1/12 MR² + 1/4 MR²
I = 1/3 MR²
The total moment of inertia is therefore:
I = 1/2 MR² + 1/3 MR²
I = 5/6 MR²
