A path that allows only one route for an electric current is called a Series circuit. A series circuit is circuit that's arranged in a chain making it to where there's only one path to take
Answer:
Explanation:
Resistivity is given by where A is cross-sectional area, R is resistance, L is the length and is the reistivity. Substituting 0.0625 for R, 3.14 × 10-6 for A and 3.5 m for L then the resistivity is equivalent to
Answer:
P = 90 W
Explanation:
Mass of an object, m = 30 kg
Speed of the object, v = 15 m/s
Distance, d = 10 m
Work done, W = 900 J
Time, t = 10 s
We need to find the power generated by this project. We know that power is equal to work done divided by time taken.
So,
So, the required power generated is 90 W.
Answer:
D. I'm guessing
The gold-foil experiment showed that the atom consists of a small, massive, positively charged nucleus with the negatively charged electrons being at a great distance from the centre.
