Answer:
Rotating the coil faster
Increasing the number of coils
Using stronger magnets
Answer:
Explanation:
Electric field due to a finite wire at some distance "x" from it on its perpendicular bisector is given by the formula
so here we will have
now we know that
F = qE
we will have
so we will have
so total charge on the rod is given as
The answer is A) solid iron at 25.C
The name is fluorine-19.
Usually, in the names of isotopes, we say the name of the element followed the mass number (eg. Carbon-12). The mass number is the sum of the number of protons and neutrons of that atom. Electrons are not included since they're too light compared to protons and neutrons.
Therefore, to find out the name of the isotope, we have to find the mass number. Add up 9 and 10, which makes 19, so, the answer is fluorine-19.
