Answer:
the average induced emf in the second winding is
Explanation:
The magnetic field inside the first solenoid is given by,
Where is the permeability of the free space
N is the number of turns of solenoid per unit length
I is the current in the solenoid
A is the cross-sectional area of the wire
Replacing we have,
Thus average emf induced in the second windigs is,
Therefore the average induced emf in the second winding is
The thickness of the ozone layer (for earth) and the atmosphere.
Mercury is the closest planet to the sun but it isn’t the hottest because it has no atmosphere. Although Venus is the second planet from the sun, it is the hottest because of it’s thick atmosphere and the clouds that trap heat in.
You've definitely got the right idea and your procedure is correct.
But I see one mistake for sure, plus a few other things that
I'm not sure of.
The mistake for sure: If the ending water is 12 ml,
then the beginning water is 9 ml, not 11 ml.
Things I'm not sure of:
-- I'm not sure that I'm remembering correctly at the moment,
but I have a sneaking hunch that you're supposed to read the
level at the BOTTOM of the meniscus, not the top.
It won't matter, because the DIFFERENCE will be the same
either way. But if the teacher wants you to read from the bottom,
then your numbers may be marked wrong.
-- The question at the bottom asks for the "volume of cherry",
but I seem to see TWO cherries in the water. Does than mean
they expect you to take only half of the displacement ?
-- They ask for "volume of cherry" twice.
Maybe that means they want you to end up with the volume in cm³
instead of ml. (The number is the same.)
