I think it’s false bc A volcano is not in the interior of the earth
Answer:
Motors commonly contain a "commutator" which allows a magnetic field due to a loop of wire to always be in a say "clockwise or counterclockwise" direction even tho the loop of wire is rotating.
That means that magnetic field due to the surrounding magnets is always in the same direction, but the magnetic field due to the rotating loop of wire is continually changing so that it will always oppose the surrounding field which remains in a constant direction.
This is most easily seen in a "DC - direct current motor".
yes. gravity is working on you and everything on you.
also earth is rotating
no not in respect ofimmediate surroundings
object could move at constant velocity = no change in either magnitude or direction
change of position "proves" this
The force of gravity is the
force with which massively large objects such as the earth attracts another
object towards itself. All objects of the earth exert a gravity that is
directed towards the center of the earth. Therefore, the force of gravity of
the earth is equal to the mass of the object times acceleration due to gravity and also equal to the weight of the object.
F = ma
since F = W
W = ma
For the researcher to accurately measure the dependent variable [which is quantity of mold growth produced] she will need to learn how to quantitatively measure mold growth. The correct option is D. Since the researcher has decided to measure the quantity of mold growth produced by both white and wheat bread, she must devise an effective and accurate mean of measuring the quantity of growth produced by the breads, this will enable her to subject the two breads to the same experimental conditions.
