Answer:
The magnet will exert a force on the electric current
Explanation:
The electric current flowing through the cord will experience magnetic force due to presence of magnetic field created by the magnet brought near it.
The magnitude of the magnetic force experienced by this flowing current is given as;
F = qvB
where;
q is charge of electron (measured in coulomb's, C)
v is the speed of the flowing current (m/s)
B is the magnetic field strength (T)
Therefore, the magnet will exert a force on the electric current
The concentration by mass means that the mass of solute in a given amount of solution. So for the a), the concentration should be 17/(17+183)*100%=8.5%. For b), the concentration should be 30/(30+300)*100%=9.09%.
Answer:
A. Distance from the moon.
The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
