Answer:
no they cannot, only opposite charges attract
Answer:
answer c: a mass and volume
Explanation:
no matter what elements are chosen, they all have a mass and volume measurement I believe
If it attractive it has opposite pole and if it repulsive it has same pole
A window is the most transparent object from these, so that is the answer.
Answer:
Magnitude of induced emf is 0.00635 V
Explanation:
Radius of circular loop r = 45 mm = 0.045 m
Area of circular loop 

Magnetic field is increases from 250 mT to 350 mT
Therefore change in magnetic field 
Emf induced is given by


Magnitude of induced emf is equal to 0.00635 V
