-identifies an electric charge 
-it can identify its polarity (positive or negative) if you compare it to a charge that you already know
-can identify the magnitude of a charge (how big of a charge it is)

Answer:
13.875 T
Explanation:
Parameters given:
Length of solenoid, L = 2.5 cm = 0.025 m
Radius of solenoid, r = 0.75 cm = 0.0075 m
Number of turns, N = 25 turns
Current, I = 1.85 A
Magnetic field, B, is given as:
B = (N*r*I) /L
B = (25 * 0.0075 * 1.85)/0.025
B = 13.875 T
 
        
             
        
        
        
It's one of your hands.  Which one it is depends on how you sweep.
-- If you hold the top of the stick motionless and wave your bottom hand 
back and forth, then your top hand is the fulcrum, and you're using the 
broom as a Class-3 lever. 
-- If you hold your bottom hand motionless and wiggle the top end of the 
broom back and forth with your top hand, then your lower hand is the fulcrum, 
and you're using the broom as a Class-1 lever.
        
                    
             
        
        
        
Correct answer is:
<h2>The maximum number of orbits in an atom is <u>Seven.</u></h2><h3>Explanation:</h3>
Every energy level has a limited one orbital including two electrons. The orbits are settled in the sub-levels and there can be further than 1 sub-level as the number of energy levels rises. On energy level 1, there is 1 sub-level and 1 orbital. Energy level 2 can possess 2 sub-levels and 2 orbitals. These remain to develop as you progress from the nucleus of the atom, closing up with an infinite potential number of levels and orbits.
