If a clock expends 2 W of power from a 1.5 V battery, what amount of current is supplying
the clock?
solution 
as we know 
p=vi
i=p/v
=2/1.5
=1.3A
        
             
        
        
        
A force vector F1 points due
east and has a magnitude of 200 Newtons, A second force F2 is added to F1. The
resultant of the two vectors has a magnitude of 400 newtons and points along
the due east/west line. Find the magnitude and direction of F2. Note that there
are two answers.
<span>The given values are
F1 = 200 N</span>
F2 =?
Total = 400 N
Solution:
F1 + F2 = T
200 N + F2 = 400N
F2 = 400 - 200
F2 = 200
N
