Answer:
Over Here
Explanation:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
<span>umm it gives 1/v + 1/20 = -1/10 and v = -20/3 cm. Magnification = |v/u|=1/3.</span>
12.5 = 100 * (1/2)^n
divide by 100:
0.125 = (0.5)^n
this is equivalent to:
, which equals 3.
(since 0.5 cubed = 0.125)
