Put a fork under your pillow tonight, and your wish will come true tomorrow.
V=IR therefore I=V/R=10/50=0.2A therefore the current is 0.2 A
Answer:
The angular magnification is 
Explanation:
From the question we are told
The focal length is 
The near point is 
The angular magnification is mathematically represented as

Substituting values

The bigger the object the greater the gravitational pull, so the farther away the big object is its gravitational force begins to decrease. Refer to the picture for more explanation.
