C.) a magnetic field is the correct answer…
Answer:
E
Explanation:
Using Coulomb's law equation
Force of the charge = k qQ /d²
and E = F/ q
substitute for F
E = ( K Qq/ d² ) / q
q cancel q
E = KQ / d²
so twice the distance of the from the point charge will lead to the E ( electric field ) decrease by a 4 = E/4. E is inversely proportional to d²
The recessive trait will always show up
The focal point of a concave mirror is halfway along the radius, therefore the radius would be 2•16= 32 cm
