What is the magnification of a real image if the image is 15.0 cm from a lens d
and the object is 60.0 cm from the lens? Use the equation m=-
d
A. 0.25
B. -4.0
C. 4.0
D. -0.25
O

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

not moving. pos accel,
