A physical representation of a real object, such as a globe of the world, is a physical model.

Explanation;

-A physical model is a simplified material representation, usually on a reduced scale, of an object or phenomenon that needs to investigated.

-The model can be used to simulate the physical conditions involved (temperature, waves, speed etc.) and to predict the particular constraints of the situation.

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
