The answer should be c....
Answer:
The answer is <em>15A</em>
Explanation:
Terminal of like polarity are connected with jumpers of negligible resistance
Kirchoff's voltage law gives
E1 -E2 - IR1 - IR2 = 0
I(R1 + R20 = E1 -E2
I= 12 -9/ 0.18 + O.2 = 15A OF CURRENT WILL FLOW THROUGH DISCHARGED BATTERY.
Electroreception is limited to aquatic environments because on here is the resistivity of the medium is low enough for electric currents to be generated as the result of electric fields of biological origin. In air, the resistivity of the environment is so high that electric fields from biological sources do not generate a significant electric current. Electroreceptor are found in a number of species of fish, and in at least one species of mammal, the Duck-Billed platypus.
Answer:
double
Explanation:
According to the newton's second law
force = mass x acceleration
So, acceleration is directly proportional to the force.
As the force is doubles, the acceleration is also doubled.
Spiral galaxies are still undergoing star formation
