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.
Answer:
convection
Explanation:
By the actual movement of molecules
Answer:
at point F
Explanation:
To know the point in which the pendulum has the greatest potential energy you can assume that the zero reference of the gravitational energy (it is mandatory to define it) is at the bottom of the pendulum.
Then, when the pendulum reaches it maximum height in its motion the gravitational potential energy is
U = mgh
m: mass of the pendulum
g: gravitational constant
The greatest value is obtained when the pendulum reaches y=h
Furthermore, at this point the pendulum stops to come back in ts motion and then the speed is zero, and so, the kinetic energy (K=1/mv^2=0).
A) answer, at point F
