Calculate the power produced by a 12 V battery charger if it delivers:A. 10 A in the fast charge modeB. 2 A in trickle charge mo
1 answer:
The electric power (P) produced by an electric current (I) passing through a voltage (V) is given by the equation:
If the battery charger works with a voltage of 12V, replace V = 12V into the equation, as well as the corresponding values for the electric current to find the power produced in each case.
A) I = 10A
Replace V=12V and I=10A to find the power produced in the fast charge mode:
B) Replace V=12V and I=2A to find the power produced in the trickle charge mode:
Therefore, the power produced by a 12V battery charger is equal to 120 Watts when it delivers 10A in fast charge mode, and 24 Watts when it delivers 2A in trickle charge mode.

Answer:
Final displacement with respect to the starting position is 832.37 meter
Explanation:
Lets consider that the orienteer start to run on the point of (0,0) point of a coordinate system. When he runs towards to east side about 400m, he will be at the point A(400,0). After he runs to the northeast (at a 45 degree angle from due east and from due north), approximately he will make 353.55 meter to east and 353.55 meter to the north side and he will be at the point of B(753.55, 353.55)
From the starting point total displacement will be 832.37 meter. Please check the attached graphical solution.
