Which of the following symbols represent a battery circuit with two cells wired 4 points in parallel? (Physics)

divide the right side by the left side

0.024÷1.2=0.02 for example

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
