a) 3.51
b) 7.5
c) 4.84
d) 3.34

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

In an experiment, how can i change human errors? be specific.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
