Test yourself 3: Two forces of 60 N and 80 N respectively act simultaneously at a point.
Sketch and determine their resultant by using the following methods:
a) tail-to-head
b) tail-to-tail (122 N 25°)​

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
