i posted this earlier, but no one answered. so i'll try again. Can you check my work please? true/false 1.) force is a scalar quantity: *FALSE 2.) the object on which a force acts is called the system: *TRUE 3.)The specific, indentifiable cause of a force is called the sys...
PHYSICS ~so confused~
so i'm going to try my hardest to type this out. which of the following system of forces provides the block the highest net force? a.) 11N--->[box]<---71N b.) 405N--->[box]<---403N c.) 227N--->[box]<---153N d.) 22.7N--->[box]<---15.3N I thought this...
