Answer:
200 N
Explanation:
The crowbar is 2 meter, or 200 cm. The effort arm is 160 cm, so the moment arm of the object is 40 cm.
(800 N) (40 cm) = F (160 cm)
F = 200 N
Do you have multiple choice answers? the lower layers are generally older than the higher layers.
Field motion ( as opposed to collision motion) which are forces like gravity. And Static motion ( as opposed to kinetic motion)
