Calculate the work done if Boulder of mass 10gk is rolled 40m up slope at an angle of 20°.assumw the force of friction is negligible​

G= 0 L = my G= 0 Show that if a slab is rotating about a fixed axis perpendicular to the slab and passing through its mass center G,the angular momentum is the same when computed about any other point P. P G V 988

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.
