30kg chicken feed box is resting on an inclined plane. The reaction (R) normal to the plane is 275N. How much force would be required to move the box up the inclined plane?

Ithink the answer is fusion 

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
