Fundamentals of Physics 10
In Fig. 5-64, a force of magnitude 12 N is applied to a FedEx box of mass m2 " 1.0 kg. The force is directed up a plane tilted by u " 373. The box is connected by a cord to a UPS box of mass m1 " 3.0 kg on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord

Conceptual Physics 12
If you exert a horizontal force of 200 N to slide a crate across a factory floor at constant velocity, how much friction is exerted by the floor on the crate? Is the force of friction equal and oppositely directed to your 200-N push? If the force of friction isnt the reaction force to your push, what

Biochemistry 9
It is possible for the codons for a single amino acid to have the first two bases in common and to differ in the third base. Why is this experimental observation consistent with the concept of wobble?
