To find the magnitude of the normal force, you must express F_n in terms of F_w since F_f is an unknown. Using the equations you found in the two previous parts, find an expression for F_n involving F_w and theta but not F_f.
{\cos}{\theta}F_{f}-{\sin}{\theta}F _{n} =0
F_{f}{\sin}{\theta}+F_{n}{\cos}{\th eta}-F_{w} =0

Zirconium has an hcp crystal structure and a density of 6.51 g/cm3. (a) what is the volume of its unit cell in m3? (b) if the c/a ratio is 1.593, compute the values of c and a.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
