A certain object is subject to two forces: a 10-N force straight up and a 10-N force straight down. A student states that since both forces are in the vertical direction, the object cannot be moving
horizontally. Why is this an incorrect conclusion?
A) The vertical forces are balanced.
B) vertical net forces can cause horizontal motion.
C) horizontal force is not required for horizontal movements.
D) two vertical forces can combine to form a horizontal motion.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
