In the smectic A liquid-crystalline phase, . A. the molecules are aligned along their long axes, with no ordering with respect to the ends of the molecules B. the molecules are arranged in sheets, with their long axes parallel and their ends aligned as well C. the molecules are aligned with their long axes tilted with respect to a line perpendicular to the plane in which the molecules are stacked D. disk-shaped molecules are aligned through a stacking of the disks in layers E. the molecules are oriented in a totally random fashion

a is the answer to this question

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
