A model for the basal metabolism rate, in kcal/h, of a young person is R(t) = 85 − 0.17 cos πt 12 , where t is the time in hours measured from 5:00 AM. What is the total basal metabolism of this person for a 24-hour period?

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
