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?

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
