Nthe movie for this pre-session, we go through a calculation in which the force applied on a solar sail by radiation pressure from sunlight is 0.1 n, with the solar sail having a mass of 500 kg. there was a complication, however, that the sail also experienced a gravitational force, attracting it toward the sun. let's say you re-design the solar sail, giving it a larger sail area, so that the net force on the solar sail is 0.1 n, directed away from the sun, and you manage to keep the mass at 500 kg. the magnitude of the solar sail's acceleration is 0.0002 m/s^2.
let's assume that the solar sail starts from rest, and then has this same acceleration for the next 18 days.
(b) what is the speed of the sail after 18 days?
m/s
(c) how far has the sail traveled in the 18 days?
m

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
