To move a resting box of 100 newton on the ground with kinetic friction coeficient of 0,250 is applied a force of 60 n horizontally and displacing it 10 m. how much work does applied force do? how much work is done against friction force? what is kinetic energy of the box?
none of the above, it should be kinetic.
series resistors just add.
rt = r1 + r2 + r3r1 = 5r2 = 3r4 = 8
rt = 5 + 3 + 8
rt = 16 ohms
answer : absorbs and releases thermal energy by first vaporizing then condensing.
the transfer of heat from one place to another is a function of refrigerant.
initially, the liquid refrigerant enters the indoor coil. here, it changes from liquid state to vapor state. then this vapor refrigerant enters into the compressor.
finally, it flows into the condenser. here, it releases heat to the outside air.
so, refrigerant absorbs and releases thermal energy by first vaporizing then condensing.
