Answer:
Explanation:
A)
W = work done by the freezer = 800 J
Q = heat removed from the freezer = 1735 J
Q' = Heat expelled into the room
Coefficient of performance is given as
inserting the values
B)
Heat expelled is given as
Q' = W + Q
Q' = 800 + 1735
Q' = 2535 J
Lol i think i had the same worksheet!! lol anyway look up newtons first law and it will be pretty self explanatory from there
Answer:
This material exhibits paramagnetism.
Explanation:
A paramagnetic material has these features: It doesn’t have any magnetic properties when placed in an external magnetic field, it gains and then loses the magnetic property as the external field is removed.
Such materials have magnetic moments oriented in random directions, thus making the net magnetic moment, zero. But when placed in an external field, they do possess a net magnetic moment. When the magnetic field is removed, they lose the magnetic property.
Thus, the material which produces no initial magnetic field when placed in a uniform magnetic field produces an additional internal magnetic field parallel to the original field. Also, it loses the magnetic properties as soon as the external magnetic field is removed. Then, the magnetism the material exhibits is paramagnetic.
