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
Easy brother. You just need some luck.
Inside every black hole is a time machine that allows you to turn back time or go forward and teleport to any empty space in the universe. However to do so you need to get inside the black hole without dieing.
To do so you must make the hardest and lightest box you can make, fill it with a very dense kind of air that will allow you to breathe but not move. Then seal yourself In the box.
Get someone to throw you in the black hole. And if you come back alive give me a Brainliest answer ;)

Answer and Explanation:
The answer is <u>D) Alpha and Gamma</u>
Gamma radiation does not cause transmutations.
A <u>transmutation</u> is the <u>conversion of an atom of one element to an atom of another. This generally occurs through nuclear reacting.</u>
There are three main types of radiation: alpha, beta, and gamma. Both beta and alpha decay cause changes to the mass and atomic numbers. This results in a transmutation. Gamma radiation, however, does not.
Gamma radiation is the result of a gamma ray. In essence, the nucleus emits a high-energy proton. This is very penetrating and can only be stopped by aluminum, lead, soil, water, and concrete. This type of radiation does not change the element and, therefore, does not cause a transmutation.
