Answer:
B and C
Explanation:
The given symbol [tex]_{-1}^{0}e[/tex] denotes an electron. An electrons has neglecting mass and has one unit of negative charge. Thus, option A is correct.
What is an electrons?An electron is a subatomic particle. the other subatomic particles that constitutes an atom are neutrons and protons. neutrons and protons are located inside the nucleus and electrons are revolving around the nucleus through circular paths of fixed energies.
Electrons are having negative charge and protons are positively charged particles. For an atom the number of protons and electrons are the same. Therefore, an element in its atomic state is neutral.
Neutrons are neutral. However both neutrons and protons are having significant mass compared to an electrons. Hence, the representation of electrons include zero mass and -1 charge. Hence, option A is correct.

Explanation:
If 400 joules of heat are added to a gas in an isochoric process, what is the
change in its internal energy?
O A. 400 J
O B.-400 J
O C. 100 J
OD. 200
Answer:
A. 400 J
Explanation:
Because the process is isochoric, no volume change, so no work, so none of the energy is lost or converted. In other words, the system will gain and hold onto all of the J of heat put into it, which was 400J
