The electric fields at the points (5.0 cm, 0 cm), (-5.0 cm, 0 cm), and (0 cm, 5.0 cm) due to a -12 nC charge are -67.5x10^3 i^ N/C, 30x10^3 i^ N/C and -67.5x10^3 j^ N/C respectively.
The subject of this question is Electric Field, a part of physics. Specifically, we're looking at point charges and using the formula for the electric field due to a point charge, which is E = k|Q|/r², where k is the Coulomb's constant, Q is the charge and r is the distance to the point where the electric field is calculated.

B. A warm and dry day with a wind moving in the opposite direction as the sound
C. A cold and dry day with a wind moving in the same direction as the sound
D. A cold and humid day with no wind
The answer is A. A warm and humid day with a wind moving in the same direction as the sound. hope this helps!!!!
The correct statement is: An atomic nucleus contains most of the atom’s mass.
All of the atom's neutrons and protons are in the nucleus, and the atom's electrons are outside the nucleus.
It would take more than 1,800 electrons to add up to the mass of one neutron or one proton.
But no atom has more than around 240 electrons, so we can see that almost all of the atom's mass is in the nucleus.
The atomic nucleus is best described as containing most of the atom's mass due to the presence of protons and neutrons, not as being negatively charged or mostly empty space.
The correct statement that describes an atomic nucleus is that an atomic nucleus contains most of the atom’s mass. This is due to the presence of protons and neutrons in the nucleus which carry nearly all the mass of the atom. The nucleus is not negatively charged, it carries a positive electric charge because of the protons. It is also not correct to say that it's mostly empty space as this describes the whole atom's structure where most of the space is taken up by electrons circling the nucleus.

Answer:
Mechanical energy is divided into two:Kinetic energy and Potential energy....The diver diving down exhibits kinetic energy because she is moving but when she has stopped it means she has potential energy which means that a body is at rest....
Answer:
Energy cant be created or lost, it only changes form.
Explanation:
The answer above is correct.
