Answer:
Frying an Egg
Explanation:
When chemical bonds are broken or formed, new particles are created. Therefore, frying an egg is a chemical change because it results in the formation of new particles.
a) Proton-proton: high repulsive electrostatic, very high attractive nuclear force. Proton-neutron: no electrostatic forces since neutrons are not charge carriers, high attractive nuclear force. Neutron-neutron: no electrostatic force for the same reason and huge attractive nuclear force.
b) There are two types of forces in the nuclei: repulsive electrostatic and attractive nuclear. Nuclear act between all nucleons, electrostatic only between protons. To make a nucleus stronger, increase number of attractive forces by increasing amount of neutrons.
c) Cause due to equivalence between mass and energy E=mc^2 change in energy (which happens in nuclear reaction) causes on change in mass. Starting mass just converts to energy, that's why it's greater than the ending mass.
Answer:
-Relative refractive index– It is the ratio of speed of light in one medium to the speed of light in another medium
-Absolute refractive index– It is the ratio of light in vacuum to the speed of light in another medium.

Answer:
Digestive system
Explanation:
ulcer affect anywhere in the digestive system
The answer is D. Either absorbed or reflected. The reason is because if no light is being shown on the other side, the substance is not letting any light pass through. Since we do not know anything else about the substance, we do not know which one of the two it is doing. The scientist would not see any light on the detector if 100% of the light is reflected and the same thing would happen if 100% of the light was absorbed.
