Protons and neutrons are held together inside the nucleus.
Explanation:
The strongest force in the universe is the nuclear forces holding the neuclons together in an atom.
This force is referred to as the strong nuclear forces. It is by far stronger than electromagnetic forces.
Nuclear forces are stronger than chemical binding forces which is seen between two particles attracting one another via static electricity.
It stronger than the gravitational force experienced by two equal masses that falls to the ground at the same speed.

Answer:
B. positive; negative.
Explanation:
From the viewpoint of Principle of Energy Conservation and Work-Energy Theorem, we notice that gravity represents a conservative force, associated with gravitational potential energy, whereas air resistance is a non-conservative force, associated with dissipated work. Therefore, the work done by gravity is positive and work done by air resistance is negative. Therefore, the correct answer is B.
By having no solid matter between the walls (like styrofoam) conduction is eliminated since conduction requires matter to be in contact with other matter. The vacuum state eliminates convection since that is the heating of gas that then carries the energy to another body by traveling there and exchanging heat with it.
On a hot dry day, the amount of water vapour present in atmosphere is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. Hence, a desert cooler cools better on a hot dry day.
The answer will be 0.90 speed
