ENERGY or gravity, also u could do a roller coaster thats shows gravity and energy
Una reacción química, también llamada cambio químico o fenómeno químico, es todo proceso termodinámico en el cual dos o más especies químicas o sustancias (llamadas reactantes o reactivos), se transforman, cambiando su estructura molecular y sus enlaces, en otras sustancias llamadas productos.
Answer:
a structural variation in which different atoms of the same element have different numbers of neutrons
Explanation:
An isotope is an atom of an element having the same number of protons but different number of neutrons. Different isotopes are used for different purposes. Example: some are used in medicines , food irradiation, etc.
Carbon has three isotopes C 12, C 13, C 14. All three of them have 6 protons but have different numbers of neutrons.
C 12 is a common element and is abundant in nature
C 13 is less abundant than C 12
C 14 is used for dating fossils . It is radioactive
<span>The weight lifted by a machine to the applied force on a machine is called mechanical advantage.
This is written as Mechanical advantage, M. A, = load(weight)/effort.
So for 1) M.A = 2 and load = 2, 000lb = 8896.446N.
So 2 = 8896.446/ effort
Effort = 8896.446/2 = 4448.48
Similarly for M.A of 2, 000, 000 we have
Effort = 8896.446/ 2, 000, 000 = 0.004448</span>
Russian nesting dolls are an amazing comparison for the strongest magnet in the world, because the magnitis were inserted inside each other. The magnets would be adapted so they could be put together, Because they are closer, the coils of the magnet would be tougher. The magnets would be able to magnetize better.
