Gravitational Potential energy is the energy stored with regard to position.
the equation for potential energy is as follows
P.E = mass x gravitational acceleration x height from the ground
gravitational acceleration - 9.8 ms⁻²
substituting the values in the equation
P.E = 125 kg x 9.8 ms⁻² x 1500 m
P.E = 1 837 500 J
therefore the potential energy of the diver at 1500 m high is 1 837 kJ
The answer should be D) Earth or the fourth option.
Answer:
a little less than 6 micrograms
Explanation:
The half-life of an element is defined as the time in which half of the isotope emits its radiation and becomes a different element. Therefore after 4.5 billion years the meteoroid will contain 12 micrograms of uranium, after 9 billion years will contain 6 micrograms. After 10 billion years will contain a little less than 6 micrograms.
The correct answer is
1
Potassium has 1 valence electron. In fact, it is in the same group of sodium in the periodic table. But sodium has 1 valence electron, since it is in the 11th position, because the first two elements of the periodic table fills the first orbital, while the elements from 3 to 10 fill the second orbital (made of 8 electrons), so the 11th element (sodium) has 1 valence electron.
Description:
As we know that the sun offers what most of the world has to go examples could be energy, air. As we also know that heating causes liquid and water that is frozen to evaporate to water vapour gas. Meaning the sun provides the energy necessary for evaporation.
