The answer is D) second/meter
Answer: Bohr's model
Explanation:
The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.
The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.
Every particle of mass is attracted to every other particle of mass. The magnitude of the force between two objects is proportional to the product of their masses, and inversely proportional to the square of the distance between them. The direction of the force is along the line between their centers.
(NOTE: Newton's 3rd law of motion tells us that gravitational forces always come in pairs. Between two objects, there are two forces ... one in each direction. Their strengths are equal ... Your weight on Earth is exactly equal to the Earth's weight on YOU.)
The half-life of C-14 is approximately 5730 years. This means that the quantity contained in the sample becomes half of its original value after 5730 years. After another 5730 years, the quantity becomes 1/4 of its original value, and so on.
In our problem, the s<span>ample shows only one-fourth of its estimated original quantity, this means that its age is twice 5730 years:

Answer: if the heat energy is wasted, then, energy is lost forever.
Explanation: According to conservative of energy, which state that energy is neither created nor destroyed but only convert from one form to another.
The energy which should have been used in one form has been converted to heat energy which could have been used for for thing or the other, if there is nothing the heat energy can be used for, then the energy is wasted. This is tantamount to being lost forever.
