Answer:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
Because most of the volume of an atom is where the electrons move.
Rachel Carson was an American marine biologist, who after the discovery of the effects of synthetic pesticides on the environment, became a conservationist.. She wrote a book called, <em>Silent Spring</em> which helped advance the worldwide environmental movement. Her book, <em>Silent Spring</em> expressed her feelings and thoughts on the environmental problems, including many problems with synthetic pesticides like DDT. <em />This then influenced a nationwide ban on many pesticides, including DDT. Her book lead to the inspiration of the grassroots movement and the creation of the U.S Environmental Protection Agency. Rachel Carson was also awarded the Presidential Medal of Freedom by Jimmy Carter.
We know, 1 m/s = 3.6 Km/h
So, 45 Km/h = 45/3.6 = 12.5 m/s
In short, It would be equal to 12.5 m/s
Hope this helps!

because Matthias Schleiden found that all plants are composed of cells, and communicated the finding to Schwann, who had found similar structures in the cells. Other researchers confirmed the similarity, as explained in his book, where he concluded, "All living things are composed of cells and cell products.
This became the cell theory.
I learn that in my old school.
