Weight = mass × gravitational field strength
At space gravitational field strength is very low so its"weightless".
Well i cant <span>explain it as well as i would like, if i did it would make no sens, but the answer should be (C.) 60m. but i`m only 95% sure its the answer. i hope this helps!</span>

<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
<em>✔ We have Ek = 1/2m x v² </em>
- Ek = 1/2 x 79.8 x 16²
- Ek = 10 214.4 J
In order to come to a complete stop, the cyclist must convert all his kinetic energy into thermal energy. Given that the braking force opposes movement, the work is therefore resistant, i.e. W = -10 214.4 J.
An isotope is an atom with a different number of neutrons than another atom of the same element. Since atoms of the same element all have the same number of protons, choice B(6pro &6neu vs. 6pro&7neu) is an example of isotopes
Basically, the temperature is a result of the average kinetic energy of all the atoms comprising the solid/liquid/gas. In solid, these atoms can just vibrate in place, leaving them to only be able to conduct and radiate heat. However, as you probably know liquids and solids take the shape of their container because the bonds between atoms are loose enough to allow them to freely move around. Due to each individual atom having its own energy, and these atoms being free to move about the liquid/gas they collide with other atoms in the substance. These collisions result in a transfer of energy. Finally, lower energy atoms "sink" and higher energy atoms "rise" thus creating a "convection current".
