The three branches of science are life, earth, and physical science.
Life science deals with living organisms, so, biology is the most important of these sciences, although there are many.
Earth science deals with Planet Earth, studying its atmosphere, lithosphere, etc.
Physical science studies the inorganic world.
The kinetic energy is given by:
![K=\frac{1}{2}mv^2](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
We know the mass and the maximum speed, plugging their values in the expression above we have:
![\begin{gathered} K=\frac{1}{2}(9.1\times10^{-31})(8\times10^6)^2 \\ K=2.91\times10^{-17}\text{ J} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20K%3D%5Cfrac%7B1%7D%7B2%7D%289.1%5Ctimes10%5E%7B-31%7D%29%288%5Ctimes10%5E6%29%5E2%20%5C%5C%20K%3D2.91%5Ctimes10%5E%7B-17%7D%5Ctext%7B%20J%7D%20%5Cend%7Bgathered%7D)
Therefore, the answer is d.
Answer:
Explanation:
Unbalanced forces will result in the presence of acceleration. The formula
F net = ma
says that if there is a net force present and the object in question has a mass, then an acceleration is present. Now acceleration is constant in this situation because nowhere does it say the acceleration is changing. If acceleration is constant then the velocity is increasing at a steady pace (think linear function!).
The direction of the object depends on the direction that the net force is in. If the net force is to the left, then that object will accelerate to the left.
Hope this helps :)
The answer would be B, George Darwin :)
