10. A safe place to use the trebuchet would be away from other buildings and people. A good example of a place would be a large field with no nearby structures. 
14. Many factors need to be kept consistent throughout the experiment. One example of a variable that would need to be consistent is the weight and size of the projectile. 
15. It is important to do many trials so that you can make sure that the results of each trial are nearly the same. If they are all vastly different, then it means that something has gone wrong. 

Sorry I was only able to answer a few questions, but I hope these few answers help! :)

At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) (A) 0.39
exis [7]

Explanation:

It is given that,

Relativistic Mass of the stone, m₀ = 0.6

Mass, m=0.76\ kg

Relativistic mass is given by :

m=\dfrac{m_o}{\sqrt{1-\dfrac{v^2}{c^2}}}.........(1)

Where

c is the speed of light

On rearranging equation (1) we get :

v^2=c^2(1-(\dfrac{m_o}{m})^2)

v=c\sqrt{ (1-(\dfrac{m_o}{m})^2)}

v=c\sqrt{ (1-(\dfrac{0.6}{0.76})^2)}

v = 0.61378 c

or

v = 0.6138 c

So, the correct option is (c). Hence, this is the required solution.

Fission and fusion reactions both involve making changes to an atom's _____.
spayn [35]

Option (A) is correct. Fission and fusion reactions both involve making changes to an atom's nuclei.

Nuclear fission is a process in which a bigger nucleus breaks into two or more smaller nuclei with the liberation of large amount of energy.

Nuclear fusion is a process in which two smaller nuclei fuse together to form a bigger nucleus. A tremendous amount of energy is released during fusion.

Thus both fission and fusion involve the changes in the nuclei of atoms. Rest of the atom like the electronic configuration etc remains same.
