I would say B. A stable home and varied activities
When conducting and experiment you want to have a notebook and something to write down notes with so you can keep everything organized and proper, and to not miss anything in the experiment. Also you want to have everything in order of the way it should be in.
I hope you found this helpful!
Answer:
F = 2.668*10_-6[N]
Explanation:
We can calculate this force using the law of universal gravitation raised by Isaac Newton
![m_{t}=20000[kg]\\m_{c}= 200[kg]\\r = 10[m]\\G = 6.67*10^{-11}[\frac{N*m^{2} }{kg} ] \\](https://tex.z-dn.net/?f=m_%7Bt%7D%3D20000%5Bkg%5D%5C%5Cm_%7Bc%7D%3D%20200%5Bkg%5D%5C%5Cr%20%3D%2010%5Bm%5D%5C%5CG%20%3D%206.67%2A10%5E%7B-11%7D%5B%5Cfrac%7BN%2Am%5E%7B2%7D%20%7D%7Bkg%7D%20%5D%20%5C%5C)
And the force is given by the following expression:
![F=G*\frac{m_{t}*m_{c}}{r^{2} } \\F=6.67*10^{-11} *\frac{20000*200}{10^{2} }\\F=2.668*10^{-6} [N]](https://tex.z-dn.net/?f=F%3DG%2A%5Cfrac%7Bm_%7Bt%7D%2Am_%7Bc%7D%7D%7Br%5E%7B2%7D%20%7D%20%5C%5CF%3D6.67%2A10%5E%7B-11%7D%20%2A%5Cfrac%7B20000%2A200%7D%7B10%5E%7B2%7D%20%7D%5C%5CF%3D2.668%2A10%5E%7B-6%7D%20%5BN%5D)
Answer: B. It is directed to the left.
Explanation:
Gravitational force is an attractive force, this is stated by Newton's law of Gravitation:
<em>"The force exerted between two bodies of masses m1 and m2 and separated by a distance is equal to the product of their masses and inversely proportional to the square of the distance"</em>
This means both m1 and m2 are mutually attracted.
Hence, if the force exerted on m1 by m2 is directed to the right, the force exerted on m2 by m1 must be logically <u>directed to the left.</u>
