Answer:
If the speed of the merry-go-round doubles, the force you will need to exert to hang on is 400 N.
Explanation:
Given;
initial force exerted to hang on, F₁ = 100 N
The force exerted on the merry-go-round in order to hang on must be an inward force known as centripetal force.
Centripetal force is given by;
![F_c = \frac{mv^2}{r} \\\\keeping \ "m" \ and \ "r" \ constant, we \ will \ have \ the \ following \ equation;\\\\\frac{F_c_1}{v_1^2} = \frac{F_c_2}{v_2^2} \\\\F_c_2 = \frac{F_c_1*v_2^2}{v_1^2}\\\\when \ the \ speed\ doubles \ i.e, v_2 = 2v_1\\\\ F_c_2 = \frac{F_c_1*(2v_1)^2}{v_1^2}\\\\ F_c_2 = \frac{F_c_1*4v_1^2}{v_1^2}\\\\F_c_2 = F_c_1 *4\\\\F_c_2 = 4(F_c_1)\\\\F_c_2 = 4 (100 \ N)\\\\F_c_2 = 400 \ N](https://tex.z-dn.net/?f=F_c%20%3D%20%5Cfrac%7Bmv%5E2%7D%7Br%7D%20%5C%5C%5C%5Ckeeping%20%5C%20%22m%22%20%5C%20and%20%5C%20%22r%22%20%5C%20constant%2C%20we%20%5C%20will%20%5C%20have%20%5C%20the%20%5C%20following%20%5C%20equation%3B%5C%5C%5C%5C%5Cfrac%7BF_c_1%7D%7Bv_1%5E2%7D%20%3D%20%5Cfrac%7BF_c_2%7D%7Bv_2%5E2%7D%20%5C%5C%5C%5CF_c_2%20%3D%20%5Cfrac%7BF_c_1%2Av_2%5E2%7D%7Bv_1%5E2%7D%5C%5C%5C%5Cwhen%20%5C%20the%20%5C%20speed%5C%20doubles%20%5C%20i.e%2C%20v_2%20%3D%202v_1%5C%5C%5C%5C%20F_c_2%20%3D%20%5Cfrac%7BF_c_1%2A%282v_1%29%5E2%7D%7Bv_1%5E2%7D%5C%5C%5C%5C%20F_c_2%20%3D%20%5Cfrac%7BF_c_1%2A4v_1%5E2%7D%7Bv_1%5E2%7D%5C%5C%5C%5CF_c_2%20%3D%20F_c_1%20%2A4%5C%5C%5C%5CF_c_2%20%3D%204%28F_c_1%29%5C%5C%5C%5CF_c_2%20%3D%204%20%28100%20%5C%20N%29%5C%5C%5C%5CF_c_2%20%3D%20400%20%5C%20N)
Therefore, If the speed of the merry-go-round doubles, the force you will need to exert to hang on is 400 N.
We can get water from the sweat and exhaled breath of the people present in the space station.
<h3>How would you get water?</h3>
We can get water from the sweat and exhaled breath. The water we drink is recycled from the sweat and exhaled breath of the people present in the space station which was collected through condensation on the Space Station's walls.
So we can conclude we can get water from the sweat and exhaled breath of the people present in the space station.
