Explanation:
Let the spring constant of two springs are k₁ and k₂. In series combination of springs, the equivalent of springs is given by :
![k_{eff}=\dfrac{1}{\dfrac{1}{k_1}+\dfrac{1}{k_2}}](https://tex.z-dn.net/?f=k_%7Beff%7D%3D%5Cdfrac%7B1%7D%7B%5Cdfrac%7B1%7D%7Bk_1%7D%2B%5Cdfrac%7B1%7D%7Bk_2%7D%7D)
So, if it is required to swap out a single spring for the two springs that are in series, the spring constant need to be to generate the same force at any displacement is,
![\dfrac{1}{\dfrac{1}{k_1}+\dfrac{1}{k_2}}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B%5Cdfrac%7B1%7D%7Bk_1%7D%2B%5Cdfrac%7B1%7D%7Bk_2%7D%7D)
Hence, this is the required solution.
Answer:
Saturated fats/ solid fats
Explanation:
Vegetable oils amongst other unsaturated oils are liquids at room temperature while saturated oils are solids or spreadable at room temperature.
Industrially, vegetable oils are hydrogenated; hydrogenation is the process of adding hydrogen to an unsaturated compound to make it saturated. This then makes these hydrogenated vegetable oil, saturated which makes them solids as earlier stated, they are also called cis - fatty acids.
Trans - fatty acids as well are also unsaturated oils which are hydrogenated industrially to give saturated fatty acids which are called artificial tran-fats. They are found in most commonly found in baked and fried goods.
