Answer:
glucose ,fructose, sucrose,maltose,lactose etc... are some types of sugar.
These answers are very good. I made a 95% by using this as my answer key, but unfortunately, one of these is wrong. I don't know which one, all I know is that I got 19/20. Just wanted to throw that out there. :-) Good job, Sadaqasalaam3. And thank you.
Answer:
4.0 cm
Explanation:
For the compression of the spring, the kinetic energy of the mass equals the elastic potential energy of the spring.
So, 1/2mv² = 1/2kx² ⇒ x = (√m/k)v
Since m and k are constant since its the same spring x ∝ v
If our speed is now v₁ = 2v, our compression is x₁
x₁ = (√m/k)v₁ = (√m/k)2v = 2(√m/k)v = 2x
x₁ = 2x
Since x = 2.0 cm, our compression for speed = 2v is
x₁ = 2(2.0) = 4.0 cm
