dependent variables
Explanation:
dependent varibeles are the thing you're measuring and independent variables are the thing you change in the exeriment to get a different dependent variable.
may I get brainliest please? :)
Answer:

Explanation:
As we know that here final equilibrium temperature is 0 degree C
so we can use energy conservation here
heat given by the cube = heat absorbed by the ice
so we have

so here we have



Using the second Law of Newton, F = m * a, you know that acceleration is maximum when the force is maximum.
Using Hooke's Law, F = K Δx, you know that the force is maximum when the displacement from the equilibrium (Δx) is maximum.
So the answer is that the acceleration is maximum at the maximum amplitude x = a.
Answer:
7 meters per second or 7 m/s
