Answer:
A substance made of two or more types of atoms
Explanation:
The speed of the ball just before impact was v=√(2gh) = 6.26m/s. The acceleration is twice this over the time (twice because the second speed is the same in the other direction, meaning the total change in speed is 2V)
a = 12.52/0.10 = 125.2m/s²
The force is F=ma, so F = 0.5kg·125.2m/s² = 62.6N
Answer:
B. climate change
Explanation:
asteroids are too big and volaconos are probably gonna create a lot of smoke that can kill ya in seconds so I guess climate change
It won't be able to mix because one will not get evaporated and it wont go together
The heat capacity is given by the expression:
When the 
is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in 
, we can then determine the specific heat "C" by simply remplazing in the expression.
