Answer:
the answer is that the dough has the same mass before and after it was flattened
Answer: Change in velocity: -10 m/s, acceleration=-2.5m/s
Explanation:
The question in english is written below:
The end of a robotic arm moves to the right at 8m s. Four seconds later it moves to the left at 2m/s. What is its change in velocity and what is its change in acceleration?
We have the following data:
Initial Velocity of the robotic arm: (to the right)
Final Velocity of the robotic arm: (to the left)
Variation in time:
Firstly we have to calculate the change in velocity , which is given by the following equation:
This means the resultant velocity is to the left
Now, we can find the acceleration , given by:
This means the acceleration is also to the left, however its magnitude is always positive:
Answer:
Is fire matter? Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter.

2. Metamorphic rock
4. Igneous rock
Umm I’m not 100% sure because I learned all this back in 5th grade and I can’t really remember. But this is what I think I know.
Also for your 2nd question I don’t really know
