Break into small particles. The heat causes the rock to break up and form pebbles or sand. Hope that helped. Have a nice day
The most likely answer will be B. Overfishing is still a large issue today, and it can really ruin a habitat. =)
Answer:
67.6 m
Explanation:
For this problem, we just need to analyze the motion of the two planes after the collision.
The two planes stick together and move with a velocity of
u = 19.3 m/s
The problem tells us that they skid until they stop: so, their final velocity is
v = 0
Since the velocity is not constant, this means that they are accelerating.
We also know that they skid for a time of
t = 7 s
Therefore, we can find their stopping distance using the following suvat equation

And substituting, we find

Don’t know sorry I’m just trying not a good person
Answer:
C. The number of protons.
Explanation:
All atoms of mercury will remain the same while different isotopes may have different number of neutrons.
For example, mercury has 80 protons, correlating with its atomic number. However, the number of protons, neutrons, and electrons could vary between each atom. If there are 80 protons, then there has to be 80 electrons. This means that the protons have to be the same in order to apply to all atoms of mercury
