The ball will hit with a force of 56 newtons per second
Lunar maria (plural form of the Latin word mare, which means sea) are
dark surfaces that can be found all over the moon (17% of the Moon is
covered in them) that have been created as a result of volcanic
eruptions. These areas are made up of basalt, and given that they seemed
almost waterlike, the astronomers in the distant past mistook them for
seas, whence their name comes.
When it comes to craters, their origin
is quite similar - volcanic eruptions created them. When lava starts
erupting from a volcano, it has to get out from somewhere - and thus
craters are created. If you are referring to lunar craters, however,
there are many speculations as to how they were created: due to volcanic
eruptions, meteoric impact, or glacier activity.
C. Accelerating upward
Has to do with Newtons 2nd law of motion.
F=MxA. Mass times acceleration
So acceleration upwards the scale is pushing back on your normal weight plus your mass and the acceleration rate of the elevator car.
The opposite occurs when descending.
If at a constant speed/velocity, equilibrium occurs and weight exerted by ones body stays the same.
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.
