Answer:
stryo: 1
wood: 1
ice: 1
brick: 2
aluminum: 2.7
Explanation:
d= mass/ total volume
(fyi: for aluminum, they did the subtraction wrong to find the total volume. it is actually 5 or 5.00)
The major difference is: Mercury has no orbiting satellites, while Jupiter has many satellites that surround it, so the correct answer is C
Hydrogen is the original fuel that keeps a star "burning" by nuclear fusion.
No hydrogen and the star will die unless it can start use helium to produce energy.
Hiya!
An ecosystem is an entire community of living things. They have life cycles, breathe, eat, etc., and all interact with one another. Non-living things, like rocks are dirt, are also a part of an ecosystem. Everything lives in one!
Unfortunately, humans can harm the ecosystem. Fossil fuels, non-renewable resources like coal and oil, killing of animals, and dumping toxic waste can and does harm the ecosystem.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
At this point in the story, Beasy has driven his car (2+6+4) = 12 km.
He is parked at the thrift store, (2+4) = 6 km East and 6 km North of his starting point.
As the crow flies, the thrift store is √(6km² + 6km²) in a straight line from the starting point.
That's √(72 km²) , which works out to 8.485 km . When rounded to the nearest whole km, he can phone up his wife and tell her he's "eight kilometers from home can you hear me now ?".
Displacement is a vector, so to answer the question completely, we also need to state its direction.
The angle from home to the thrift store, relative to East, is arctan(6km/6km).
That's 45 degrees.
The full displacement vector is <em>8.485 km Northeast.</em>
