Answer:
A stripe of magnetic information that is affixed to the back of a plastic credit or debit card.
Answer:
C. Plant A orbits its star faster than Plant B
Explanation:
Did it on study island
10 minutes are the same as 600 seconds.
If you run 2 meters in 1 second then you run 2 * 600 meters in 600 seconds.
Answer:
Spiral galaxies consist of a flat, rotating disk of stars, gas and dust, and a central concentration of stars known as the bulge. These are surrounded by a much fainter halo of stars, many of which reside in globular clusters.
Elliptical galaxies have smooth, featureless light-profiles and range in shape from nearly spherical to highly flattened, and in size from hundreds of millions to over one trillion stars. In the outer regions, many stars are grouped into globular clusters. Most elliptical galaxies are composed of older, low-mass stars, with a sparse interstellar medium and minimal star formation activity They are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure. Collectively they are thought to make up about a quarter of all galaxies.
irregular galaxies were once spiral or elliptical galaxies but were deformed by gravitational action. they are shapeless.
Answer: Final temperature of a gold nugget will be 297 K
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
q = heat released = -4.85 kJ = -4850 J
m = mass of metal = 376 g
= final temperature of metal = ?
= initial temperature of metal = 398 K
c = specific heat of metal =
Thus the final temperature of a gold nugget will be 297 K
