Answer:
a planet
Explanation:
If planetesimals, objects that combined to form protoplanets, were to collide head on in the early solar nebula, they would shatter to the point where they would be unable to grow into a larger size, a protoplanet. A protoplanet is a massive object that will eventually become a planet.
Answer: 1: kinetic energy and velocity are at zero when the magnets are held apart, and both increases rapidly when they are released and move together. Energy stored in the magnetic field decreases.
2: The energy stored in the system is converted to kinetic, thermal, and sound energy.
3: The energy stored in the magnetic field does not change.
4: Some of the energy stored is converted into kinetic and thermal energy.
5: Two small repelling magnets hold each other in place.
Just took the quiz all are correct! I hope this helps you! :)
"Venus" has all that characteristics. It has <span>a rocky mantle, iron core and very dense atmosphere that is 96.5% poisonous carbon dioxide and 3.5% nitrogen
In short, Your Answer would be "Venus"
Hope this helps!</span>
Answer:
8 km an hour (about 5mph)
Explanation:
It depends on what you are looking for because there is no unit specified, but if you want kilometers an hour then all you have to do is multiply both sides by 2.
30 x 2 = 60 (minutes)
4 x 2 = 8 (kilometers)
Hope this helped at least a little bit!
Answer:
v = 771.75 mile / h
Explanation:
The speed of sound is v = 343 m / s at T= 20C
the transformation ratios are
1 mile = 1600 m
1 h = 3600 s
Let's reduce
v = 343 m / s (1 mile / 1600 m) (3600 s / 1 h)
v = 771.75 mile / h
