Answer: the four terrestrial planets must once have been hot enough to be molten (like a liquid)
Explanation: Terrestrial planets can be defined as any planet of the solar system or any exoplanet which is "Earth-like" in the sense that it is composed primarily of metals and rock, in contrast to a planet which is a gas giant.
Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars.
Scientist believing that the densest, heaviest materials are at the center and not evenly distributed can be due to the fact that they must once have been hot enough to be molten. In this case, density will take place, making the heavier under and the lighter on top.

Answer: She must study even if she has no interest in being a performer or composer.
Explanation:
If Gertrude wants to work in an area related to music because it is one of her great interests, she must study to know what is involved in the world of music. Many people have the misconception that studying music is only related to being a singer or songwriter, but in reality, it is a much more complex process. Universities offer music as a career and there are specialties where the person can decide in which area of music they want to focus on.
There are people who take the path of being singers or composers and others decide to focus on the field of logistics and management. Music companies need people who not only know about music but how to keep the business, make contracts and keep everything in order.
The world of music goes beyond simply being in an environment where sounds, melodies, and songs are heard, there are logistics and processes that lead the musical industries that many studies entail.
Gertrude must carry out studies in the area of music not only for the purpose of interest, but having good academic preparation will serve to continue growing in this area. People prepared both in theory and in practice are more likely to grow at work.
Gertrude should not see studying music as simply the purpose of being a performer or composer, music is a career and many people who are behind the scenes are trained people, with studies in the area of music.

Waiting time for a 100 Mbps broadcast channel is 0.512 ms
Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,
where K is drawn randomly. For K = 100,
The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms
The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms
Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms
Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms
<h3>
What is a collision in Ethernet?</h3>
A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time. The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them. On Ethernets, collisions are unavoidable.
<h3>
How collision is avoided in Ethernet?</h3>
A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work. Collisions entail the application of force (there is a change in velocity).
