Answer:

appears to be moving back toward unmanned exploration in the form of deep-space satellite exploration.

Explanation:

NASA moved from unmanned probing of space in its initial stage of space exploration to manned space exploration and moon landing and now has gone back to unmanned exploration into deeper space. Deep space is not completely known yet, and the exploration take year and are probably very dangerous for manned exploration for now.

Laser fusion Group of answer choices uses chemical reactions to produce energy uses nuclear reactions to produce energy implodes
KonstantinChe [14]

Answer:

Uses nuclear reactions to produce energy

Implodes a fuel pellet

Explanation:

Laser fusion is a method of initiating nuclear fusion reactions through heating, and compressing fuel pellets containing deuterium and tritium using high energy density laser beams. Lase fusion is also known as inertial confinement fusion and the energy produced by the process is known as Laser Inertial Fusion Energy, LIFE.

During the process of laser fusion, small pellets of deuterium-tritium (DT) isotopes mixture are fed into a blast chamber where they are compressed to high densities using a number of amplified laser beams in the chamber.

The high energy density of the beams as well as the heat produced due to compression, induces the thermonuclear explosion ignition resulting in the production of high energetic products such as charged particles, x-rays and neutrons. The energy produced is absorbed and stored as heat in a blanket that is then used in a steam thermal cycle to generate electrical power.

There are two methods of compression of the DT pellet: direct and indirect-drive laser fusions.

However, there are a number of limitations to energy production by this process. One limitation is that the process is extremely inefficient in energy energy production. Also, the heat produced by the flashtubes results innthe deformation of the laser glass.

If the formula for a compound is represented by X3Y2 and the charge on the Y ion is -3, what is the charge in the X ion?
artcher [175]
I cannot fully remember but the charge of a compound always has to be the same.  However, I believe that the sign of the Y2 means that it is positive 2. 

so in my opinion it is in between b and c. use your best judgment.

How many elements and atoms are in marble
DochEvi [55]

Answer:

Explanation:

Scientists know that there are 6x1023 molecules in a mole - so we have about 0.5x1023 molecules in our marble…and since every silicon dioxide molecule has one atom of silicon and two of oxygen, we have a grand total of 1.5x1023 atoms. That's 150,000,000,000,000,000,000,000 atoms
