The gravitational acceleration on the moon is about one-sixth the size of the gravitational acceleration on Earth. According to Newton’s second law of motion, what happens to an astronaut who goes to the moon? A. The astronaut’s weight decreases because the moon’s gravitational acceleration is greater than Earth’s.
B. The astronaut’s weight increases because the moon’s gravitational acceleration is greater than Earth’s.
C. The astronaut’s weight decreases because the moon’s gravitational acceleration is less than Earth’s.
D. The astronaut’s weight increases because the moon’s gravitational acceleration is less than Earth’s.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
