Answer:
answer in the explanation!!
Explanation:
1: light being emitted from a light bulb is called electromagnetic waves ; transverse wave.
2: sound coming from a violin is a mechanical wave ; longitudinal wave.
3: a rock being dropped in a pond is a mechanical wave ; and im pretty sure its longitudinal and/or transverse.

There was no need to. They must have been able to survive just fine without the use of other cells
Answer:
Better Equilibrium Maintenance for better accuracy...
Explanation:
In the Galileo's experiment, there is no utilization of two equal masses at a time. However, as we can see in a Atwood Machine, there are two equal masses involved that make the whole system to be in a state of equilibrium and ultimately the better measurements of acceleration due to gravity.
Answer:
26000 years
Explanation:
Precession describes the angular motion of the Earth's body. Since the attitude of telescopes relative to the Earth's body can be controlled with high accuracy, and telescopes can measure the direction of incoming light also with high accuracy, the motion of Earth is under permanent high precision monitoring. Thus the basic numerical descriptor of precission, an angular rate of 5029.0966 seconds of arc per Julian century, traditionally denoted p (for precession) is a measured value from observed coordinate changes of thousands of stars over, say, two centuries. The understanding of this value in terms of forces acting on an oblate Earth from the Moon is well understood so that an extrapolation back and forth over a few full cycles contains little uncertainties. Of course, you can find details on the coordinate transformations mentioned above (the direct observational effect of precession) on the net. I was surprised to see that the Wikipedia article on precession covers the astronomical aspect very poorly. You thus better look for other sources.
