Lemonade is a conductor, because most liquids are conductors
When the tuning forks are struck simultaneously, the beat frequency is equal to the absolute value of the difference between the frequencies of the two tuning forks:
where
is the beat frequency, and
are the frequencies of the two forks.
In the first part of the problem,
and
, with
being the frequency of the unknown fork. In the second part of the problem,
and
. So we have the following system of two equations:
and the solution of this system is
Answer:
A rocket with more mass will speed up more slowly, just as in the horizontal example, but there is another effect. The force of gravity is now acting in the opposite direction to the thrust, so the resultant force pushing the rocket upwards is also less.
Explanation:
Because tropical moist forests are used for agricultural, the thin soil cannot support continuous cropping, while deciduous forests can regrow quickly.
<span><span>-When sunlight strikes a falling drop of water it is refracted, changed indirection, by the surface of the water.</span>
The light continues into the drop and is reflected from the back of the drop to the front. When the beam hits the front it is refracted again and emerges from the drop as the color spectrum that we see in a rainbow.<span>-The water drop acts like a prism to seperate the light into its different wave lengths.</span></span>
