A family made the observation that more expensive brands of popcorn seem to produce Discovery Education
more popped kernels than cheaper brands of popcorn. In order to test this hypothesis,
the family conducted an experiment in which they followed the procedures below:
•
The family bought 2 differing brands of popcorn to test: Wilbur Bockenreder Popcorn
and PopWhisper.
•
They measured 1 cup of kernels and popped : bowls of each type of popcorn. They
ensured they popped the popcorn for the same amount of time, used the same wattage
microwave, and did not have any other ingredients added to the kernels (butter, etc).
They counted and recorded the number of unpopped kernels in each of the 10 bowls.
As they analyzed the data collected, they were able to conclude that their initial
hypothesis was supported.
They formed the conclusion that the more expensive brand of popcorn popped more
kernels than the cheaper brand of popcorn.
From this experiment, let's answer some questils.
Was this controlled experiment?
no or yes

Does any one know what real love is and would anyone be willing to share it with me?

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no
