Forces In Creation
The three basic parts of an atom in terms of their size, from smallest to largest.
What are the electron, proton, and neutron?
The 3 types of soundwaves and this one has the shortest wavelengths.
What are Sonic, Infrasonic and Ultrasonic. Ultrasonic has the shortest wavelengths because it has the highest frequency.
This is what light waves osicllate.
The four regions of the sun (from the outside in).
What are the photosphere, convection zone, radiative zone, and the core?
The half-life of the radioactive decay of 226Ra is 1,600 years. If a sample of 226Ra originally had a mass of 10 grams, how many grams would be left after 3,200 years?
2.5 grams
It is the nuclear force, and this is what causes it.
What is the force that hold the protons and neutrons in the nucleus. It is caused by the exchange of pions between the protons and/or neutrons.
The difference between transverse waves and longitudinal waves.
Transverse waves have a direction of propagation that is perpendicular to its direction of oscillation. Longitudinal waves are parallel.
The order of the colors blue, red, yellow, green in terms of decreasing wavelength.
What is red, yellow, green, blue?
What is nuclear fusion that occurs in the core?
Would an alarm on the outside of the international space station be heard by an astronaut in the middle of a space walk?
No, because there is no air for the sound waves to oscillate.
The number of protons, electrons, and neutrons in a 14C atom.
What is
6 protons
6 electrons
8 neutrons?
You are in the middle of a thunderstorm. You see a flash of lightning and, 1.5 seconds later, you hear thunder. This is how far away you are from the lightning if the temperature at the time is 13 degrees Celsius. (Worth 2 points - 1 for the speed and 1 for the distance.)
What is 508.95 m away and at a speed of 339.3 m/sec?
A light ray is traveling from air into glass. If the angle the light ray makes with a line perpendicular to the glass surface is measured, which way will the refracted ray bend from the line?
The light will bend towards the perpendicular line.
This is what happens to the mass of the starting materials in both nuclear fusion and fission.
What is converted to energy? The mass of the starting materials is larger than the mass of the materials the process makes.
Put in order the following, in terms of increasing wavelengths: Radio waves, X-rays, Visible light.
X-Rays, Visible Light, Radio waves.
The daughter product produced in the beta decay of 131I.
What is 131XE?
This is why jets only travel at speeds of Mach 1 or higher in sparsely populated regions.
What is because the shock wave emitted from this speed (a sonic boom) can damage buildings and people's ears?
A shirt is dyed so that it looks yellow. These colors of light are absorbed by the dye.
What are red, orange, green, blue, indigo, and violet light?
Refer to the H-R diagram in your book. This star has a magnitude -7 and spectral letter F.
What is a supergiant?
A star like our sun has a magnitude of 5, what would it's spectral letter likely be?
G-K
The three types of radioactive particles in increasing order of their ability to travel through matter.
What are Alpha particles, beta particles, and gamma rays?
You hear two musical notes. They both have the same pitch, but the first is louder than the second. If you compared the sound waves of each sound, which aspects of them would be the same or different?
Wavelength, frequency, and speed would be the same while amplitude (which determines loudness) would be different.
A cyan dye is made of a mixture of substances which absorb all light colors except blue and green. If you took a cyan piece of paper and placed it in a dark room and shined blue light on it, what would you see? Yellow light?
In the blue light, the paper would look blue. In the yellow light the paper would look black.
As you move from right to left on the H-R diagram, a star's temperature does this.
What is increase?
What has been the best part of your 8th grade year?
