They can act as both a particle and a wave.
They are positively charged.
We cannot know how fast they are going or where they are at the same time.
They exist in orbitals (2 per orbital)
Electrons are really weird
Whose atomic theory proposed that indivisible atoms combine in whole number ratios?
Democritus
Dalton
JJ Thomson
Rutherford
Chadwick
Which of the following best describes the plum pudding model of the atom?
Which best describes Rutherford's theory of the atom?
Plum Pudding Model
Indivisible particles
The atom is mostly empty space, with a nucleus in the middle
Electrons live in orbitals
Which of the following best describes Bohr's model for the atom?
What did Chadwick discover?
The proton
The neutron
The electron
The atom
How is the quantum model different from all the previous atomic models?
It has wave-like electrons existing in orbitals.
In has electrons orbiting the nucleus like planets around the sun.
It has a nucleus.
It has three subatomic particles
Which image best describes the process of nuclear fusion that takes place on the sun?
What is the dual nature of light?
Light can be both dim and bright
Light behaves as a particle and a wave
Light has both speed and location
Light has 2 predominant colors
Which of the following is the correct visible spectrum from longest to shortest wavelength?
red, orange, yellow, green, blue, purple
purple, blue, green, yellow, orange, red
yellow, green, red, blue, orange, purple
purple, red, yellow, green, orange, blue
Which is the correct sequence for the regions of the electromagnetic spectrum, from longest wavelength to shortest?
radio, microwave, infrared, visible, UV, X-ray, gamma ray
gamma ray, X-ray, UV, visible, infrared, microwave, radio
microwave, radio, infrared, UV, gamma ray, X -ray
X-ray, gamma ray, UV, infrared, visible, microwave, radio
Which of the following sources of energy is nonrenewable?
geothermal
solar
fossil fuels
wind
What commonly used mechanism generates electricity from a variety of natural resources?
electromagnetic radiation
solar panel
turbine
heat
What is the purpose of this machine that contains a spinning magnet?
It's a weapon of mass destruction
It's used to spy on our enemies
It's used to generate electricity as natural resources cause it to spin.
It's a rocket designed to explore other planets.
Which of the following is NOT a drawback of nuclear energy?
Climate change (global warming from carbon dioxide emissions).
The waste takes thousands of years to decay
Terrorists may get their hands on nuclear material
A nuclear meltdown could make a city uninhabitable
Why are fossil fuels a nonrenewable resource?
They're expensive
The middle east produces more fossil fuels than we do
Fossil fuels are the decayed remains of animals from thousands/millions of years ago. (it takes too long to form new fuel in our lifetime)
Fossil fuels are difficult to drill from the ground
What kind of energy is present when the roller coaster is still, at the very TOP of the hill?
kinetic energy
gravitational potential energy
thermal energy
nuclear energy
The statement "Energy cannot be created or destroyed, only changed in form" is also called...
The Law of Conservation of Energy
Mass-energy equivalence
Law of Universal Gravitation
Newton's Laws of Motion
What might be considered an exception to the Law of Conservation of energy?
E=mc2 (energy can be "created from mass")
A roller coaster losing potential energy as it goes down a hill
A car losing speed as you push on the brakes
The body gaining energy from the food you eat.
Which of the following best describes this illustration of heat transfer?
Convection
conduction
radiation
friction
This is a heat sink that keeps computers from overheating. What best describes the process of heat transferring from the copper pipes to the metal "combs"?
convection
conduction
radiation
friction
I'm sitting on a camping chair and warming my hands by this fire. By what process does the heat transfer from the campfire to my hands?
convection
conduction
radiation
friction
How does this nautilus shell show evidence of being designed by a Creator?
The length of each spiral follows a mathematical pattern
It looks beautiful
Its patterns are similar to those found in flowers, pinecones, pineapples, and other natural places.
It just randomly got to be here by itself.
Which of the following features make earth just right for life?
We are in the Goldilocks zone (not too far nor too close to the sun).
The magnetosphere protects us from radiation.
Water on earth regulates our temperature
The moon makes the earth tilt in order to have seasons
Which of the four fundamental forces is the weakest?
strong nuclear force
weak nuclear force
electromagnetic force
gravitational force
Which of the following best represents a magnetic field?
The pull of gravity actually varies over the surface of the earth. Blue spots have the strongest gravity, and red spots have the weakest. Based on Newton's Law of Universal Gravitation, why might this be the case?
Newton said that every action has an equal and opposite reaction.
Newton's Law of Gravitation says that gravitational force is greater the closer two objects are to one another. The bottom of the ocean is closer to the center of the earth.
Gravity cannot be created or destroyed, only changed in form.
Mountaintops warp spacetime.
Which theory was strengthened by observations taken during a total solar eclipse?
Einstein's law of mass-energy equivalence
Einstein's law of gravitation as the warping of spacetime
Einstein's photoelectric effect
Newton's Law of Universal Gravitation
Newton's Law of Universal Gravitation predicts that light should not be affected by gravity because it doesn't have mass. What part of the Cycle of Scientific Enterprise does this statement represent?
Theory
Hypothesis
Experiment
Analysis
How did Einstein's theory of gravity grow out of Newton's theory of gravity?
An experiment disproved the hypothesis that light shouldn't be affected by gravity, and the theory was revised to incorporate the new results.
Einstein just copied Newton's ideas
Einstein's theory had nothing to do with Newton's theory.
Einstein's theory completely replaced Newton's theory.
Which of the following are ways we can know truth (as opposed to facts)?
scientific experiments
scripture
direct experience
reading it on the internet
