Which best describes Rutherford's theory of the atom?

The atom is mostly empty space, with a nucleus in the middle

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 three subatomic particles

What is the dual nature of light?

Light behaves as a particle and a wave

Light can be both dim and bright

Light has both speed and location

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

What is the purpose of this machine that contains a spinning magnet?

It's used to generate electricity as natural resources cause it to spin.

It's a weapon of mass destruction

It's used to spy on our enemies

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?

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)

The middle east produces more fossil fuels than we do

Fossil fuels are difficult to drill from the ground

The statement "Energy cannot be created or destroyed, only changed in form" is also called...

The Law of Conservation of Energy

What might be considered an exception to the Law of Conservation of energy?

E=mc 2 (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.

How does this nautilus shell show evidence of being designed by a Creator?

The length of each spiral follows a mathematical pattern

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

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'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.

Newton said that every action has an equal and opposite reaction.

Gravity cannot be created or destroyed, only changed in form.

Which theory was strengthened by observations taken during a total solar eclipse?

Einstein's law of gravitation as the warping of spacetime

Einstein's law of mass-energy equivalence

Einstein's photoelectric effect

Newton's Law of Universal Gravitation

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.

Why is the SI system universally used for scientific work?

It is easier to share results with other scientists if everyone uses common units.

It is easy to convert between units in the metric system using powers of 10.

So that fewer mistakes will be made.

Scientists prefer to measure in units like Fahrenheit and gallons
