Which gas plays the largest role in trapping heat energy from the sun?

Water Vapor

Precise instruments show that over the last 65 years the amount of carbon dioxide in Earth's atmosphere has changed by:

About a third (33 percent increase)

Records of temperature measurements averaged over the globe show that over about the last 100 years the Earth's temperature has

increase by about 1 degree C (or 2 degrees F)

During the past few years, what country released the most carbon dioxide per year into the atmosphere through man made uses?

China

What country has released the most carbon dioxide into the atmosphere since 1970 through man made uses?

United States

The approximately one degree (C) of warming of the Earth's surface that has been observed in the last century is most likely due to:

Increase in the amount of C02 in the Atmosphere

The international organization that studies climate change is

IPCC

IPCC has concluded that human influence on the Earth's climate is:

unequivocal

IPCC AR6 WG1 has made predictions of the future climate under five different assumed greenhouse has scenarios. They predict that the very likely uncertainty bands for temperature overlap between the low and high emission scenarios for the next:

50 years

IPCC AR6 WG1 predicts that sea level rise will continue for how long?

for thousands of years

Quantum theory tells us that everything we thought was a particle also behaves like:
a. Energy
b. a beam of light
c. an atom
d. the nucleus of an atom
e. a wave

a wave

The laser operates on the principal of

a photon chain reaction

Transistors work by controlling the voltage between stacks of

Semiconductors

Complex numbers make it easy mathematically to describe

The amplitude and phase of a wave

Quantum teleportation
a. transfers captain kirk to and from the enterprise
b. violates relativity
c. only transfers quantum information
d. only occurs in science fiction

only transfers quantum information

The most useful application of quantum computers (that we've thought of to date) is likely to be

solving problems in quantum mechanics that are too hard with classical computers.
