Sentences with phrase «much energy escapes»

If the beam entrance hole is too small, not enough energy gets through to the target, but if too large, too much energy escapes.

The obvious explanation for this is that something on Earth is stopping as much energy escaping as is entering.

Not exact matches

If floods last for more than a few days, the rice plants expend so much energy trying unsuccessfully to escape that they are unable to recover.

The team tracked the tail stroke rate and cardiovascular response of the narwhals after their release, and determined how much energy the animals used during their deep escape dives.

By tracking the positions and properties of hundreds of millions of randomly distributed particles as they collide and annihilate each other near a black hole, the new model reveals processes that produce gamma rays with much higher energies, as well as a better likelihood of escape and detection, than ever thought possible.

But a photon can give an electron enough energy to escape that pull, much like a video game character getting a power - up to jump a motorbike across a ravine.

If the energy delivered to Earth by the Sun or by impacts (or both) were 40 % greater, the Earth would experience a runaway greenhouse.3 That is, more water would evaporate from Earth's surface, so too much heat trying to escape into outer space would be blocked by water vapor in the atmosphere.

And energy out mostly by radiation, however, as much as 20 % of escaping energy is simply highly energized atmospheric molecules; which furthers vertical convection all the way out to the inside of Earth's magnetic bottle, and the Van Allen radiation belt.

Trenberth's 40 W / m ^ 2 escape via the atmospheric window, also seems too low to me; implying almost complete absorption of the surface emission by the atmosphere whereas spectral plots would seem to allow capture of a much smaller fraction of the total energy.

The atmosphere acts like the glass in a greenhouse, allowing much of the shortwave solar radiation to travel through unimpeded, but trapping a lot of the longwave heat energy trying to escape back to space.

If the atmosphere contained no IR - absorbing substances, then all the IR emitted by the earth's surface would escape into space and radiative balance would dictate that the earth's average surface temperature (or really the average of emissivity * T ^ 4 where T is the absolute temperature and the emissivity of most terrestrial materials in the wavelength range of interest is very close to 1) is set by the condition that the earth must radiate as much energy as it absorbs from the sun.
