Be sure to answer all parts. in a future hydrogen-fuel economy, the cheapest source of h2 will certainly be water. it takes 467 kj to produce 1 mol of h atoms from water. what is the frequency, wavelength, and minimum energy of a photon that can free an h atom from water? enter your answers in scientific notation. frequency = 7.05 × 10 -32 s−1 wavelength = 4.26 × 10 -25 m minimum energy = × 10 kj/photon

Explanation:

c = Speed of light =

= Avogadro's number =

= Frequency

= Wavelength

The minimum energy is given by

The minimum energy is

The energy of a photon is given by

The frequency of the photon is

Wavelength is given by

The wavelength is

i would say the answer is food.

hope this !

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
