Question 10: (1 point) Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 98 km long, 34.7 km wide, and
200 m thick
(a) How much heat in joules would be required to melt this iceberg (assumed to be at 0°C) into liquid water at 0°C? The density of ico
is 917 kg/m and the latent heat of fusion is 334 kJ/kg.

Units:
(b) The annual energy comsumption for Australia in the 2017-2018 financial year was 6.172x1018 J. If this energy was delivered to the
iceberg every year, how many years would it take before the ice melted?

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.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
