Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

Question

At 1500H in July, a boulder reaches a maximum temperature of 50degC. The boulder has
an emissivity of 0.95. What is the radiant heat energy transfer from the wall per square
meter?

After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). The sun is the only source of heat and the ice absorbs a mean of 98 J/m2-s, 12.5 hrs per day. The exposed area for heating is 250 km x 50 km and the density is 920 kg/m3. What is the total mass of the iceberg? Express answer in kg and in scientific notation with two decimal places. To input: if the answer is 4.78x1025, input 4.78e25.
