For a box with a total surface area of 1.2 m2, the thermal conductivity of the insulating material is mathematically given as
k=5.29*19^{-6} kcal/(s oC m)
<h3>What is the thermal conductivity of the insulating material?</h3>
Generally, the equation for the is mathematically given as
P=Ka dT/L
Therefore
k=10*4*10^{-2}/1.2*1.5
k=5.29*19^{-6} kcal/(s oC m)
In conclusion, the thermal conductivity
k=5.29*19^{-6} kcal/(s oC m)

If lens is replaced by lens then total magnification is
Answer:
Q = 41800[J]
Explanation:
These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.
where:
Q = Heat absorbed [J]
m = mass = 2 [kg]
DT = temperature change = 5 [°C]
Cp = specific heat of the water = 4180 [J/kg*°C]
Units of energy (Joules) [J]
Tiffany has been waiting for weeks to see one particular meteor shower that peaks around august 12. Tiffany is waiting to see Perseid Meteor Shower.
A very bright supermoon known as a "Sturgeon Moon" may make it difficult for photographers to capture this year's climax of the Perseid Meteor Shower tonight (August 12). The Perseid meteor shower, which peaks overnight on August 12 and 13, is one of the most powerful annual meteor showers and occurs between July 14 and September 1. Unfortunately, that falls on the night of this month's full moon, which became fully illuminated yesterday night (Aug. 11). The meteor shower is named after the constellation, the northern constellation Perseus.

Answer:
Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.
