To solve the problem it is necessary to apply the concepts related to heat flow,
The heat flux can be defined as
Where,
k = Thermal conductivity
A = Area of cross-sectional area
d = Length of the rod
Temperature difference between the ends of the rod
Thermal conductivity of copper rod
Area of cross section of rod
Temperature difference
length of rod
Replacing then,
From the definition of heat flow we know that this is also equivalent
Where,
Mass per second
Latent heat of fusion of ice
Re-arrange to find 
Therefore the mass of ice per second that melts is 0.032g
Waves: can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.
In Physics, there are two main (2) types of wave and these are;
- <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
- <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.
Basically, some of the phenomenon associated with waves include the following:
I. Doppler shift (Doppler effect).
II. Reflection.
III. Refraction.
IV. Diffraction.
V. Constructive interference.
VI. Destructive interference.
In conclusion, all waveform can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.

Answer : The mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
Explanation :
As there are two systems for measuring the units which are English and Metric system.
The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.
The English system measured the things in feet, inches, pounds, mile, etc.
As we are given the mass of cereal in 978 grams that means 987 grams is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 28.350 grams = 1 oz
So, 987 grams = 
= 34.815 oz
As we are given the mass of cereal in 34.5 oz that means 34.5 oz is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 1 oz = 28.350 grams
So, 34.5 oz = 
= 978.075 grams
Therefore, the mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
