Science Experiment #3

Whilst I've been in Germany there have been complaints about the distinct lack of Heidi Mace-related science experiments on DeDomenici Blog.

So without further ado:


What's Heavier: Mini DV Tapes, or Cheese?

More specifically, which is heaviest, 2x Sony Premium Mini DV tapes 5 packs, or 2x Costcutter Heritage Red Leicester cheese?


















Front Elevation


Method

Without holding the items, Miss Mace estimated that the cheese would be heavier than the tapes.

I then took the items to the second floor, where I weighed them using an electronic scale and noted the results.

Side Elevation


Results

The Cheese was heavier.

But not by as much as one may think.

The combined weight of the cheese was 428 grams, whereas the mini dv tapes were 356g.

That makes the cheese just 72 grams heavier than the tapes.

There was a 4g discrepancy between the two packets of cheese, and, interestingly, a 2g difference in the tapes.

Discovering the source of this 2g variation is beyond the remit of today's experiment, but will be the topic of a future post.

Conclusion

Costcutter Heritage Red Leicester Cheese has over 2x the density of Sony Premium Mini DV Tapes.

All that remains is for me to once again offer Miss Mace my congratulations on her excellent weight assessment skills.

Competition!

Question: if there is a 4g discrepancy between the two packets of cheese, and a 2g difference in the two packets of tapes, and if the combined weight of the cheese is 428 grams, and the mini dv tapes 356g, what are the individual weights of each cheese and tape packet?

Answers below. There is no need to show your working.

The winner gets a prize.
