The posted coordinates place you directly in front of Glasgow Science Centre; home to dozens of interactive Physics exhibits.
Somewhere nearby, a cache is hidden - but you will need to answer some Physics questions in order to find it! All of the questions are based on the Scottish National 5 Physics curriculum (equivalent to the GCSE Physics curriculum in the rest of the UK) so should be answerable by anyone who has studied the subject up to (or beyond) age 16, though you might need to do a little bit of revision and/or additional research first.
Dynamics
A 15kg object is acted on by three forces: 3 N North, 6 N East, 2 N West. The magnitude of the resultant force, measured in newtons, is A.
Space
A star is 1.20719 x 1017m from the Earth. Calculate it's exact distance in light years, then round this figure to the nearest whole number. This number is BC.
Electricity
A 148 Ω resistor and a 110 Ω resistor are connected together in parallel. The combined resistance of these resistors, measured in ohms and rounded to the nearest whole number, is DE.
Properties of Matter
42,000 J of energy is added to 2.5 kg of water (c = 4,200 J kg-1 ºC-1). The initial temperature of the water is 13 ºC. Assuming that no energy is lost to the surroundings, the final temperature of the water (after the 42,000 J of energy has been added) is FG.
Waves
A wave has a wavelength of 3 m and travels a distance of 60 m in 4 s. The frequency of the wave, measured in hertz, is H.
Radiation
100kg of biological tissue absorbs 235 J of energy in the form of alpha radiation. The equivalent dose received by the tissue, measured in sieverts, is IJ.
Final Coordinates
The cache can be found at: N55° AB.CDE, W004° FG.HIJ
Please be careful when retrieving and replacing the cache as it is located in a busy area.
