20. A student carries out an experiment to determine the specific heat capacity c of a solid. The relationship used to calculate cis
E
CE
maT
The recorded measurements and their percentage uncertainties are shown.
energy supplied, E = 5000 J + 1%
mass of solid, m=0-20 kg + 2%
change in temperature, AT = 4-5 °C -5%
A good estimate of the percentage uncertainty in the calculated value of cis
A 8%
B 7%
5%
C
D3%
E1%.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
