In a free body diagram for a box on a rough slope, there will be three arrows. One will point out of the box up the slope (parallel to the slope), one will point directly downwards from the box, and the f...
One way of defining potential is:The GPE per unit massWe define an infinite distance from the centre of our field to have zero potential, this means that energy needs to be provided to an object for it to...
T=20.2 degrees Celsius. Start by finding number of moles using n=mass/Mr so n=1.33/32=0.0416. Find the volume in m^3 using 1cm^3=110^-6 m^3 giving V=110^-3 m^3 then rearrange PV=nRT to get T=PV/n...
Micheal should sit at a distance of 1m from the pivot or half whatever distance Jessica sits. This is found intuitively here but can be found with any two masses by resolving moments.
s=((u+v)/2)t1000=((10+22)/2)t1000=(16)tt= 62.5s
