It is the energy emitted per unit time; the power. \n\nTherefore, its dimensional formula is Mass x Length^2 / Time^3.\n\nOr ML^2T^(-3).

Well, here is mine that i got graded on. (8th grade) i hope it helped (100%)\nMatter- Anything that has volume or Mass (EVERYTHING HAS MATTER) (Also, matter IS NOT Weight!!!)

It has width, depth and length. However it does not have time. because it has no mass. Empty space is certainly something but it has and probably will be a paradox for a long long time. At one time the "fabric" of space was reffered to as the "ether" as in ethereal, but even this ascribes to much "material" to empty space.

The work done is force times length. The force acting in this case is just gravitational force which is also the weight. So you will get \n\nA=M*L\n\nM-weight, L-length, A-work\n\nDon't forget to convert Length to meters.

Someone posted the exact same set of questions a few days back, either here or on the physics page - you ought to be able to find the methods in the responses. Have a look.\n\n\nBest of Luck - Mike

a)7:30 + 3:42 =  11:12    Just add minutes it gives 72 but sixty minutes is an hour so 72 = 1 hour and 12 minutes keep the 12 in minutes section and carry 1 hour to hour section.7+3 =10\nAdd carry 1 you get 11.\n\nb) 18:30-3:42 =   14:48  ...Proceed similarly this time you need to borrow 1 from hours section that becomes sixty minutes subtract 42 from 60+30\n\nc)3+42/60 = 3.7 hrs\n\nd)370/3.7= 100 km/hr

1- gravity , elastic forces (as in bows and catapults), Archimedes' push   - In Galileo time was discovered air pressure (Torricelli experiment) \n\n2- Mass \n\n3- Forces add up for the same mass, then acceleration also adds up :   F1 is force from friend 1, A1 is acceleration/thrust  given by him  \nF1= m.A1 \nF2= m.A2\n\nF1 + F2 = m. (A1 + A2)

The best way to work this out would be to plot a speed time graph for the information.\n\nOr you could express it as a simultaneous equation.
