From these data, calculate the density of lead in SI A solid piece of lead has a mass of 21.16 g and a volume of 1.88 units (kilograms per cubic meter) 112553 kg/ One cubic meter (1.00 m2) of aluminum has a mass of 2.70 x 103 kg, and the same volume of iron has a mass of 7.B6 x 103 kg. Find the radius of a solid aluminum sphere that will balance a solid iron sphere of radius 2.02 cm on an equal arm balance. Need Heip?ese Type here to searchExplanation / Answer
We have,
x = At^3 + Bt
In order for the equation to be of the position, the final units should be "that of length or meters"
A = L/T^3
B = L/T
A check for the units
x = L/T^3 x t^3 + B/T x t
both T and t have units of time and gets cancelled, so the eqn will be:
x = L + L (units of lengths, can be added)
b)dx/dt = 3At^2 + B
dx/dt = 3 L/T^2 x t^2 + L/T
dx/dt = L/T
(Its the units of velocity, justified as v = dx/dt)
