Answer:
screw and pulley
Explanation:
because they didn't have any of the other tools in that time
Answer:
178 cm3
Explanation:
We know that density is expresses as mass per unit volume hence
Density= mass/volume
Making volume the subject then
Volume=mass/density
Substituting mass with 0.00296 g and density with 0.00001663 g/cm3 then
Volume=0.00296/0.00001663=177.99158147925 cm3
Rounding off, the volume is approximately 178 cm3
Centripetal acceleration is the acceleration of an object that is moving in a circular motion. It is calculated by dividing the square of the velocity to the radius of the circular path. It is calculated as follows:
a = v^2 / r = 4.0^2 / 0.4 = 40 m/s^2
Answer:
without answers to choose from, I'd say make sure you're using the same shape and sized containers, and they're placed in the same locations at the same time. also you'd probably get a more accurate result by leaving them longer than an hour, more like a day or 2, and do it on multiple different days, when the temperature is different each day and then take an average of those days...
Would would have moved a total distance of 2k, because walking is a slower speed does not change distance
