~2.7 m/s. The circumference of the carousel, therefore the distance, is 22 meters, or 2 pi radius. Dividing that by the time will give you the velocity. Therefore, 22m / 8.2 seconds equals 2.7 m/s.
The correct answer is D. All of these. Trust me I did this question.
Equals variation in position over variation in time, here’s the formula hope it helps :)
Ns
When the force on an object is multiplied by the time it is acting, the Impulse of a force is generated. This is a vector unit and is equal to the change in momentum with its unit as kilogram meter per second (kgms) or Newton Second (Ns)
Density can be kg/m^3 or g/cm3
In g/cm3 density =mass /volume =111g/23cm3
=4.826g/cm3.
In kg/m3,density=mass/volume. converting mass in grams to kg, 1000g=1kg,111g=0.111kg.
cm3 to m3, 1cm3=10^-6m3, 23cm3=0.000023m3
density=0.111kg/0.000023m3 or 2.3*10^-5=4,826.1kg/m3.
the other is a long process.
