Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:

1. Why do some scientists believe that there might have been life on Mars? Some scientists believe there was life on Mars due to a number of factors. For one we know there was at one point a substantial amount of liquid water when the planet was much younger. We also know Mars’s electromagnetic field has dampened‚ making it more susceptible to interstellar heat and radiation‚ thus eliminating the life that could have existed. There are also other several factors including volcanic activity and evidence

I‚ as a consumer‚ have gone through multiple reasons why I should buy a Vespa. And here one will find a breakdown of my 5 step buying decision process: 1)PROBLEM RECOGNITION: I recently discovered how problematic having a car was in Manhattan. It ate up fuel‚ was adding more carbon dioxide to the already polluted city‚ was time consuming due to parking and traffic

second lab activity dealt with two-point acuity. Different parts of our body performs a specific function that which they were built to execute. However‚ the sensitivity each surface of our body reveals to be different. Some areas of the body will have a variety of sensory receptors‚ which requires more sensory input. Therefore‚ body parts have their own sensation depth that one can measure through two-point acuity. Results Participant #1: Initially‚ the researcher placed the compass points with
