A 3.9 kg object has a volume of 0.8 m^3. What is the weight density of the object? (answer with units) You are told that the volume of a sphere is given by V=\sqrt{d^3/4}, where V is the volume and d is the diameter of the sphere. ...
This equation is for oxygenic (oxygen evolving) photosynthesis since it uses water as an electron donor and produces oxygen gas. WHERE DOES PHOTOSYNTHESIS OCCUR? Photosynthesis occurs in many unrelated organisms from extremely small cyanobacteria that measure only a few microns to giant sequoyah trees,...
In mathematics, finding an event's probability means you are finding the likelihood that a particular event will or will not happen. Mathematical 'events' can be anything from a particular number coming up on a pair of rolled dice to a certain color ball being pulled out of a bag. Usually...
Here is the basic idea. Let us call the tubes in “thin tubes”. We can try to group these thin tubes into “fat tubes” of dimension for some intermediate scale ; it is not terribly important for this sketch precisely what intermediate value is chosen here, but one could for instance ...
The wave equation is usually expressed in the form where is a function of both time and space , with being the Laplacian operator. One can generalise this equation in a number of ways, for instance by replacing the spatial domain with some other manifold and replacing the Laplacian with the...
Recall that the equation for the capacitance between two parallel plates is a strong function of electrode separation/dielectric thickness; if the distance between the plates is changed (such as by application of a mechanical force) the capacitance changes also. If the capacitance changes but the ...
Anyone who has watched the movement of waves on water can understand the wave equation, one of the most basic relationships in physics. The two parameters you need to calculate a wave's velocity are its frequency -- the number of wave crests that pass a
The basic equation in words is ÀÁ Force ¼ property ´ ðmeasure of responseÞ Physical scientists refer to forces acting on materials in terms of stresses, or force per unit area. The response is either quantified in terms of the amount of deformation, i.e. strain, or the ...
Students are given the materials to conduct various procedures. They construct a procedure for each of the eight changes to be observed, have their procedures approved by the instructor, and then carry out the procedures. The data collected is used to develop a set of criteria for determining ...
Before starting any business it’s important to see both sides of the equation. There are many aspects to tree farming that make it seem almost too good to be true, but there are difficulties and drawbacks too. Here are the pros and cons of growing trees for money. ...
