Why do some liquids flow more freely than others? Liquids vary in their viscosity (resistance to flow). A definition of viscosity; “Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Gases also have viscosity

In finance‚ the discounted cash flow (DCF) analysis is a method of valuing a project‚ company or asset using the concepts of time value of money (Wikipedia‚ 2004). Three inputs are required to use the DCF‚ also called dividend-yield-plus-growth-rate approach‚ include: the current stock price‚ the current dividend‚ and the marginal investor’s expected dividend growth rate. The stock price and the dividend are east to obtain‚ but the expected growth rate is difficult to estimate (Ehrhardt & Brigham

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

To define the circular functions sine‚ cosine and tangent. To explore the symmetry properties of circular functions. To find standard exact values of circular functions. To understand and sketch the graphs of circular functions. 16.1 Measuring angles in degrees and radians The diagram shows a unit circle‚ i.e. a circle of radius 1 unit

velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial

It’s going to be a static implementation of queues and good for limited elements to be handled‚ as you know array size has to be pre-defined and can’t be changed dynamically. Here‚ every time you insert a new element in the queue you’ll check for the queue ’overflow’ condition as we are using a static array to implement the queue. Here‚ I’ll take rear as -1 and front as 0 when the Queue is empty. Algorithm:- Step-1: Increment the ’rear’ by 1 Step-2: Check for the ’queue overflow’ condition

thrown by a man in a straight line. Circular motion Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform‚ with constant angular rate of rotation (and constant speed)‚ or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. Examples of circular motion include: an artificial satellite orbiting the Earth at

Strategy Instruction for making hot tea The first step is to discuss our ‘strategy’ or process. At this time I activate prior knowledge. We have a group discussion about kitchen safety‚ what we have learned thus far and then we move into the purpose of learning and we talk about when and why people drink tea; as well we now have an opportunity to see which we prefer hot tea or iced tea. Then we move right into step 2; which is modeling the process for my students. I model each of the following
