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

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

model Data Inspection First we will smooth the series by transforming the data on oil demand into their logarithmic form. The log transformation allows the model to be less vulnerable to outliers in the data‚ and thus enables for a more precise forecasting model. Next the data series must be checked for trend and seasonality. Figure 1.1 shows the time series plot for the log transformation of oil imports in Germany from 1985M01 until 1996M12.

What are some examples of imperialism today? How is it different or similar from the past? Explain Today imperialism has ethnic conflicts intensifying and it’s crazy how this world is getting. Not everybody is realizing what is happening though but the little problems from fifty years have increased almost rapidly. No matter what state a person visit they will have imperialism happening because the creation of unequal economic‚ cultural‚ and territorial relationships between states. Imperialism

Action Potentials An action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. An action potential occurs when a neuron sends information down an axon‚ away from the cell body. A threshold is the minimum amount of stimulation needed to start a neural impulse (you know‚ the electrical impulses that travel throughout your body carrying important information). Action potentials generated by neural impulses are

And how can students prepare for these tough test? Schools are allowing too much standardize test‚ and students need to be prepared for that. Testing can be a struggle‚ especially when students have to take a minimum of 21 assessments per year‚ But some people have taken action‚ governors across the states have worked to eliminate seven of those test. The educations Writers Association have added onto this saying‚” On average‚ students are tested once a month‚ or even two times a month.” These test

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

Your rental property needs new occupants‚ so where find potential tenants. Before handing over the keys to the home‚ you need to make sure quality tenants are signing the lease. Besides the tenants‚ there are other things you need to keep in mind. Here are three things a property management company can help you avoid. The Unruly Tenant and the Eviction Process A terrible tenant is a landlord’s worst nightmare. Handling the daily tasks of being a landlord is stressful‚ but unruly tenants can make
