What is difference between static and dynamic model? The following table describes the differences between static and dynamic models….Static and dynamic models. Characteristics Static models Dynamic models Data partitioning Data is assumed to be evenly distributed among all partitions. Dynamically determined. Estimates are based on linear regression. What is dynamic load simple? Dynamic load is […]

What makes a high sound? If an object moves back and forth quickly, it will cause a high pitch sound, such as that of a bell. The pitch of a sound is determined by how quickly or slowly an object moves back and forth. So, low pitch means slower vibrations and high pitch means faster […]

How is the conservation of soil and water connected? Agriculture depends on healthy soil and water. Fertile soil and clean water are both renewable resources in natural systems and, when managed properly, can also be renewable resources in the context of agricultural production. Soil and water are required resources for life on Earth. Who made […]

What will the transport be like in 2050? By 2050, because of friction-free technologies and advances in material science, the average passenger vehicle will weigh less than 200 lbs. By 2050, because of automation, far fewer pieces, and greatly reduced complexity the average manufacturing time for a vehicle will be less than one hour. What […]

How much does a good telescope cost? A good telescope can cost anywhere from $200 to $8000 US dollars. What size telescope do you need to see galaxies? If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to […]

What are the four main parts of barrier island beach system? Primary Morphological Components Bays and Lagoons: shallow open to partially restricted water areas located in the backbarrier. Marshes: salt-tolerant vegetated areas within the intertidal area of the backbarrier. Tidal Flats- flat, sandy to muddy areas that are exposed at mid to low tide along […]

Are lakes connected to anything? Generally lakes flow into oceans via rivers, not the other way around. The lake is replenished by rainwater, or by rivers often connected to high elevation sources of water, like a mountain. Why are lakes drained? An operable lake drain accomplishes the following: Makes for a safer dam by providing […]

What size neutral do I need for a 200 amp service? 200 A services are usually #3/0 copper. Sometime you can use a reduced neutral, sometime codes prohibit it. What size wire do I need for a 200 amp underground service? You need a minimum of #6 ground or #4 aluminum for 200 amps. Can […]

Why is it important to climb or hike? When hiking or climbing, it is important to be watchful of areas where erosion has occurred, due to an increased risk of rock slides. What is the best mountain to climb for a beginner? 10 best peaks for beginner mountaineers Mount Whitney, California: 14,505ft. Pikes Peak, Colorado: […]

Is water pressure affected by altitude? Elevation changes can add or subtract water pressure from your water system. Each foot of elevation change is equal to 0.433 PSI of water pressure. Think of a vertical column of water. At the bottom of the column the weight of all the water above is resting on the […]
