Which of the following statements is false?
Oct 22nd
Question by winnie g: Which of the following statements is false? Which of the following statements is false? Answer Although the Sun influences the tides, its effect is considerably less than the effect of the Moon. The energy that creates surface ocean currents comes from prevailing winds. Elevated wave-cut platforms in Southern California are evidence that this coastal area is emergent. A baymouth bar is a manmade feature designed to control wave erosion.
Best answer:
Answer by Earth ManA bay mouth bar is a natural creation. Imagine that a beach ends at an embayment, and that a longshore current is carrying sediment into More >
Where does the energy or force come from that lifts water against gravity up a paper towel by capillary action
Oct 21st
Question by Dr. J.: Where does the energy or force come from that lifts water against gravity up a paper towel by capillary action Water has mass and therefore requires a force to lift it up against gravity. It seems possible that when water falls, it creates a spring-loaded surface potential energy, which causes the meniscus. However, once this possible potential energy springs water up onto the paper towel, it is consumed, and further climbing up a paper towel, as high as three or four inches, seems “inexplicable.” Is there a M Super Symmetric String Theory explanation, using gravitons More >

Growing Improvements in Statistics of Renewable Energy
The global level of carbon dioxide released from energy emissions continues to grow. This is despite the small decline in fossil fuel emissions caused by reduced economic activity as a result of the economic crisis experienced in the industrialized world. Canada is the fifth-largest global power producer. It has an unparalleled wealth of both renewable and nonrenewable energy resources. Of course, it is widely known for the dirty tar sands production in Alberta, which constitutes 40 percent of Canadian oil production. Over 66 percent of its oil production is exported More >

BP: Lessons Learned from an Internal Investigation
Almost six months after the largest oil spill in American history, BP has issued a report for the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement. The report is titled ”Deepwater Horizon Containment and Response: Capabilities and Lessons Learned.” The report describes what went down during the Deep Horizon incident and what is being done to ensure an event like that doesn’t happen again. That same week, BP released another report based on findings from the internal investigation at BP that was launched to determine the causes of the explosion and spill.
The thing I like the most about these More >

Diving Into the Deep – Unchartered Mental Oceans
Article by Gregory Frost
Just how deep can you go with abyssal mind stimulus is a query umpteenth have asked themselves as they pondered over the many new products that promise to reprogramme the unconscious mind. The term unconscious denotes that within your brain, there is an awareness, a pre conception of a thinking and living psyche that resides abyssal within the cortex. It is not something that is tangible, something that can be placed under a microscope, but it lives and runs as omnipresence if you like, that has outstanding command More >
Q&A: How do you tell the effeciency of a electrical power plant when they give you temperatures?
Oct 8th
Query by redmessssss: How do you notify the effeciency of a electricity plant when they give you temperatures? A proposed electricity plant will use warm water from the surface of the ocean (at thirty degrees celcius) as an energy source. The condenser will use colder drinking water pumped up from a 2000 foot depth (at 10 degrees celcius). What is the maximum efficiency this plant can accomplish?
This is from my thermodynamics course.
Ideal reply:
Reply by wingstwoThe Carnot equation decides the greatest theoretical efficiency.
eff = 1 – Tc / Th = 1 – (10+273.fifteen)/(thirty+273.fifteen) = 6.597% This is not substantial, More >
Function and Electricity problem?
Oct 7th
Problem by Avad: Work and Energy dilemma? A stone is thrown from the edge of a cliff into the ocean below. It is thrown fairly upward, but largely outward. The stone has a mass of two. kg and is thrown with a speed of 10 m/s from an preliminary peak of 5. m over the ocean.
(a) What is the kinetic vitality of the stone when it is thrown? (b) What is the prospective vitality of the stone relative to the ocean when it is first thrown? (do) What is the kinetic electricity of the stone just as it hits the h2o? More >
