Can tsunamis be stopped? Tsunamis could be stopped before they hit the coastline, a Welsh mathematician has proposed in a study of deep-ocean sound waves. Dr Usama Kadri, from Cardiff University’s School of Mathematics, has suggested that firing deep-ocean sound waves at an oncoming tsunami could save lives and reduce on-shore damage. What disaster will […]
Why were Russian peasants so poor?
Why were Russian peasants so poor? The reforms in agricultural also disappointed the peasants.

What color is lowest in energy?
What color is lowest in energy? Red What are the forbidden colors? Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in […]

How do I calculate my daily energy consumption? Once you have those three bits of info, here’s how to calculate the cost: Calculate the daily energy consumption: (Wattage) x (hours used per day) Divide the answer by 1,000. Calculate the annual use: (Daily energy consumption) x (number of days the appliance is used per year) […]
What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
Is 1 degree Celsius cold or hot?
Is 1 degree Celsius cold or hot? In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water compared to 180 degrees in the Fahrenheit scale. This means that 1 °C = 1.8 °F (check the section about temperature differences below). What is the coldest Fahrenheit temperature? The […]
