The blue light from the screen suppresses melatonin The blue light that your smart phone emits is not only bad for your vision, but it’s bad for your brain too. Dr. Walia says that research has found a correlation between suppressed levels of melatonin […]
Can a plane fly through a storm?
Can a plane fly through a storm? All planes are designed to fly through storms and have to comply with safety regulations. A rainstorm is unlikely to cause damage to the aircraft. The only danger of flying through a rainstorm is the risk of freezing rain, but in this case, your plane will most likely […]

What is the highest compression ratio for 91 octane?
What is the highest compression ratio for 91 octane? about 10 to 1 Does higher compression increase horsepower? The generally accepted gauge for adding compression is that one full point of compression can add between 3 to 4 percent power. So, if an engine is making 50 horsepower and we add a full point of […]
What is the difference between transpiration pull and capillary action?
What is the difference between transpiration pull and capillary action? Capillary action is the attraction between water molecules and the walls of the xylem vessels, causing water movement upwards through the roots, stem and into the leaves. Transpiration pull is when the loss of water from the leaves called transpiration causes water to be pulled […]

Can you test continuity on a live circuit?
Can you test continuity on a live circuit? You can measure the voltage and the current of a live circuit and use those figures to calculate the resistance (Ohm’s Law), but you can’t actually measure the resistance of a live circuit. For a number of reasons, you need to turn the power off and measure […]
