How do you survive freezing temperature without heat? Here are a few tips to stay warm and happy this winter with no heat: Reduce as much heat loss as possible. Put blankets over all the windows and outside doors, and bean bag draft busters at the base of every door. Adding Insulation Supercharges Your Walls. […]
How do you protect a Mosfet from a short circuit?
How do you protect a Mosfet from a short circuit? The voltage across the internal resistance can be sensed using simple comparator or even a transistor, which switches on at a voltage of around 0.5V. You can thus avoid the use of a sense resistor (shunt), which usually produces an undesirable extra voltage drop. The […]
What are the rules for a series circuit?
What are the rules for a series circuit? In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a […]
Which gun has the most recoil?
Which gun has the most recoil? 950 JDJ. This gun is no joke. It uses 240 grains of powder to push a 2,400-grain bullet 2,100 fps. It bites on both ends though, generating 277 foot-pounds of recoil, or approximately 10 times as much as a 30-06. What rifle kicks the hardest? Petzal: The Hardest Kicking […]

When discussing what makes a material a good conductor you say, “They must resist neutron flow.” readily accept electron flow.” readily accept neutron flow.” resist electron flow.” If you are looking for a material that is a good conductor, you will look […]
When should I watch the Perseid meteor shower?
When should I watch the Perseid meteor shower? Perseid meteors have been streaking across our skies since around July 17. We’ll see Perseids for 10 days or so after the peak mornings on August 11, 12 and 13, though at considerably reduced numbers. Yet, each day as the moon wanes in the morning sky, less […]

Which activity produces the smallest amount of greenhouse gases? Riding a bicycle produces the smallest amount of greenhouse gases. Is the concentration of atmospheric carbon dioxide is currently decreasing due to […]
What force is used to lift a weight?
What are three primary methods of monitoring volcanic activity?
What are three primary methods of monitoring volcanic activity? Volcanologists use many different kinds of tools including instruments that detect and record earthquakes (seismometers and seimographs), instruments that measure ground deformation (EDM, Leveling, GPS, tilt), instruments that detect and measure volcanic gases (COSPEC), instruments that determine how much lava is … How can we detect […]
Which country has no volcanoes?
Which country has no volcanoes? Even though Australia is home to nearly 150 volcanoes, none of them has erupted for about 4,000 to 5,000 years! The lack of volcanic activity is due to the island’s location in relation to a tectonic plate, the two layers of the Earth’s crust (or lithosphere). In which country volcano […]
