What weather do cold fronts bring? A cold front forms when a cold air mass pushes into a warmer air mass. Cold fronts can produce dramatic changes in the weather. As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning. […]
Can a small capacitor kill?
Can a small capacitor kill? Obviously the larger the capacitor, the higher the voltage, the greater the risk of a lethal shock becomes. A really small capacitor charged to a high voltage will not kill you, for example a 100pF capacitor charged to 10kV will only give you a mild static shock. Is a 1000uF […]

Is the aurora borealis dangerous?
Is the aurora borealis dangerous? The Northern Lights occur so high up in the atmosphere that they don’t pose any threat to people watching them from the ground.

What is the net force of a rock falling at constant terminal velocity?
What is the net force of a rock falling at constant terminal velocity? Objects falling through a fluid eventually reach terminal velocity . At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. Why does a parachutist does not fall with constant […]
