CBSE Class 12 Physics exam: 5 key formulas to high marks
Here are some important laws and theorems in physics that are often covered in the CBSE Class 12 Physics syllabus: The current flowing through a conductor is directly proportional to the potential difference across its ends, provided the physical conditions such as temperature remain constant.1. Ohm's LawThe rate of change of momentum of an object

The physics of fire ant rafts could help engineers design swarming robots
Fire ants form a protrusion from an ant raft. Credit: Vernerey Researcher Group at CU Boulder Noah rode out his flood in an ark. Winnie-the-Pooh had an upside-down umbrella. Fire ants (Solenopsis invicta), meanwhile, form floating rafts made up of thousands or even hundreds of thousands of individual insects. A new study by engineers at…
Weird Physics: The Closer You Get to the Sun, the Cooler It Gets
One of the weird things about space is that things don't always conform to what would seem like common sense. Take the sun, for example. You'd think that the sun's surface would be hotter than its outer atmosphere, since, the surface is closer to the nuclear furnace at the sun's core. After all, when you're…
