Transformations in Matter: Understanding Physical and Chemical Changes
Matter is everything around us and it can undergo significant changes in its physical and chemical properties. A physical change may be a transformation of matter without changing its chemical Read more
What can you use to melt rubber?
Use any liquid with a higher density than rubber and with a high boiling point. For example, you can use heavy oils. Pour the shredded rubber into the liquid. Heat Read more
What happens if an electric car goes into water?
If a car is submerged in water, and some of that water gets into the electrical system, the circuit breakers trip. Even simply shutting down the car interrupts the flow Read more
Can the human eye see 240 fps?
The human eye can see at around 60 FPS and potentially a little more. Some humans believe they can see up to 240 FPS, and some testing has been done Read more
How do you calculate the energy lost due to friction?
How do you calculate the energy lost to friction? The energy lost due to friction is equal to the work done by friction, or Ffricd , where d is the Read more
Can you shock yourself with a 9V battery?
Licking a 9 Volt Battery with SparkFun! What happens when you stick your tongue on a 9-volt battery? When we held the 9V to our tongue, about 1-2mA was flowing Read more
Is it possible to make a self running generator?
When the system is used with an inverter circuit, the output from the generator is around 40 watts. The system can be implemented through a few different configurations. The proposed Read more
What causes MOSFETs to burn?
Generally speaking, a MOSFET passing high current will heat up. Poor heat sinking can destroy the MOSFET from excessive temperature. One way of avoiding too-high current is to parallel multiple Read more
What does it mean if reactive power is negative?
Negative reactive power generated means that reactive power is flowing from the utility grid (source) to the generator. This occurs whenever the generator field is under-excited or if an induction Read more
