Why does my balloon car not move? Some of the things that slow balloon cars down, that you have to overcome, are their own weight, air resistance, friction, and inefficient use of the air escaping the balloon. Which type of balloon would deflate the fastest? Helium balloons How much does it cost to fill 100 […]
Does phenolphthalein turn pink in acid or base?
Does phenolphthalein turn pink in acid or base? Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to the class of dyes known as phthalein dyes. What is the pH range for the color change of phenolphthalein? Indicator […]
What is positive decision making?
What is positive decision making? Positive decision makes attempts to seek out all alternative outcomes and sets about achieving the best of those outcomes. Planning. Negative decision making, being based on the absence of negative consequences, has little opportunity for planning. What defines a good decision? A good decision is one that is made deliberately […]
What is the most probable reason why a life jacket helps you float in water?
What is the most probable reason why a life jacket helps you float in water? The trapped air weighs much less than the weight of the water it displaces, so the water pushes up harder than the life jacket pushes down, allowing the life jacket to remain buoyant and float. This buoyancy is strong enough […]

Which is better PNP or NPN transistor?
Which is better PNP or NPN transistor? A NPN transistor has electrons as majority charge carriers whereas the PNP transistor has holes as majority charge carrier. The mobility of electrons is better than mobility of holes. mobility of electrons is more than hole,so as a result npn transistor are faster than pnp that’s why they […]
