How can I improve my balloon powered car? How to Make a Balloon Car Go Faster Reduce Weight. Examine your car carefully for any opportunity to shed as much weight as possible. Minimize Drag. Drag, or air resistance, is important even at low speeds because the balloon car is so lightweight. Cut the Friction. Improve […]
Do I need to know Physics 1 Physics 2?
Do I need to know Physics 1 Physics 2? All you need to know for Physics 1 (newtonian mechanics) is basic derivatives for velocity and acceleration as well as some integrals for force, work and some moment of inertia problems. Physics 2 requires Calc 2 because you need to know different types of integrals such […]
What are the similarities and differences between primary and secondary succession?
What are the similarities and differences between primary and secondary succession? Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is […]

Do metallic bonds dissolve in water?
Do metallic bonds dissolve in water? Metallic bonds are not soluble in water because: They are held together by strong metallic bonds and so no solvent to solute attractions could be stronger than these, so these substances are insoluble also they don’t have the necessary intermolecular forces (namely hydrogen bonds) that are present in water. […]
Can a referee change his decision after final whistle?
Can a referee change his decision after final whistle? The referee may only change a decision on realising that it is incorrect or, at his discretion, on the advice of an assistant referee or the fourth official, provided that he has not restarted play or terminated the match. If play has not restarted, the referee […]
How do you calculate the change in liquid temperature?
How do you calculate the change in liquid temperature? This is easy. You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees […]
How do volcanologists predict volcanoes?
How do volcanologists predict volcanoes? Earthquakes. Moving magma shakes the ground, so the number and size of earthquakes increases before an eruption. A volcano that is about to erupt may produce a sequence of earthquakes. Scientists use seismographs that record the length and strength of each earthquake to try to determine if an eruption is […]
