What happened to Galileo satellite? Accomplishments. Galileo changed the way we look at our solar system. When the spacecraft plunged into Jupiter’s crushing atmosphere on Sept. 21, 2003, it was being deliberately destroyed to protect one of its own discoveries—a possible ocean beneath the icy crust of the moon Europa. How much did the Galileo […]

In which state of matter process of diffusion is fastest? gases Which state of matter is faster? Phases of matter A B molecules move fastest in this phase plasma molecules move faster than liquids in this state gas molecules move the slowest in this state solid molecules move around each other in this state liquid […]

Are car bumpers plastic? Most OEM bumpers are made out of plastic and feature an aluminum or steel reinforcement bar hidden in the middle. Some bumpers may also contain polypropylene in order to help absorb energy during an impact. Can I drive with damaged bumper? Is it illegal to drive with a damaged bumper? Depending […]

What is beta decay process? Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +. What is […]

How long does it take for the ball to hit the ground? three seconds Does it take a ball longer to go up or down? While coming down, the force of air drag is upward and the force of gravity is downward, so the ball’s downward acceleration has average magnitude less than g, say adown […]

What are two uses for sonar? Sonar uses sound waves to ‘see’ in the water. NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself. There are two types of sonar—active and passive. What is […]

Is humidity hot or cold? Humidity is the presence of water molecules in the air. High humidity levels are more likely in warm air, because it can hold more water at higher temperatures. If the air in your home is warm, it will also have the capacity to hold a lot of moisture. What is […]

How do you calculate watts? AC three phase amps to watts calculation formula P(W) = √3 × PF × I(A) × VL-L(V) So watts are equal to square root of 3 times power factor PF times amps times volts: watt = √3 × PF × amp × volt. or. W = √3 × PF × […]

What are the two most common carbonate minerals? The two most common carbonate minerals are calcite, CaCO3 (Calcium carbonate), and dolomite, CaMg (CO3)2 (calcium/magnesium carbonate). Which of the following is the best identification of minerals? The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to […]

What happens if an atom is not electrically neutral? Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons. Materials with an excess of electrons are negatively charged. Those with a deficiency of electrons are positively charged. What if there is no electron? You would become plasma as […]
