Do you age if you travel speed light? Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth. When the spaceship returned to Earth, the people onboard would come back 31 years in their future–but they would be […]

What are the four evidence of continental drift theory? Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and […]

Which frozen liquid melts the slowest? Water melted the slowest with an average of 145 minutes. Next was sweet tea, which melted in 119 minutes. Do frozen liquids melt at the same rate? A 1 pound block of ice and 1 pound of ice cubes melt at very different rates. The only difference between the […]

How much power does a train engine generate? How many horsepower is a diesel locomotive? A locomotive’s diesel engine is connected to an electric generator that is either DC or AC. In either case, the power produced is around 3,200 horsepower. The generator uses this power to convert it into a massive amount of current, […]

Does density affect specific weight? Mass is a property and the SI unit for density is [kg/m3]. The Imperial (U.S.) units for density are slugs/ft3 but pound-mass per cubic foot – lbm/ft3 – is often used….Specific Gravity for some common Materials. Substance Specific Gravity – SG – Hydrogen 0.00009 Lead 11.35 Mercury 13.59 Nickel 8.73 […]

Does volume change when liquid is heated? A decrease in temperature caused the water molecules to lose energy and slow down, which results in water molecules that are closer together and a decrease in water volume. When water is heated, it expands, or increases in volume. As water cools, it contracts and decreases in volume. […]
