A car is initially driving at 30 m/s. It hits a large pothole, after which it is traveling in the same direction but at 25 m/s.
Draw vectors representing the initial velocity final velocity, and (hange in velocity which describe the equation : + Δ¡. 2. The SI nit for weight is the Newton (not the kilogram!). Express the weight of a 2.8 lbs. watermelon in Newtons. 3. On Mars gravitational acceleration is aMars 3.71 m/s2 or aMars 0.37g, where g is the gravitational acceleration of on object on Earth. If a future astronaut drops a rock from a height of 1.9 m how long will it take to hit the ground on Mars? Compare that number to how long the same rock would take to fall on Earth.
By copying their genomes, they retain the tool kit and at the same time generate a garage full of spare parts. Gene duplication can provide the raw material for expression changes to occur, and polyploidy itself can trigger epigenetic changes
