Let’s now multiply two numbers in scientific notation using google. enter .0008 into google exactly as it was written above as: we could now multiply it by .000056 by typing: note that we have separated our two numbers by putting them inside parentheses, and the * symbol (shift+8) is used as the multiplication sign. we could have done a division instead of multiplying by separating the two numbers by a forward slash multiply the number 4.48e-8 by 5.2e-4 using google. what is the correct answer in scientific notation? 6.78e-11 3.33e-12 2.40e-12 2.33e-11

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.

Abumper car with a mass of 250 kg is traveling at a speed of 4 m/s. this bumper car collides and sticks to a second bumper car with a mass of 250 kg, which is initially at rest. what is the final speed of these two bumper cars after the collision, assuming they remain stuck together?
