Which of these is not true about the standard model of elementary particles currently accepted by most physicists? a.) it seems to explain every relevant experiment that can be done. b.) it connects the color theory to the strong force. c.) it combines two of the four basic forces into an "electroweak" interaction. d.) it combines the electroweak interaction with the color interaction. e.) it calls for mathematical calculations that are currently impossible.

How much work does the charge escalator do to move 2.30 μc of charge from the negative terminal to the positive terminal of a 3.00 v battery?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
