An electron is moving with a speed of 7.75 ✕ 107 m/s as measured by an observer in a laboratory. the electron is at rest in the primed frame of reference and at its origin. if we assume the origins of the reference frames of the electron and the laboratory are coincident at t = t' = 0 and the electron is moving along the +x axis, what is the position of the electron in the primed frame of reference when the position in the unprimed frame is the following? (assume the electron is at the origin in its reference frame at t = 0.)a. 5.0 mmx'= mmb. 5.0cmx'=. 5.0mx'=. 5.0kmx'=

Which is the most accurate name for the ionic compound cas?

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
