You are a scientist working on increasi'ng the efficiency of appliances to waste less electricity. you are running experiments measuring the input, output, and waste energy from 3 miniature particle accelerators. given the data below, determine which model has the lowest percentage of energy lost as waste. accelerator 1: 2078.3 joules in, 663.1 joules wasted, 1415.2 joules out accelerator 2: 7690.0 joules in, 2337.5 joules wasted, 5353.5 joules out accelerator 3: 4061.9 joules in, 2259.6 joules wasted, 1802.3 joules out a. accelerator 3 b. accelerator 2 c. accelerator 1 d. they are all equally efficient

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

nah.   i'm just sleepy.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
