When energy is transferred from one part of a system to another, some of the energy is lost during the transfer and cannot be used as it was intended. which two sentences describe examples of this? A-sunlight strikes a solar panel, generating electricity. B-wind moves a turbine, generating electricity. C-friction between the moving parts of an airplane engine warms the parts as the engine burns fuel. D-an electric motor heats up as it powers a blender. E-stereo speakers emit sound when powered by electrical energy.

What is created when solids,liquids,an gases mix with one another

*drag each tile to the correct location in the sequence* the table shows chronological events in the life of our sun, a medium-sized star. place the missing events into the correct rows of the table.

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
