Process of science: explaining apparent retrograde motion part a at most times, mars appears to move relative to the stars. the exceptions are during its periods of apparent retrograde motion, when mars appears to move relative to the stars. check two responses below, one for each of the two blanks in the question. blank 1) to the right (westward) (blank 1) to the left (eastward) (blank 1) fast (blank 1) slow (blank 2) to the right (westward) (blank 2) to the left (eastward) (blank 2) fast (blank 2) slow

*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.

Inside of a windmill or a dam is a that is used to transform one type of energy into electrical energy. a. motor b. generator c. transformer d. power pack

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
