Consider formula a to be v = startfraction 2 pi r over t endfraction and formula b to be v2 = gstartfraction 2 pi r over t endfraction. write the letter of the appropriate formula to use in each scenario.

determine the tangential speed of the moon given the mass of earth and the distance from earth to the moon.

determine the tangential speed of a satellite that takes 90 minutes to complete an orbit 150 km above earth’s surface.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

bacterium is not correct

then go eat. lol.brainliest
