During a practice drill, a runner jogs 10.0 m [W] in 2.00 s, then sprints another 20.0 m [E] in 3.00 s. Determine the runner's: (use v=d/t for questions 8c and 8d)

b.transmitters send radio waves, and receivers capture radio waves.

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
