Sally is a surveyor in the badlands in South Dakota. At point A on the south side of a deep canyon, she sights across to a fire tower on the north side of the canyon at point B. Then she moves a measured 500 feet along the south rim of the canyon to a point C on a line perpendicular to her original sight line AB. Setting up her transit again, she finds that her line of sight, CB, to the tower is 84 degrees. Correct to the nearest whole foot, how far is point C from the tower?

in DNA probe, short single stranded dna labelled with radioactive is mixed with the double stranded dna fragment that contains gene of interest. dna probe is usrd to locate gene of interest in the dna. the question is how do scientist know the base sequence of the radioactively labelled dna before it is mixed with the double-stranded dna fragments that contain the gene?

i hope u can understand the ques. it's a bit hard for me to explain this thing...thanks in advanced.

i have a homework problem i have been workin on for hours now and i cant understnad it .....
A ducks mass = 2.9 kg. As the duck paddles, a force of 0.08 N acts on it in a direction due east. the current of the water exerts a force of 0.27 N in a direction of 41° south of east. When these forces begin to act, the velocity of the duck is 0.12 m/s due east. what is magnitude and the direction (relative to due east) of the displacement ofthe duck after 3.4 s while the forces are acting.

that is my homework problem i would like someone not to do it for me but maybe talk me through how to set up a problem like this so i can learn it myself...
