Amass of sunken lead is resting against the bottom in a glass of water. you take this lead, put it in a small boat of negligible mass, and float the boat in the water. which of the following statements are true? (there may be more than one correct choice.)
a. the sunken lead displaces a volume of water equal to the lead's own volume.
b. the floating lead displaces a volume of water equal to the lead's own volume.
c. the sunken lead displaces a volume of water whose weight equals the lead's weight.
d. the floating lead displaces a volume of water whose weight equals the lead's weight.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Distinguish between a transverse wave and a longitudinal wave.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
