A75.5-kg person puts on a life jacket, jumps into the water, and floats. the jacket has a volume of 3.38 x 10-2 m3 and is completely submerged under the water. the volume of the person's body that is underwater is 6.42 x 10-2 m3. what is the density of the life jacket?

Density of jacket will be

Explanation:

We know that weight of water displaced= buoyant force=weight of man

Now volume of water displaced

Density of water

So weight of water displaced

So weight of jacket = 98-75 = 23 kg

We have given volume of the jacket =

So density of jacket

i think it'll be 7,000

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
