The density of water at 20°C is 0.9982 × 103 kg/m3. (a) What is the density when thetemperature is 22°C? (b) What is the percent change in density? (c) If 23 of water at 20°C iskept in a container with a cross sectional area of 0.5 2, how much will the water level increasewhen the temperature increases from 20°C to 22°C? (Assume that water expands uniformlyover this temperature change – one of the main reasons of sea level rise with globalwarming is due to the fact that warmer oceans occupies more space

it is the second option.

0.55x745.7j and a calculator

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

  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.
