(a)
Answer to Problem 73E
Explanation of Solution
Given:
Concept used:
According to straight line formula:
Calculation:
At
According to straight line formula:
Hence, equation of pressure is
(b)
To sketch:the graph of the linear equation.
(b)
Answer to Problem 73E
The graph is straight line and the graph shows with increasing in depth the water pressure also Increases.
Explanation of Solution
Given:
Concept used:
The graph can be calculated through Desmos graphing calculator.
Calculation:
The graph the linear equation
Here y-axis is pressure and x-axis height or depth.
The graph is straight line and the graph shows with increasing in depth the water pressure also increases.
at
At 0 height ofdepth the pressure is 15
(c)
To find:the slope and intercept of y using representation of graph.
(c)
Answer to Problem 73E
Slope is rate of increase of pressure with depth, and y intercept is pressure at surface of ocean.
Explanation of Solution
Given:
Concept used:
According to straight line formula:
m here is slope of the straight line.
Calculation:
Slope is rate of increase of pressure with depth, and y intercept is pressure at surface of ocean.
