1 A large stone block is to be part of a harbour wall. The block is supported beneath the surface of
the sea by a cable from a crane. Fig. 2.1 shows the block with its top face a distance h beneath the

The force acting downwards on the top face of the block, due to the atmosphere and the depth h
of water, is 3.5 X 10^N.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

The answer would be a

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
