What is the approximate force the Earth would exert on a 10 kilogram object?
ASAP ANSWERS PLS :D

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. 

The density of the block of iron is lees than the density of mercury but the density of the block of iron is greater than the density of water

Answervery cold;

Your answer would be false
