The wind in this picture is blowing from right to left... What is probably true about the air pressure? * There is an area of HIGHER PRESSURE to the RIGHT.
There is an area of LOWER PRESSURE to the RIGHT.
The pressure on the RIGHT is about EQUAL to the pressure on the LEFT.
It is IMPOSSIBLE TO TELL what is happening with the air pressure in this picture.

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

What is work? how much work is done to move an object 0 meters?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
