the air pressure at the base of the mountain is 75.0cm of mercury while at the top is 60cm of mercury. Given that theaverage den

1) The buoyant force acting on an object immersed in a fluid is:
where
is the density of the fluid, 
is the volume of displaced fluid, and 
is the gravitational acceleration.
2) We must calculate the volume of displaced fluid. Since the titanium object is completely immersed in the fluid (air), this volume corresponds to the volume of 1 Kg of titanium, whose density is
. Using the relationship between density, volume and mass, we find
3) Now we can recall the formula written at step 1) and calculate the buoyant force. The air density is
, so we have
4) The weight of 1 Kg of titanium is instead:
So, the buoyant force is negligible compared to the weight.

Answer:
towards left
Explanation:
As we know that there is no external force on the system of two cart so total momentum of the system is conserved
so we will say
now plug in all data into the above equation
here we assumed that left direction of motion is negative while right direction is positive
so we can solve it for speed v now
