JUST NEED TO CONFIRM AN ANSWER The diagram on the right shows a block being pulled across a level surface by a tension force T in a rope that is at angle θ above the ground. The normal force on the block Fn and weight of the block W are also shown. Which of the following would happen if the magnitude of the tension force T stays the same, but the angle θ increases?
A. The weight of W of the object increases
B. The weight of W of the object decreases
C. The normal force Fn on the object increases
D. The normal force Fn on the object decreases.

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?
