Find the particle's horizontal position x(t) and velocity v(x) at any point in a fluid whose drag force is expressed as Fdrag = kmv %3D

Bowling balls are roughly the same size but come in a variety of weights. Given that the official radius a bowling ball should have is roughly 0.111 m, calculate the weight of the heaviest bowling ball that will float in a fluid of density 1.100 × 10° kg/m³. weight: N

Consider the rectangle with length a = 1.8 m and width b= 1.5 m, located d=0.7 m below the water surface. Determine the resultant force P due to the water acting on the rectangle. P= Round your answer to 2 decimal places. kN ho= Round your answer to 2 decimal places. m

A certain fluid has a density of 1080 kg/m3 and is observed to rise to a height of 2.1 cm in a 1.0-mm-diameter tube. The contact angle between the wall and the fluid is zero. Calculate the surface tension of the fluid.

An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air.

Q.5) On long strands form by cobwebs, water vapor condense at night to form long cylinders of water. The cylinders may collapse to form spherical droplets separated by a certain distance. Find the maximum distance (in mm) between droplets formed. Surface tension= α, radius of cylinder r = 2 mm. I

The wing span of an Airbus A300 is 44.8 m.a) What area is swept out per second when the plane is in level flight at 250 m s-1?
