A bird moving in air or a fish moving in water experiences a force opposite to its direction of motion. Do you expect any change in the magnitude of this force? (a) If the fluid is heated and temperature is increased by to T0+10°K. (b) If the fluid is cooled down and its temperature is reduced to T0-10°K. Clearly mention your assumptions (if there is any) and justify your answer for each case.

3 A fluid of density 1200 kg/m° at 1 atm pressure is compressed to 101 atm pressure isothermally. If the isothermal compression is 4.8, 105 atm. -1 the 3. increase in density in kg/m of fluid is

A man pushes on a refrigerator. Determine if the refrigerator moves or if the man's shoes slip. If the refrigerator moves, determine whether it slips or tips. Support your answer analytically! Given:Mfridge = 100 kg, Mman = 80 kg, L1 = 1.5 m, L2 = 1 m, L3 = 0.75 m, µfridge-to-floor = 0.3, µshoes-to-floor = 0.4

The weight of an airplane varies with the cube of the plane’s length. The lift generated by an airplane’swings varies with the square of the plane’s length. Will a different airplane with the same constants be able to fly if it is 75 feet long?

Penny is adjusting the position of a stand up piano of mass mp = 155 kg in her living room. The piano is lp = 1.35 m in length. The piano is currently at an angle of θp = 36 degrees to the wall. Penny wants to rotate the piano across the carpeted floor so that it is flat up against the wall. To move the piano, Penny pushes on it at the point furthest from the wall. This piano does not have wheels, so you can assume that the friction between the piano and the rug acts at the center of mass of the piano. Randomized Variables mp = 155 kglp = 1.35 mθp = 36 degrees a. Write an expression for the minimum magnitude of the force Fs in N Penny needs to exert on the piano to get it moving. Assume the corner of the piano on the wall doesn't slide and the static friction between the rug and the piano is μs.  b. The coefficient of kinetic friction between the carpet and the piano is μk = 0.27. Once the piano starts moving, calculate the torque τp in N⋅m that Penny needs to apply to keep moving the…

Pressure at Depth |- 7 ➜ Ĵ h ↓ h Atomospheric pressure, Palm -0cm -30cm +60cm 90cm The pressure at a depth in a fluid of constant density is equal to the pressure of the atmosphere plus the pressure due to the weight of the fluid, or p = po + phg, Where p is the pressure at a particular depth, Po is the pressure of the atmosphere, p is the density of the fluid, g is the acceleration due to gravity, and h is the depth. Concept more important than solution here! -Nozzles -Water jets What is the pressure at nozzle 1? This reminds me of projectile motion with horizontal launch. Why does the water from the bottom nozzle land farther away? Ay What direction is the net 14.4 force at the nozzles? Vertical, horizontal, or a mix? Ax

I need the answer as soon as possible

Question 3: A nearly-full cart of water (p= 1000 kg/m³) is shown at rest in the figure below. The cart begins to accelerate to the right. If the gage pressure at point A= Zero, determine: 1- The acceleration a, in m/s²: 2- The pressure at point B in kPa 30 cm 2m AT 10 cm #h

A diver 50 m deep in 8°C fresh water exhales a 1.2 cm diameter bubble which rises to the surface of the water and has a diameter of 2.2 cm when it reaches the surface of the water. Assume the air bubble rises slow enough that it is always in thermal equilibrium with the surrounding water. Include units in all your numerical responses 1. Determine the pressure of the air inside the bubbles

Which spring, the truncated cone spring or the helical spring, would have a larger spring constant? Explain.
