Consider the window (of area 0.71 m2) of an airplane. If the pressure inside the plane is atmospheric pressure, while the pressure outside is 17 % of Patm, find the magnitude of the force on the window. Ignore the velocity of the airplane (i.e., ignore Bernoulli’s effect).

What is the net force on an airplane window of area 1000 cm2 if the pressure inside the cabin is 0.97 atm and the pressure outside is 0.85 atm? (Outward is defined as positive.)
The pressure in the atmosphere is not a constant but fluctuates as the weather changes. If the pressure outside a window drops by 10.1%, while the pressure inside does not change, what is the magnitude of the force on the window? Assume that the area of the window is 1.3 m2.
Consider the rate of heat conduction through a double-paned window that has a 1.45-m2 area and is made of two panes of 0.715-cm-thick glass separated by a 1.25-cm air gap. You can ignore the increased heat transfer in the air gap due to convection. Calculate the rate of heat conduction through this window, in watts, given that the inside surface temperature is 15.0°C, while the outside temperature is -10.0°C. Make the assumption that the temperature differences across the two glass...
An airtight box has a removable lid of area 1.43E-2 m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 8.41E+4 Pa. The inside of the box is completely evacuated. What is the magnitude of the force required to pull the lid off the box
physics help please PHY121 Sample Final problems: thermodynamics, heat, and fluids 10pts 1. A large chemical tank containing acid springs a leak in a seam at the bottom. The air pressure outside the tank is atmospheric(Patm 1,013 x10s N/m2) and the absolute pressure inside the tank at the top is 1.4 x 10s Pa with the hole being 2.7 m below the level of the acid in the tank. What velocity will the acid exit the tank through the hole?...
can you calculate and explain why? thanks (a) A triangular loop with an area of 4 m2, positioned in the x-y plane, is situated in air in a time-varying magnetic field, as shown in Figure 2. The loop includes a resistor of 10 Ω. The magnetic flux density B is given as t+1 6) Determine the induced emf (electromotive force) in the triangular loop.

3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...

Problem2 (a) Suppose outside temperature is 55 °F while the temperature inside a building is 72 F. The building is heated but not air conditioned, so the partial pressure of water vapor is the same both inside and outside the building. Finally, suppose the dew point outside is 40°F What is the dew point inside? What are the relative humidities inside and outside the building? (We are most comfortable if relative humidity is between 30% and 50%-This question shows why...
Magnetism 1. (4) An unknown particle travelling at a velocity of 2.20x106 m/s to the right as seen by an observer, enters a region that has an electric field of magnitude 750 V/m pointed away from the observer. Ignore gravity for this question. (a) What is the direction and magnitude of the perpendicular magnetic field which would best cancel out the effect of the electric field so that the particle passes through undeflected?
