A 20-m3 tank contains nitrogen at 23 C and 600 kPa. Some nitrogen is allowed to escape until the pressure drops to 400 kPa and the temperature to 20 C. Determine the amount of nitrogen gas that has escaped in kg. How much in this in Kmoles?

## Why single interrupt is interpreted as multiple interruptsAssume that the I bit for external hardware interrupt IRQ is enabled and is low-level triggered. Explain how this interrupt works when it is activated. How can we make sure that a single interrupt is not interpreted as multiple interrupts |

## Which false negatives are significantly more seriousFalse positive and false negative rates can be adjusted, and they are often complementary: Lowering one raises the other. List two situations in which false negatives are significantly more serious than false positives. |

## What is the minimum bandwidth necessary on transmission lineA transmitter is using a 2B1Q and operating at 3 Mbps. What is the minimum bandwidth necessary on the transmission line for successful communication |

## What is the direction of the friction force on the upper boxYou are lowering two boxes, one on top of the other, down the ramp shown in the figure by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 16cm/s. |

## Determine the depletion scr layer width wAn ideal abrupt silicon pn junction has a \(N_{A} = 2 x 10^{17} cm^{-3} , N_{D} = 2 x 10^{15} cm^{-3} , \) 1) With derivation steps, calculate internal potential barrier V0 at 300K and 400K, respectively |

## Find the line-to-line voltage of the line at the sending endA balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load. |

## Determine the charge and current flowing in the circuitThe capacitor in an RC circuit (R=10.0k Ohms and C=25.0uF) is initially uncharged. Determine the charge and current flowing in the circuit at 0.40 time constants (t=0.40 tau) after the circuit is connected to a 9.00 V battery. |

## Find speed of an electron beam coming from an electron gunThe axis of the cylinder is along the z axis, and the electrons are moving with a velocity vector v in the positive z direction. The velocity of the electrons is 0.1c where c is the speed of light (2.99792458 ´ 108 [m/s]). The magnitude of the cur.. |
