An airbus a350 is initially moving down the runway at 6.0 m/s preparing for takeoff. the pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.8 m/s^2. the plane then travels a distance of 1500 m down the runway before lifting off. how long does it take from the application of the acceleration until the plane lifts off, becoming airborne?

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
