The quantity t1/2=τ ln 2 is called the half-life of an exponential decay, where τ=rc is the time constant in an rc circuit. the current in a discharging rc circuit drops by half whenever t increases by t1/2. for a circuit with r=2.0 kω and c=5.0 μf, if the current is 6.0 ma at t=5.0 ms, at what time (in ms) will the current be 3.0 ma?

Which situation will produce the greatest change of momentum

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

Which of these is the best way to manage a natural resource
