Problem 3: An LR circuit includes a basic switch, two voltmeters and an ammeter. Initially the switch is in position "a" and has been for a considerable period of time. A steady current flows. Data collection begins, and after a brief delay, the switch is moved to position "b". R Vo- Part (a) Which graph best represents the current measured with the ammeter as a function of time?

I drive a Nissan Leaf to work. With the e-pedal on, the motor recovers energy through braking very aggressively. I need about 7 KW-hour to come to school if I use mostly the freeways. That’s about 5 KW-hour if I take mostly local streets. From the energy perspective, can you offer an explanation to explain this difference?

d sin 0m = m² What does each of the variables in this equation stand for? Make a sketch to illustrate the use of this equation. 1

A plane flies in two straight-line segments. On the first segment it flies 250 km at an angle of 30 south of west. Then it flies 125 km at an angle of 20 east of south on the second segment. Find the magnitude and direction of the resulting (overall) displacement of the plane  by graphically drawing the displacement vectors and  by calculating the resultant using components

Suppose you walk 15.5m straight west and then 29m straight north as shown in the figure. What is the angle of displacement measured west of north in degrees?

Question 4 a through c for pratice I just know how to calculate and little confused
