One at x 0 m and the other at x 2 m om has a maximum charge of -23 c, and the plate at x 2m has a maximum 3. [26.8] there exist two conductors charged to capacity: the plate at x = charge of +23 c. because of various factors in the dielectric, electric field between the two ca can be modeled by e=(- 3x2 -- )i. [assume all variables are in appropriate si units.] x+1 a) what is the potential difference from the -plate to the +plate? b) what is the capacitance of the system?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

The speed of light can be used to measure the

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
