What feature of a dmm allows you to connect the test probes in the circuit, remove the probes, and then read the measured value on the display? a. diode tester b. minimum/maximum feature c. delta feature d. touch/hold feature which direction do electrons travel? a. they don't move; they simply exchange charge. b. in either direction, depending on the circuit c. from positive to negative d. from negative to positive a circuit contains a 40 ohm resistor and a 60 ohms resistor connected in parallel. if you test this circuit with a dmm, you should read a total resistance value of a. 40 ohms. b. 24 ohms. c. 2400 ohms. d. 2.5 ohms

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
