Homework Statement The Attempt at a Solution i. First I combined 20ohm and 30ohm to make 50ohms. Since this 50ohms and 100ohms is in parallel I have to use 1/Rtotal= 1/r1 + 1/r2... etc and got 33.333 ohms. I added this to 10ohms which ends up being 43.333 ohms. Then I used V=IR and got...

thank you for your time, patience, and help. i really appreciate it!

ah snap. I am rushing this... sry =D P(total)= 302200 Pa F= 302200 x .00004 F= 12.088 N

ah right forgot about the given density P= 101300 + (1025)(9.8)(20) P= 200900 Pa Using P=f/a, I multiply 200900 by (4.0 x 10^-5) to get: f= 8.036 N

pgh 1000 x 9.8 x 20 = 196000 Pa

hmm i see what you mean. ill look into my notes and see if i can find anything on it. *from a glance at the notes, would it have to do something with absolute pressure?

Homework Statement A large tank, 25m in height and open at the top, is completely filled with saltwater (density of 1025kg/m^3). A small drain plug witha cross- sectional area of 4.0 x 10^-5 m^2 is located 5 m from the bottom of the tank. a. calculate the force exerted by the water on the...

Homework Statement Batman, whose mass is 101kg, is holding on to the free end of a 16 m rope, the other end of which is fixed to a tree limb above. He is able to get the rope in motion as only Batman knows how, eventually getting it to swing enough that he can reach a ledge when the rope...

Conical Pendulum--- did I do this right? Homework Statement A ball is attached to a string with length of L. It swings in a horizontal circle, with a constant speed. The string makes an angle (theta) with the vertical, and T is the magnitude of the tension in the string. 1)Determine the...

Ah, I didn't realize that I didn't post the question itself... "Determine the distance between the landing points of the two blocks"

Homework Statement Two small blocks each of mass m, are connected by a string of constant length 4h and negligible mass. Block A is placed on a smooth tabletop and block B hangs over the edge of the table. The tabletop is a distance 2h above the floor. Block B is a distance h above the...

thank you.

Homework Statement "A student whose weight is 500 Newtons stands on a scale in an elevator and records the scale reading as a function of time. The data is shown in the graph above. At time t=0, the elevator is at displacement x=0 with velocity v=0. Assume that the positive directions for...

Does this jump honor the concept of physics?? http://www.youtube.com/watch?v=2YMQR13ia... -James Bond: Casino Royale Explain what is wrong with the action scene and how the segment should be modified so that it honors the laws of physics. The only thing I can think of is that the...

Action Scenes in movies that depict projectile motion?? What are some actions scenes in movies or cartoons that depict projectile motion? This is for a physics project but I can't think of any good scenes to do. I would do the tunnel-helicopter scene in Die Hard 4 but the ramp isn't frictionless...
