Pygmies use blow-guns and 15 gram (0.015 kg) darts dipped in the poison curare to immobilize and kill monkeys that live in the tree-top canopy of their forest home. Assume a pygmy at ground level blows a dark at 85 degrees (relative to the horizontal) at a monkey that is 35 vertical meters up...

oh haha ^^;; Ill make note of that next time thanks a lot though

can someone check my work please thanks, oh btw I am still trying to learn how to use LaTeX mathematical typesetting; I figured itll be slightly faster taking a picture of the problem and my work and posting it here so please bare with me :redface: 1. The position of a toy locamotive moving...

lol =P I think my teacher just drew the picture and placed arrows or something. I thank you taking the time and helping me with this problem I really appreciate it heres what I have so far http://ourworld.cs.com/LezardV4leth/13432.jpg can you explain to me what tension is? or is there a...

yes we've done FBD but I think we've only done that with collisions and kinetic energy. I don't recall doing anything with strings besides friction

http://ourworld.cs.com/LezardV4leth/P1010062.JPG theres the picture in the book along with the directions the tension on the string you mean friction?

a small 2 g ball is suspended by a 20 cm string in a uniform electric field of 1.0 x 10 to the fourth power N/C. If the ball is in equilibrium when the string makes a 15 degree angle with the vertical, what is the net charge on the ball? I need someone to check my work for me F=mg (mass...

what is one advantage of transferring energy by electromagnetic waves?

A 25.5 g silver ring (Cp = 234 J/kg times degrees C) is heating to a temperature of 84 degrees C and then placed in a calorimeter containing 5 x 10 to the negative 2 power kg of water at 24 degrees C. the calorimeter is not perfectly insulated, however, a 0.140 kJ of energy is transferred to...

thanks a lot guys I appreciate the help Ill try to figure this out with the info you guys gave me =]

so if n and V are constant that formula would become P over T = R ?

Im not quite sure about the first equation (math isn't my strong point sorry >< )

The pressure in a constant-volume gas thermometer is 7.09x10 to the fifth power Pa at 100.0 degrees celsius and 5.19 x 10 to the fourth power Pa at 0.0 degrees celsius. What is the temperature when the pressure is 4.05x10 to the third power Pa? now I've been told how to do this problem many...
