Homework Statement What is the magnitude of the acceleration of a rising hot-air balloon if the ratio of the air density outside the balloon to that inside is 1.25? Neglect the mass of the balloon fabric, the basket and it contents. I don't know how to do a rho so "p" will be rho for density...

Homework Statement A playground carousel is rotating about its center. The radius of the carousel is 1.5m, its initial angular speed is 3.14 rad/s and its moment of inertia is 125 kg m^2. A 40kg person climbs onto the carousel near its outer edge. What is the angular speed of the carousel...

The problem stated excatly is "Find the equivalent resistance seen by the source in the circuit." Does everything still appear to be the same. A kid in my class said that he was able to match the answers out of the book so I still think I'm missing something =/

Guess I should explain how I simplified the whole circuit now. I combined the 10ohm and 40ohm (in parallel) ... (10)(40)/50 = 8ohm I combined the 8ohm and the 22ohm (in series)... 8+22 = 30ohm I combined the 100ohm the 25ohm and the 30ohm (in parallel)... (1/100)+(1/25)+(1/30)=12ohms I...

Hope this works

EE -- Effective Resistance Homework Statement I don't know how to post schematics so I hope this makes sense. There are four resistors in the circuit. An 18 Ohm resistor is the first resistor out of the 5V voltage source followed by three resistors hooked up in parallel. They have a resistance...
