Ohhhh oops, I forgot to add the voltage from the battery... This isn't intuitive to me at all. So Δ5 across the 2Ω resistor is 10V. 9V - 10V = -1 V -1 V / 3 Ω = -1/3 A Thank you so much!

Okay. I'm still unsure of how to do this. I split the circuit into the loop on the left. Using the fact that the current through the 2ohm resistor is 5A, I found that the change in potential at this point is 10V. I know that the total change in potential must be 0, so the change in potential...

Homework Statement The ammeter reads 5.0A. Find I1, I2, and ε Homework Equations ΔV=IR The Attempt at a Solution I've never dealt with ammeters before so I'm very confused. To start, I tried breaking this into loops, and then used Kirchhoff's Law. I started with the left side, since I...

I did draw a free body diagram and I believe my trig relations are correct. After further digging I found nearly the exact same question http://courseweb.stthomas.edu/physics/academics/111/Brita/Spring%202012/Unit%202/GP6%20P11%20S12.pdf but when I calculate the velocity with their numbers I...

Homework Statement You are passing a construction site on the way to physics class, and stop to watch for a while. The construction workers appear to be going on a coffee break, and have left a large concrete block resting at the top of a wooden ramp connecting one of the building's upper...

Ohhh that makes sense, thank you so much!

Homework Statement A student holds a book at rest on the palm of her hand. She lifts the book straight up, bringing it to rest again at a higher point. 1. Is the net work done on the book positive, negative, or zero? 2. Is the change in the gravitational potential energy positive, negative...

Homework Statement Two bicycle tires are set rolling with the same initial speed of 3.30m/s along a long, straight road, and the distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 psi and goes a distance of 17.3m ; the other is at 105...

For my homework I was given a velocity diagram of the Juan de Fuca plate similar to this: The first question is as follows: Measurements indicate that the Juan de Fuca plate is moving at a speed of ~40 mm/year. Calculate, and draw diagrams that show, the horizontal and vertical components...
