    Time needed to reduce charge of a capacitor

    Homework Statement A 20 uF capacitor initially charged to 20 uC is discharged through a 1.0 kOlhms resistor. How long does it take to reduce the capacitor's charge to 8.0 uC? Homework Equations I=dQ/dt The Attempt at a Solution I know that dQ = 12 uC. What I can't figure...

    Finding magnitude of torque on a molecule

    Oh wait, I just realized the answer to part A is zero because they cancel each other out. I was wrong. So the torque tho I'm supposed to use not the net force but the force on the individual atoms? 3.4E-21 I'm still lost...

    Finding magnitude of torque on a molecule

    Homework Statement Molecules of carbon monoxide are permanent electric dipoles due to unequal sharing of electrons between the carbon and oxygen atoms. The figure shows the distance and charges. Suppose a carbon monoxide molecule with a horizontal axis is in a vertical electric field of...

    Comparing Basicity: -OCH3, -OH, -NH2, and Alkyle with Negative Charge

    Homework Statement -OCH3, -OH, -NH2, and the fourth choice is an alkyle, ethyne with a neg charge. the picture shows a triple bond attacked to a hydrogen. Homework Equations The Attempt at a Solution I know that OH is a relatively common base and I thought it was strong, but I...
