I asked a question concerning this a while ago, but now it's a little different... A student gets a cart that does not suffer drag. Now, though, the track is not leveled. How can I calculate the angle? The cart is on an inclined plane, then there is a pully, and a load. So...

**Physics**

There is no ramp involved... its just a cart on a flat table, and then a puly, and a load. Would gravity be pulling the load down, which would make the cart move? I still don't get how I would calculate the 'drag' (friction and air resistance) force. Here's my ...

**Physics**

This problem concerns a student that is attempting Newton's 2nd Law, but the cart does not run without friction. How do I calculate the drag force, givin the mass of the cart (7.6kg), the mass of the load (4.2kg), and the resulting acceleration (1.2m/s2)? I'd ...

I have another question concerning (S) & (R) enantiomers of Limonene. How would I compare the physical characteristics of the (R)-(+)-limonene and (S)-(-)-limonene? I guess I don't get how I can determine the physical characteristics of (S) from (R). Would they be the same?

**Chem**

How do I estimate the optical roation of an (S)-enantiomer if I know the optical rotation to the (R)-enantiomer? For instance, for limonene, after conducting an experiment, I got that the optical rotation for the (R)-enantiomer was 10, would the (S) be -10? Any help would be ...
