We have a diamondback rattlesnake under our house that bit two of my dogs, and almost bit my husband two nights before. We live 50 miles from town so can't get anyone out to remove it for us. How do we trap it or lure it out so we can dispose of it?

A coasting cart has velocities 1.5 m/s, 4 m/s and 11.75 m/s at clock times t = 0 s, 3 s and 6 s. Approximately how far does it move and at what average rate does it accelerate over each of the two time intervals (i.e., 0- 3 seconds and 3 - 6 seconds)?

If the automobile is coasting, and if air resistance is not a significant factor, then over which time interval do you think the average slope of the road is greatest?

ok, i'm 15 and getting ready to turn 16 in september, gonna be a sophomore in high school this year.

ok, well here's how it goes: I called the hospital, got redirected about 4 times to the surgery education department of - i dont even know where - and the person on there said you would have to be 18 to scrub in to the surgery to be an observer - and she was telling me about how it is extremely traumatic, but I really want to see if I'm going to be able to handle it, because i want to go to med school and eventually become a surgeon, and i wanna see if i can handle it NOW, which would be GREAT, or if I'm going to have to expose myself to things a little more. so, she told me that their place "was a separate entity" from my local hospital (which i called originally), so what should i do? I REALLY want to shadow a surgeon, but I'm still stumped how to go about it
