Question:

Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump?

Disturbed by speeding cars outside his workplace, Nobel laureate Arthur Holly Compton designed a speed bump (called the Holly hump) and had it installed. Suppose a 1 800-kg car passes over a hump in a roadway that follows the arc of a circle of radius 20.2 m. (a) If the car travels at 30.5 km/h what force does the road exert on the car as the car passes the highest point of the hump? magnitude direction (b) What is the maximum speed the car can have without losing contact with the road as it passes this highest point?

Answer:

You can get a new one for around 5 or 6 dollars. If you're loosing sleep over it, just replace it. They're easy to stop - just a tad harder than before. Now they won't close or fit without a 9 volt battery installed, so you have to install a dead one now. Too many people were removing the batteries and not replacing them. Actually, if it is beeping - and even though it went off after it stared beeping - it's likely that is the designed behavior. They would design it to warn you a little bit ahead of time and not when it would stop functioning in 12 hours. You know the battery is fine - how? By pushing the test button on the detector. That only checks that the detector works, which it will - even for a month or two - maybe even 3. After the battery low starts beeping. Buy a brand new name brand 9 volt battery and try that. Miscellaneous: Somebody told me on some A/C ones I have that the 1/2 life of the radioactive element that's used to detect the smoke only lasts so long and (well, yes it would) anyway making it almost useless after 10 years or so. I had another one near the bathroom that beeped whenever someone opened the door after a shower and the steam came out. Wow! A bunch of people here who never inhaled that's for sure! If cigarettes don't set them off, pot smoke sure isn't going to unless you're blowing it right into the detector or it's a party and you can't see across the room for the pot smoke.
Try looking on YouTube for a video walkthrough - you should just be able to walk out the basement door and be able to bypass the ski shed and go to the garden. If you haven't been told about the garden by Dexter (or, I believe, read about it in in the secret room in the library) I don't think you can get there. If you've done both - then solve the tower puzzle and talk to everyone (both on the phone and in person) and explore everywhere. You may simply be missing something. If you can ask Best George for a hint, do so.
