How much does a cloud weigh? Usgs.gov says that the average cumulus cloud (the big fluffy white ones) weighs 500,000 kilograms. Convert that number to pounds. Then put that value into a perspective you can visualize, such as comparing it to other objects you are familiar with. Show all your math. Do not just look up the value.

At what depth under water is the pressure twice atmospheric pressure? Given your result, a diving watch labeled100m (indicating depth due to pressure under water it can tolerate) could also be labeled in terms of atomospheres.They do this. It might say 5ATM. What label could this watch have instead of "100m"?

The Weather Monitor. Your South American expedition splits into two groups: one that stays at home base, and yours that goes off to set up a sensor that will monitor precipitation, temperature, and sunlight through the upcoming winter. The sensor must link up to a central communications system at base camp that simultaneously uploads the data from numerous sensors to a satellite. In order to set up and calibrate the sensor, you will have to communicate with base camp to give them specific location information. Unfortunately, the group's communication and navigation equipment has dwindled to walkie-talkies and a compass due to a river-raft mishap, which means your group must not exceed the range of the walkie-talkies (3.0 miles). However, you do have a laser rangefinder to help you measure distances as you navigate with the compass. After a few hours of hiking, you find the perfect plateau on which to mount the sensor. You have carefully mapped your path from base camp around lakes and…
