A570-g squirrel with a surface area of 880 cm2 falls from a 5.2-m tree to the ground. estimate its terminal velocity. (use the drag coefficient for a horizontal skydiver. assume that the cross-sectional area of the squirrel can be approximated as a rectangle of width 11.2 cm and length 22.4 cm. note, the squirrel may not reach terminal velocity by the time it hits the ground. give the squirrel's terminal velocity, not it's velocity as it hits the ground.)

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

The first law of thermodynamics is as follows: ∆u=q-w , which means in a system is equal to added, minus done by the system. the units for these variables are in .
