a diver exhales a bubble with a volume of 250 mL at a pressure of 2.4 atm and a temperature of 15 degrees celcius. What is the volume of the bubble when it reaches the surface where the pressure is 1.0 atm and the temperature is 27 degrees celcius
For an unknown sample of the experiment, students measure 1602 counts when they first receive their sample and 1317 counts 3.5 minutes later. Calculate the half-life t12 of their sample.
Can anyone just give me an idea on how to go about solving this problem
Use the comparison or limit comparison test to decide if the following series converge. Series from n=1 to infinity of (4-sin n) / ((n^2)+1) and the series from n=1 to infinity of (4-sin n) / ((2^n) +1). For each series which converges, give an approximation of its sum, togeth...

A beam of microwaves with wavelength= 1 mm is incident upon a 9 cm slit. At a distance of 2 m from the slit, what is the approximate width of the slit's image?
Aspirin is prepared by heating salicylic acid, C7H6O3, with acetic anhydride, C4H603. The other product produced is acetic acid, C2H402. C7H6O3+C4H6)3->C9H8O4+C2H4O2 What is the theoretical yield in grams of aspirin, C9H8O4, when 2.00 grams of salicylic acid is heated with ...
Alrighty I have to find two real world sinusoidal functions. I found: 1. A piston in an engine moves up and down in a cylinder. The height, h centimeters, of the piston a t seconds is given by the function: h= 120 sin(πt) + 200. 2. You can find the amplitude of a wave wit...
