What is a brachiopod

The brachiopod has a very limited range of motion and remains, for the most part, sessile. The inarticulate brachiopods are not fixed to one location. Instead, they use their specialized muscular pedicles to burrow through sand and other soft sediments. At the distal end of the pedicle a sticky substance is secreted that forms a sand anchor ...

An ideal diesel engine has a compression ratio of 20 and uses air as the working fluid. The state of air at the beginning of the compression process is 95 kPa and 20^ {\circ} \mathrm {C}. 20∘C. If the maximum temperature in the cycle is not to exceed 2200 K, determine (a) the thermal efficiency and (b) the mean effective pressure.Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related.
