The pressure and temperature at the beginning of compression of an air-standard diesel cycle are 95 kpa and 300 k, respectively. at the end of the heat addition, the pressure is 7.2 mpa and the temperature is 2150 k. determine (a) the compression ratio. (b) the cutoff ratio. (c) the thermal efficiency of the cycle. (d) the mean effective pressure, in kpa.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
