Aspherical protein of molar mass 4.5x100 g/mol and density 1.33x10 kg/m3 is placed at the top of a 2-cm-long centrifuge tube filled with a fluid of density 1.1x103 kg/m3 and viscosity of 1.8x10 pa-s. in the centrifuge, the sample is placed at a distance 20 cm from the rotation axis, and the centrifuge is then run at 3000 revolutions per second (i. e. 3000 hz). a) what is the diameter of these proteins? b) what is the terminal speed of these proteins under centrifugation? c) approximately how long will it take the proteins to sediment to the bottom of the tube?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

measuring things 1 litre of water

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
