Bar oc rotates with a clockwise angular velocity ωoc = 6.0 rad/s. the pin a attached to bar oc engages the straight slot of the sector. determine the angular velocity ω of the sector and the velocity vrel of pin a relative to the sector for the instant represented. the angular velocity is positive if counterclockwise, negative if clockwise. the relative velocity is positive if to the right, negative if to the left.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
