A horizontal disk with a radius of 7 m rotates about a vertical axis through its center. The disk starts from rest and has a constant angular acceleration of 1.7 rad/s 2 . At what time will the radial and tangential components of the linear acceleration of a point on the rim of the disk be equal in magnitude? Answer in units of s.

where is the photo and the answer choices?

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 =
