Aplane comes out of a power dive, turning upward in a curve whose center of curvature is 1300 m above the plane. the plane's speed is 260 m/s.
a. calculate the upward force of the seat cushion on the 100 kg pilot of the plane.
b. calculate the upward force on a 90.0 g sample of blood in the pilot's head.

technology is the application of the knowledge gained by science.

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

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 =
