45. When a space vehicle's boosters separate from it in the upper atmosphere, it is traveling at a maximum speed of 6000. m/s. After separation its mass is 104,328 kg. Calculate the kinetic energy of the vehicle,
6.260 x 108
3.266 x 1010
6.531 x 1010
1.878 x 1012

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

positive reinforcement? ?

grav potential energy

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 =
