An unsuspecting bird is coasting along in an easterly direction at 2.00 mph when a strong wind from the south imparts a constant acceleration of 0.400 m/s2 . if the wind's acceleration lasts for 2.30 s , find the magnitude and direction theta (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. assume that the bird is originally travelling in the x direction and that there are 1609 m in 1 mi .

50 inches should be the resultant vector

power out to power in less than 100%

the maxium height is 34m/s

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 =
