A rock is launched at a speed of 75 m/s from ground level, at an angle of 30° above the horizontal toward a 17.0 m high wall, which is located 30 m away does the rock clear the wall? If so, by how much? If not, at what height does it hit the wall?

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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 =

use photo math tells u all the answers thats what i use
