Acar of mass 960kg is free-wheeling down an incline at a constant speed of 9.0 m/s. the slope makes an angle of 15 degrees. deduce that the average resistive force acting on the car is 2.4*10^3 n.

a sonic boom is a loud boom that breaks the sound barrier

explanation:

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 =

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
