If abody droops from height it reach the ground in three second what is hight

44.1m

Explanation:

Let's assume the mass is negligible.

Acceleration due to gravity is 9.8m/s.

Time is 3s.

Use the formula.

Height /distance=ut + 1/2at^2

0 ×3 + 1/2 ×9.8^2

Height = 0+ 1/2×9.8 × 9.8

Height= 44.1m.

In this scinerio, height is the same as distance.

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 =

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
