Consider the figure below. Find the total Coulomb force on a charge of 2.8 nC located at x = 2.7 cm in part (b) of the figure, given that q = 7.4 µC. (Indicate the direction with the sign of your answer.)___ NFind the x-position (between x = 0 cm and x = 14 cm) at which the electric field is zero in part (b) of the figure.___ cm

i don’t know what the answer is i wish i

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

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 =
