11. An object accelerates 7.2 m/s2 when a force of 4.0 newtons is applied to it. What is the mass of the object?

The surface area of a sphere can be found using the formula SA=4(x)pi(x)R squared. Middleton Middle School wants to paint kickballs purple for their carnival. The kickballs are all the same size. They used 6923.7 inches

x=times

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 =
