A toy care is at rest until a child pushes it. The mass of the toy car is 3kg. 5 seconds later, the car is moving at a speed of 10m/s. What is the magnitude of the force the child applied?

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

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 =
