A 200.kg box is being pushed by a 315N force at an angle of 35 from the horizontal. The box comes to a stop after starting at 22m/s. If the box is pushed along a 55m path, find a. The work done on the box by the applied force.
b. The work done on the box by the force of gravity.
c. The work done on the box by friction.
d. The coefficient of kinetic friction between the box and the ground. ​

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 =

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
