Find the average power Pavg created by the force F in terms of the average speed vavg of the sled.

Complete Question

The power created  is  

Explanation:

From the question we are told that

    The that the average power is  mathematically represented as

Where W is  is the Workdone which is  mathematically represented as

      Where F is  the applies force and  s  is the displacement  due to the force  

        So  

Now this  displacement can be represented mathematically as  

Where is the average  velocity and is the time  taken  

So  

=>        

Pavg =  Fvavg

Explanation:

Since the P (power) done by the F (force) is:

P = Fs/t

and we are looking for the velocity, so then it would be:

P = Fv

with the average velocity the answer is:

Pavg =  Favg

If an object is moving at a constant speed, and the force F is also constant, this formula can be used to find the average power. If v  is changing, the formula can be used to find the instantaneous power at any given moment (with the quantity v in this case meaning the instantaneous velocity, of course).

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

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 =
