The x component of a velocity vector that has an angle of 37° (to the +x) has a magnitude of 4.8 m/s. what is the magnitude of the velocity? what is the y component of the velocity?

Magnitude of velocity V = 6.015 m/sec

Y component of velocity = 3.61 m/sec

Explanation:

We have given magnitude of velocity in x direction, that is horizontal component

Angle with x axis = 37°

We know that horizontal component

So

Y component of velocity is given by

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 =
