The weight of an astronaut plus his space suit on the Moon is only 202 N. How much do they weigh on
Earth? Take the acceleration due to gravity on the Moon to be gm = 1.6 m/s? and the acceleration on Earth
to be g = 9.8 m/s2. Round your answer to two significant figures and include your unit.

the real answer is -190.6

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

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 =
