You are in a spaceship (mass m) orbiting earth in a circular orbit at radius r. you need to complete a spacewalk to investigate possible damage on the ship from collision with debris in orbit. your intention is to tether yourself to the ship with a cord of length l, such that the cord is taut and the ship is between you and the earth (this way, you can get a good look at the damage). you have a mass of m. we will find an expression for the minimum tension needed to keep you tethered to the ship. (a) write f = ma for the ship. write f = ma for you while on your spacewalk (b) given that you and the ship both orbit the earth in the same time period, find a relation between your linear speed and the ship's. (c) find an expression for the tension in terms of the variables given. (d) (optional) simplify the result under the assumptions that i

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

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 =
