James (mass 85.0 kg) and Ramon (mass 69.0 kg) are 20.0 m apart on a frozen pond. Midway between them is a mug of their favorite beverage. They pull on the ends of a light rope stretched between them. Ramon pulls on the rope to give himself a speed of 1.10 m/s. What is James's speed?

v = –0.89m/s.

Explanation:

This problem require the knowledge of conservation of momentum

Given the mass of James and Ramon to be 85kg and 69kg respectively.

Total initial momentum = 0 since James and ramon were both not moving initially.

Ramon has a final momentum = 69.0 * 1.10

James has a final momentum = 85 * vf

85×v + 69×1.10 = 0

85v + 75.9 =

85v = –75.9

v = –75.9/85 = –0.89m/s

spare some change and give it to the poor

explanation:

plz : ((

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 =
