What quantities determine how quickly a wave travels along a string? choose all that apply..a)mass of the stringb)length of the stringc)tension in the stringd)linear density of the string

a)Mass of the string

b)Length of the string

c)Tension in the string

d)Linear density of the string

Explanation:

The speed of a wave on a string is given by:

where

T is the tension in the string

m is the mass of the string

L is the length of the string

m/L is the linear density of the string

Looking at the formula, we notice that the speed of the wave, v, depends on all the following quantities:

a)Mass of the string

b)Length of the string

c)Tension in the string

d)Linear density of the string

a and c

c is 100% but i am confused in a

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 =
