In nascar, the race cars move through banked turns. if a car with mass m is traveling in a circle on a road that has an incline of theta with respect to the horizontal like these banked turns and the radius of the circle is the speed of the car is and the coefficient of static friction is , derive the expressions for the maximum and minimum angles that the incline can be without the car sliding up or down in terms of, and you must define the x-axis to be along the slope and the y-axis to be perpendicular to the slope as well as showing your work.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

i think the answer is a, hope this : )

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 =
