Draw and label a diagram and show your work for the following: A 2.75 x 10^3 kg car is parked on a hill on a 18.0° incline. A 2.25 x 10^4 N frictional force holds the car in place. Find the coefficient of static friction.​

photocells convert light energy to electricity

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the components of a vector are the parts of the vectors that are to each other.

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 =
