Sobre un plano inclinado que forma 37° con la horizontal, se encuentra un bloque A, de masa 6 , unido por medio de una cuerda a otro bloque B, de masa 3 que cuelga de la cuerda, la cual pasa por una polea situada en la parte inferior del plano. Si el coeficiente de rozamiento entre el bloque y el plano es = 0.4, calcular la aceleración del sistema y la tensión del hilo.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

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 =

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
