Answer:
Sound needs a medium through which to travel.
Explanation:
In space there is no air or medium. Sound waves need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.
La primera instrucción es verdadera, la segunda es falsa porque dos elementos no pueden tener el mismo número de masa (excepto azufre y argón) Estrictamente hablando, No. Puede tener 2 (o más) elementos con el mismo 'número de masa atómica', lo que significa que el número total de nucleones (neutrones de protones) es el mismo. En el ejemplo dado en una respuesta anterior, el azufre tiene un isótopo con el número de masa atómica 36 (16p 20n) y Argón también tiene un 36 (18p 18n). La tercera declaración es verdadera, si tiene un número diferente de neutrones, entonces es un isótopo. La cuarta declaración es falso. Espero que esto te ayude.
I think it comes from Fungi. I'm not 100% sure about that though.
Experimental errors can be of two kinds: human error and analytical error. Analytical error can be corrected easily. You just have to use instruments that are of high precision. For example, instead of using the platform balance, use the analytical balance which displays 4 decimal places to be highly accurate. For the human error, this is subjective. The only way to correct human error is to be more meticulous on your data measurements.
Answer:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
