Mass cannot be created nor destroyed as well.
So, energy just goes into other things.
Example: you are born. You have carbon dioxide in your body, (or star dust). When you die, your body releases that gas.
Make sense?
I hope this helps! (:
Respuesta:
340 N/cm²
Explicación:
Paso 1: Información provista
Peso de la estructura (F): 8500 Newton
Area superficial (A): 25 cm²
Paso 2: Calcular la presión (P) ejercida por la estructura de concreto sobre su base
La presión es igual al cociente entre la fuerza ejercida y la superficie sobre la que se aplica.
P = F/A
P = 8500 N / 25 cm² = 340 N/cm²
Answer:
Explanation:
% yields = <u>experimental yields</u> / theoretical yields )x 100%
=( 302 ÷ 320 )x 100% = 94.4 %
% error = 100% - 94.37% 5.64%
or u can use this law :
% error =(theoretical value - experimental value )/ theoretical value) x 100%
( 320 - 302 )/ 320 ) x 100% = 5.64%
