La respuesta correcta es Masa
Explicación:
Todos los objetos existentes en el universo se componen de materia cuya unidad básica es conocida como átomo. A su vez el átomo se compone de subpartículas que incluyen protones, neutrones y electrones. Además de esto, la cantidad de materia o átomos en un objeto o cuerpo, por ejemplo la cantidad de materia en un balón se conoce como masa. Este factor se mide en unidades como gramos o kilos, por ejemplo, la cantidad de masa en una manzana es de aproximadamente de 150 gr. Finalmente, la masa se diferencia del peso porque en el peso la fuerza gravitacional y no solamente la materia se debe considerar.
Answer:
the statement is TRUE
Explanation:
When we move in the same direction, the relative speed of the two vehicles is lower, so we must subtract their speeds, if the result is positive the vehicles approach and if it is negative they move away.
v_relative = v₁ - v₂
When the two vehicles go in opposite directions, the speed is much higher, so we must add their speeds
v_relative = v₁ - (-v₂))
v_relative = v₁ + v₂
therefore the statement is TRUE
there are three picture with example and sentence
Light year is the distance traveled by light in 1 year of time interval
so here we can say that the statement must have used the word light year as the distance
so we have
A) It's about 4 light-years from here to Alpha Century.
this shows the distance between two so it is correct
B) It will take me light-years to complete this homework assignment.
here it represent the light year as time so it is INCORRECT
C) A light-year is about 10 trillion kilometers.
This shows the distance so it is correct
D) It will take the Voyager spacecraft about 20,000 years to travel just 1 light-year.
It shows the distance so it is correct
E) The Milky Way Galaxy is about 100,000 light-years in diameter.
this is distance so it is also correct
