Answer:
Explanation:
Because the spaceships are traveling in the same direction, you should subtract the speed of spaceship A from the speed of spaceship B in order to calculate 
.
Answer is C. when protons are equal to electrons their charges cancel out making it neutral because electrons have a charge of negative one and when you combine them positive 1 and negative 1 is 0.

Answer:
Total time to complete the race = 45 sec
Explanation:
We have given that each lap is 60 m long
Average speed for the first lap = 2 m/sec
So time taken to complete the first lap 
Average speed for second lap = 2 m/sec
So time taken to cover the second lap 
So total time to complete the race = 30 +15 =45 sec
Answer:
La distancia media de Venus al Sol es de 108.159.260,51 Km
La distancia media de la Tierra al Sol: 149.597.870,691 Km
La diferencia entre una y otra distancia media te dará el promedio de distancia de la Tierra a Venus: 41.438.618,181 Km.
Siendo la velocidad de la luz: 299.792,458 Km / seg
Divides: 41.438.618,181 Km / 299.792,458 Km / seg = 138,22433 segundos
138,22433 seg / 60 seg = 2,30374 minutos
Este tiempo es el que tarda la onda de radio en viajar del planeta Venus a la Tierra.
La velocidad de la onda de radio se conviene en considerarla igual al de la velocidad de la Luz en el vacÃo.
