Answer: 760 N
Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.
When Lucy stands on the weighing scale, net force due to gravity is
Hence, weight of Lucy is 760 N
La velocidad correcta de la luz en el vacío es 300.000 km/s .
La distancia = (velocidad) x (duración de tiempo)
Duración de tiempo = 494 segundos, porque cada minuto = 60 segundos
La distancia = (300.000 km/s) x (494 s)
<em>La distancia = 148.200.000 km</em>
N2O is nitrous oxide becuase of the nitrogen and oxygen
The one with the greatest mass would, when everything else is equal. I'm having trouble making out your list of choices.
Answer:
V2 = (V1 - u) / (1 - V1 u / c^2)
V1 = speed of ship in observer frame = .99 c to right
u = speed of frame 2 = -.99 c to left relative to observer
V2 = speed of V1 relative to V2
V2 = (.99 - (-.99 ) / (1 - .99 (-.99)) c
V2 = 1.98 / (1 + .99^2) c = .99995 c
