Answer:
2.2386 m/s
Explanation:
I think you would use the momentum equation.
m1v1=m2v2
m1= mass of the bag (8.5kg)
v1= speed of bag (6.9 m/s)
m2= mass of bag and cart (26.2 kg)
v2= speed of cart and bag
Plug these numbers all into the equation and you solve for v2 which ends up at 2.2386 m/s
I am going to say velocity because you have the same amount of acceleration going in a certain direction.
I think the correct answer is the third statement, electron from escaping from the tube containing the triode. The negative charge on the grid repels any electron in the tube. As a result,the flow of current is controlled. If the field is that strong, all current flow will stop resulting to maintaining the electron cloud in the tube.
-B because metal hardly breaks but non metal items such as glass or plastic does!
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>
