The unit for measuring the rate at which light is radiated from a source is B, Lumen. Lumenous flux is the time rate of the flow of light, or the visible energy produced from a certain light source. It is the quantitative measure of brilliance of a light source. The unit we use for this is lumen.
La cinemática permite encontrar la respuesta para la aceleracion del cuerpo en el cañón es:
a = 1,8 10⁶ m/s²
La cinemática estudia el movimiento de los cuerpos, buscando relaciones entre la posicion, la velocidad y la aceleración.
v² = v₀² + 2 a x
Donde v y v₀ son la velocidad actual e inicial, respectivamente, a es la aceleracion y x la distancia recorrida.
Indica que la longitud de cañon es x= 18 m la velocidad de salida es
v= 29000 km/h ( 
) ( 
s) = 8,055,56 m/s.
La velocidad inicial del proyectil es cero.
a = 
a = 
a = 1,8 10⁶ m/s²
En conclusión usando la cinemática podemos encontrarla respuesta para la aceleracion del cuerpo en el cañón es:
a = 1,8 10⁶ m/s²

Answer:
0.89 g/cm^3 = 890 kg/m^3
Explanation:
Cross sectional area of U-tube ( A ) = 1.00 cm^2
volume of oil ( V ) = 5.00 cm^3
change between top surface = 0.550 cm
height of oil = 5 cm ( volume / area )
height of water = 5 - 0.550 = 4.45 cm
pressure at the oil-water junction = Pressure on the second side of the U-tube at same level
Po * g * Hoil = Pw * g * Hwater
Po * 5 = 1 * 4.45
∴ Density of oil ( Po ) = 4.45 / 5 g/cm^3 = 0.89 g/cm^3
