A barge ﬂoating in fresh water (p = 1000 kg/m3) is shaped like a hollow rectangular prism with base area A = 550 m2 and height H

Karolina [17]

Answer:

a) $\Delta m = 330000\,kg$ , b) $h = 1.268\,m$

Explanation:

a) According the Archimedes' Principle, the buoyancy force is equal to the displaced weight of surrounding liquid. The mass of the coal in the barge is:

$\Delta m \cdot g = \rho_{w}\cdot g \cdot \Delta V$

$\Delta m = \rho_{w}\cdot \Delta V$

$\Delta m = \left(1000\,\frac{kg}{m^{3}} \right)\cdot (550\,m^{2})\cdot (1.05\,m-0.45\,m)$

$\Delta m = 330000\,kg$

b) The submersion height is found by using the equation derived previously:

$\Delta m = \rho_{w}\cdot \Delta V$

$450000\,kg = \left(1000\,\frac{kg}{m^{3}}\right)\cdot (550\,m^{2})\cdot (h-0.45\,m)$

The final submersion height is:

$h = 1.268\,m$

¿Qué diferencia una magnitud fundamental de una derivada?

artcher [175]

Answer:

Explanation:

Una magnitud fundamental es aquella que se define por si misma y es independiente de las demás (masa, tiempo, longitud, etc.). magnitud derivada. Una magnitud derivada es aquella que se obtiene mediante expresiones matemáticas a partir de las magnitudes fundamentales (densidad, superficie, velocidad).

The age of the universe is thought to be about 14 billion years. Assuming two significant figures, write this in powers of ten i

ira [324]

A ) 14 billion years = 14,000,000,000
$1.4 * 10^{10}$
b ) 1 year = 365 · 24 · 3,600 = 31,536 · 10³
$1.4 * 10 ^{10}*3.1536 * 10^{7} =4.4 * 10 ^{17}$
