Considering how the predictions compare to the observations, what does this imply about the mass distributed in the galaxy?

1 answer:

8 0

In a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per c

kiruha [24]

Answer:

$5.23\cdot 10^3 kg/m^3$

Explanation:

The density of the solid is

$d = 5.23\cdot 10^{-6}kg/mm^3$

we want to convert it into kg/m^3. We must note that:

$1 m^3 = 1 m \cdot 1 m \cdot \1m =1000 mm\cdot 1000 mm \cdot 1000 mm=1\cdot 10^9 mm^3$

Therefore, the conversion can be done as follows:

$d=5.23\cdot 10^{-6} \frac{kg}{mm^3} \cdot (1\cdot 10^9 \frac{mm^3}{m^3}) =5.23\cdot 10^3 kg/m^3$

Answer:

Explanation:

As the current carrying wire carries current in south to north direction, the direction of magnetic field is given by the Right hand thumb rule which is in anticlockwise direction so the magnetic compass deflects towards west.
