Question

3. Density of mercury is Daes 4. One astronomical unit is equal VI answer_1.5×^•11m​

Answer 1

Answer:

Angular diameter θ=1920 ′′ = 601920 =32 ′ We know that 1 ′ = 601 o = 601 × 180π rad∴ θ=32× 60×180π =0.009 radDistance between sun and earth l=1.5×10 11 mLinear diameter d=lθ=1.5×10 11 ×0.009=1.4×10 9 m

Answer 2

Answer:

astronomical system of units.

The astronomical unit (symbol: au,[1][2][3] or au or AU) is a unit of length, roughly the distance from Earth to the Sun and equal to about 150 million kilometres (93 million miles) or ~8 light minutes. The actual distance varies by about 3% as Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once each year. The astronomical unit was originally conceived as the average of Earth's aphelion and perihelion; however, since 2012 it has been defined as exactly 149597870700 m (see below for several conversions).[4]
