Explanation:
Answer:
Procyon appears brighter in the sky
Explanation:
Apparent magnitude of star Antares = 1.0
Apparent magnitude of star Procyon = 0.4
Pogson's Ratio
m₂-m₁ = -2.50 log(B₂/B₁)
where, m is the apparent magnitude
B = Brightness of star or flux coming towards us (W/m²)
∴Larger magnitudes correspond to fainter stars so here 1>0.4 which means Antares appears dimmer and Procyon appears brighter.
The output force is
<em>F = (input force) x (3.14) / (area of the </em><u><em>small</em></u><em> cylinder's piston)</em>
