The sun appears to move across the sky, because the earth spins on its axis. To a person standing on the earth, the sun subtends
Liono4ka [1.6K]

Answer:

128 seconds

Step-by-step explanation:

The sun subtends an angle \theta=9.28\times10^{-3} rad

Angular velocity equation is \omega = \frac{\theta}{t}

where \omega is angular velocity and t is time.

Earth spins at a rate of :

\omega = \frac{2 \pi rad}{24 h \times \frac{3600 s}{1 h}} = 7.27221\times10^{-5}  rad/s

Isolating time (t) from angular velocity equation gives:

\omega = \frac{\theta}{t}

t = \frac{\theta}{\omega}

t = \frac{9.28\times10^{-3}}{7.27221\times10^{-5}}

t = 128 s
