Question

listen
look at the image below. about how many hours pass as the earth rotates from the 1 position to the 3 position?
tidal bulge due to inertia
tidal bulge due to gravity
moons gravitational pull
1 hour
6 hours
12 hours
24 hours

Explanation:

Step1: Understand Earth's rotation period

Earth completes a full 360° rotation in 24 hours.

Step2: Calculate rotation per hour

$\frac{360^\circ}{24} = 15^\circ$ per hour.

Step3: Determine angle between positions

Position 1 to 3 is a 180° (half) rotation around Earth.

Step4: Compute time for 180° rotation

$\frac{180^\circ}{15^\circ/\text{hour}} = 12$ hours.

Answer:

12 hours
