The space between them is shrinking at (60+40)= 100 mph. It started out being 120 miles. To shrink to zero will take
(120 miles) / (100 mph) = 1.2 hours
That's 1 hour and 12 minutes.
While self-gravity pulls the star inward and tries to make it collapse, thermal pressure (heat created by fusion) pushes outward. These two forces cancel each other out in a main sequence star, thus making it stable.
Answer:
Transverse wave
Explanation:
Its because in transverse wave the particle displacement is perpendicular to the direction of wave propagation..hope it helps you...
Answer:
12 cm/s
