Warm, moist air increasing ocean temp
Wavelength = (speed) / (frequency) = (460 m/s) / (230/sec) = <em>2 meters</em>
Gravitational potential energy =
(mass) x (gravity) x (height)
= (5.8 kg) x (9.8 m/s²) x (2.5 m)
= 142.1 Joules (C)
Answer:
A
Explanation:
Begin as protostars, which fire up when they collapse and become denser and hotter.
