Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the star
m = Mass of object at a distance r
r = Radius = 25 km
N = 14 rev/s
The gravitational force of will balance the centripetal acceleration
Velocity is given by
The mass of the neutron star is
Answer:
I'm pretty sure it's air pressure.

I think the answer is B. <span>Engineers apply math and science to solve problems. This answer is the most correct and precise among the four answers</span>
Wavelength = (speed) / (frequency)
= (30 m/s) / (60/sec) =
= 0.5 meter .
