I have an astronomy question... Spinning up the solar nebula. The orbital speed of the material in the solar nebula at Pluto's a
attashe74 [19]
<span>The angular momentum of a particle in orbit is 

l = m v r 

Assuming that no torques act and that angular momentum is conserved then if we compare two epochs "1" and "2" 

m_1 v_1 r_1 = m_2 v_2 r_2 

Assuming that the mass did not change, conservation of angular momentum demands that 

v_1 r_1 = v_2 r_2 

or 

v1 = v_2 (r_2/r_1) 

Setting r_1 = 40,000 AU and v_2 = 5 km/s and r_2 = 39 AU (appropriate for Pluto's orbit) we have 

v_2 = 5 km/s (39 AU /40,000 AU) = 4.875E-3 km/s

Therefore, </span> the orbital speed of this material when it was 40,000 AU from the sun is <span>4.875E-3 km/s.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

A 250 kg car has 6875 kg•m/s of momentum. What is it’s velocity?
liraira [26]

Answer:

v = 27.5 m/s

Explanation:

p = m × v

6,875 = 250 × v

250v = 6,875

v = 6,875/250

v = 27.5 m/s

A rat is running around a track. The rat ran a total 1400 m in 16 minutes. What is the rats average speed in m/s?
ololo11 [35]

Answer:

v = 1.5 m/s

Explanation:

Given that,

Distance covered by a rat, d = 1400 m

Time, t = 16 minutes = 960 s

We need to find the average speed of the rat. The speed of an object is given by :

v=\dfrac{d}{t}\\\\v=\dfrac{1400\ m}{960\ s}\\\\v=1.45\ m/s

or

v = 1.5 m/s

So, the average speed of the rat is 1.5 m/s.
