Given that,
Eccentricity = 0.0086
Suppose, The length of half of the major axis is
We need to calculate the distance from the center to the foci
Using formula of eccentricity
Where, e = eccentricity
a = major axis
c = the distance from the center to the foci
Put the value in to the formula
We need to calculate the perihelion distance of Neptune from the sun
Using formula of distance
Put the value into the formula
Hence, The perihelion distance of Neptune from the sun is 991400000 km.
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of
Initial velocity of (opposite direction)
Final velocity of (same direction )
Final velocity of (same direction)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
Had to look for the options and here is my answer.
Based on the listed choices, the one that is considered as a disadvantage of radio telescopes over optical telescopes is that "t<span>hey have greater resolution for similar size collectors." Hope this answers your question.</span>
