distance to the star Betelgeuse: 640 ly
As we know that
also we know that
So the distance of Betelgeuse = 640 ly
distance to the star VY Canis Majoris:
distance to the galaxy Large Magellanic Cloud: 49976 pc
now we have
distance to Neptune at the farthest: 4.7 billion km
now the order of distance from least to greatest is as following
1. distance to Neptune at the farthest
2. distance of Betelgeuse
3. distance to the star VY Canis Majoris
4. distance to the galaxy Large Magellanic Cloud
Answer:
13.37 rev/min
Explanation:
acceleration due to gravity (g) = 9.8 m/s², centripetal acceleration () = 1.8 * g = 1.8 * 9.8 m/s² = 17.64 m/s².
r = 9 m
Centripetal acceleration () is given by:
The velocity (v) is given by:
v = ωr; where ω is the angular velocity
Hence:
ω = v/r = 12.6 / 9
ω = 1.4 rad/s
ω = 2πN
N = ω/2π = 1.4 / 2π
N = 0.2228 rev/s
N = 13.37 rev/min
Given:
The given value is .
To find:
The value of the given expression by using the Binomial approximation.
Explanation:
We have,
It can be written as:
Therefore, the approximate value of the given expression is 1.0002.
Answer: momentum has the same direction as that of velocity but when 2 bodies with the same linear momentum & different velocities it has different masses because a vector quantity is represented by a cross product of mass and velocity of object .
The answer is diffraction or interference
