Answer:
68.2 Quadrillion meters
Explanation:
A lightyear is the distance that light travels in one year.
Speed of light is 
So light covers 300,000,000 meters in one second.
One year has 31536000 seconds so , light covers

so 7.2 light years is

so 7.2 light years is
6.82 x 10^(16) meters or
68.2 Quadrillion meters
Answer:
An energy source in which we use to power most powerplants and reactors.
Explanation:
First, light passes through the cornea. It bends the light inward. The light then passes through the pupil. After entering the eye through the pupil, the light passes through the lens. It focuses the light to create an image on the retina. It consists of light receptor cells called rods and cones. The rods and cones send nerve impulses about the image to the brain through the optic nerve. The visual cortex of the brain receives and interprets the information and tells you what you are seeing
Answer:
Explanation:
30 rev/min (2π rad/rev) / (60 s/min) = π rad/s
α = Δω/t = (0 - π)/3 = π/3 rad/s²
θ = ½αt² = ½(π/3)3² = 1.5π radians
θ = 1.5π rad/2π rad/rev = 0.75 rev
Explanation:
The moon is the only natural satellite of the Earth and is fifth largest natural satellite in our solar system. It formed about 4.51 billion years ago.The principal features of the moon that are observable with the unaided eye are the lighter highlands, the dark maria and few large craters such as Tycho.
