Answer:
Explanation:
Let c be the circumference and r be the radius 
c = 2πr , r = c / 2π , area A = π r² = π (c/2π )²  = (1/4π) x c² 
flux (ψ) = BA = 1 X 1/4π X c²
dψ/dt = 1/4π x 2c dc/dt =1/2π x c x dc/dt
at t = 8 s 
c = 161 - 13 x 8 = 57 cm , dc/dt = 13 cm/s  
e = dψ/dt = (1 / 2π )x 57 x 13 x 10⁻⁴ = 118 x 10⁻⁴ V.
 
        
             
        
        
        
Answer:
empty space
Explanation:
Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.
Hence, it can be concluded that Most of our Solar system is composed of "Empty Spaces."

The speed of a mechanical wave depends on the mechanical properties 
of the medium through which the wave is traveling.
The speed of an electromagnetic wave depends on the electrical properties 
of the medium through which the wave is traveling.
It's pretty well unanimous for choice <em>A</em> .
