Answer:
7.77 x 10⁸ Km
Explanation:
given,
Speed of light = 3 x 10⁵ Km/s
= 3 x 10⁸ m/s
1 light hour = 1.079 x 10⁹ Km
now,
0.72 light hour = 0.72 x 1.079 x 10⁹ Km
= 0.7769 x 10⁹ Km
= 7.77 x 10⁸ Km
The Jupiter is 7.77 x 10⁸ Km far from sun.

Answer:
B
Explanation:
in a liquid the particles are widespread and move around each other but in a solid they move in place and are tightly packed
Answer:
Greater than
Explanation:
Here, angular momentum is conserved.
When the cloud shrinks under the right conditions, a star may be formed.
Thus, Diameter of clouds are much higher than a star.
Moment of inertia of cloud is greater than the star's inertial.
so, angular velocity of the star would be greater than angular velocity of the rotating gas.
Answer:
1.97 * 10^8 m/s
Explanation:
Given that:
n = 1.52
Recall : speed of light (c) = 3 * 10^8 m/s
Speed (v) of light in glass:
v = speed of light / n
v = (3 * 10^8) / 1.52
v = 1.9736 * 10^8
Hence, speed of light in glass :
v = 1.97 * 10^8 m/s
