The speed of light is about 300,000 km/s (3×105km/s). If Jupiter is 0.72 light hours from the Sun, how far is this?
2 answers:
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:
Explanation:
speed of light, v = 3 x 10^8 m/s
time = 0.72 hour
distance = velocity x time
distance = 3 x 10^8 x 0.72 x 3600
distance = 7776 x 10^8 m = 7.78 x 10^8 km
Thus, the distance is 7.78 x 10^8 km.

Answer:
Ф = 28.9°
Explanation:
given:
radius (r) = 117m
velocity (v) = 25.1 m/s
required: angle Ф
Ф = inv tan (v² / (r * g)) we know that g = 9.8
Ф = inv tan (25.1² / (117 * 9.8))
Ф = 28.9°
