2. Venus - 108 million km
3. Earth - 150 million km
4. Mars - 228 million km
5. Jupiter - 779 million km
6. Saturn - 1.43 billion km
7. Uranus - 2.88 billion km
8. Neptun - It is the most farthest from the Sun, 4.50 billion km
Answer:
D, I think.
Explanation:
I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.
Which material rises from cracks in oceanic crust
-molten rock
Which is the first step in the seafloor spreading process?
-a crack forms in oceanic crust.
those are all right btw, so you can decide if the answer I told you is right or not.
The time it takes for the Moon to rotate once around its axis is equal to the time it takes for the Moon to orbit once around Earth
Answer:
Power = 130 watt
Explanation:
Power is described as the ability to do work, it is also defined as the amount of work in Joules done in a given time in seconds. Mathematically, it is represented as:

In this example, power is calculated as follows:
Work = 39000 J
Time = 5 minutes
converting the time from minutes to seconds:
1 minute = 60 seconds
∴ 5 minutes = 60 × 5 = 300 seconds

N:B the unit for power can also be represented as Joules/seconds or J/s or JS⁻¹
Answer:
The length of cable is 12.5 m
Explanation:
Since, the wrecking ball completes 1 oscillation, in the same time, as it takes for the rock to complete 5 oscillations.
Therefore,
Time Period of Wrecking Ball = 5 (Time Period of Rock)
Since,
Time Period of Pendulum = 2π√(L/g)
Therefore,
2π√(L₁/g) = 5[2π√(L₂/g)]
√L₁ = 5√L₂
Squaring on both sides:
L₁ = 25 L₂
where,
L₁ = Length of Cable = ?
L₂ = Length of string = 0.5 m
Therefore,
L₁ = 25 (0.5 m)
<u>L₁ = 12.5 m</u>
