Answer: 140
Explanation: just multiply 7 x 20
<u>Answer:</u>
The amount of the lighted side of the moon you can see is the same during "how much of the sunlit side of the moon faces Earth".
<u>Explanation:</u>
The Moon is in sequential rotation with Earth, and thus displays the Sun, the close side, always on the same side. Thanks to libration, Earth can display slightly greater than half (nearly 59 per cent) of the entire lunar surface.
The side of the Moon facing Earth is considered the near side, and the far side is called the reverse. The far side is often referred to as the "dark side" inaccurately but it is actually highlighted as often as the near side: once every 29.5 Earth days. During the New Moon the near side becomes blurred.

Answer:
100 percent
Explanation:
Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative humidity very rarely falls below 30 percent.
The direction of the curl of magnetic field is determined by right hand thumb rule. Suppose you are holding a current carrying wire in your right hand such that the direction in which your thumb points is the direction of the current in the that wire then the fingers curled will determine the direction of the magnetic field. In B, the direction of current in the wire is towards ourself. Now, use right hand rule such that the thumb points towards yourself. The curled fingers rotate clockwise. Therefore, the magnetic field is in anti-clock direction
