Explanation

21 March and 23sept equal day and night.

The whole earth experiences equal days and equal nights is called an equinox

In Nairobi (Libya) equal day and night happen.

Explanation

Phases of the moon occur because we can see only that part of the moon which reflects light towards us.

The changing shape of the bright part of the Moon that we see is called its phase.

The moon is illuminated because it reflects the light from the sun.

The part of the moon facing the sun is lit up.

The part facing away from the sun is in darkness.

Explanation

Increasing the energy of a sound wave amplifies its amplitude, resulting in a louder sound.

Loudspeakers work by converting electrical energy into sound energy, so higher energy input leads to a louder output.

Explanation

It is a cooling agent that has a lower temperature than water ice and is solid

It is extremely cold, with a temperature of −109 °F (−78 °C).

Explanation

All plants move Anticlockwise around Sun.

All plants move anticlockwise around their axis.

Earth rotates its axis from West to East.

Explanation

• Given: Mass on Earth = 100 kg
• If an object has mass "m "on Earth, the mass would remain the same on the moon.
  • ​So the mass of the object on the moon is 100 kg.

Mistake Points

• The weight of the human on the moon will change and will be 1/6th of the weight on earth because of the moon's weak gravitational impact.
• Weight on Moon = (Mass on Earth) x 1/6
• Weight on Moon = 100 / 6 = 16.7 kg.

Explanation

Explanation

The unit used to measure the latitude of the Earth is degrees (°), which can be broken down into minutes (′) and seconds (″).

The equator is the reference line for latitude.

It is defined as 0° latitude.

It divides the Earth into the Northern and Southern Hemispheres.
