Answer:

1. Earth rotates on its axis; this causes us to experience day and night.

2. The speed of light is 186000 miles per second

3. The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.

Answer:

Seasons occur because of the tilt of the earth's axis which is at an angle of 23.5o. As the earth rotates, the sun rays hit different parts of the globe more directly than others... that's why in the UK its Summer when its Winter in Australia ie North/South hemisphere.

Google speed of light for eg mph, km/h etc but the exact figure is 299,792,458 metres per second

A ball is suspended by a lightweight string, as shown in the figure above.
Irina18 [472]

<u>Answer </u>

A. 1 and 2

<u>Explanation </u>

At point 1 we have the highest potential energy and the kinetic energy is zero.

At 2 the potential energy is minimum and the kinetic energy is maximum.

The law of conservation of energy says that energy cannot be created nor destroyed. So, the change in P.E = Change in K.E.

P.E = height × gravity × mass. The height referred here is the perpendicular height. Gravity and mass are constant in this case.

From the diagram it can be seen clearly that the vertical height from 2 to 1 is much greater than from 4 to 3.

This shows that the change in P.E is greater between 1 and 2 and so is kinetic energy.
