13. Please explain the answer Below is an exaggerated view of the Earth's elliptical orbit about the sun. As it moves from point A to point B, whichof the following is true about its speed and angular momentum?AO The speed decreases and the angular momentum remains constant.The speed and angular momentum remain constant.The speed increases and the angular momentum increases .The speed decreases and the angular momentum decreases.O The speed increases and the angular momentum remains constant.B

We know that As the earth orbits around the sun, the angular momentum is conserved & the areal velocity remains constant. Here A is the Apogee & B is the Perigee & the corresponding velocity at the locations A & B be VA & VB respectively. Also, The distance of the sun from A & B be RA & RB respectively. From Angular momentum conservation we can say that, mVARA = mVBRB or VARA = VBRB ;Since from the above figure we can clearly see that RB > RA this implies that VA > VB (velocity at A is greater than velocity at B) Finally we can conclude that the speed decreases as the earth moves from A to B & the angular remains constant thus option-1 is the correct choice.
