Rejuvenation occurs when the river’s base level falls (i.e. when sea level falls). This can be a consequence of either a fall in the amount of sea water or the land rising. Incised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to down cut. Hence, 2nd statement is correct.

There are two types of incised meanders, entrenched meanders and ingrown meanders.As they are products of rejuvenation, they are not formed in mature stage of a river

All are correct. Gravitational waves don’t get distorted or altered by interactions with matter as they go through space. gravitational waves have pure information about the objects and events that created them. The Government of India has given approval for the world’s third advanced Laser Interferometer Gravitational Wave Observatory (LIGO-India) to set up in India.

Angle traced by hour hand in 12 hrs. = 360º.

Angle traced by it in  11/3 hrs=  36012*113°=110°

Angle traced by minute hand in 60 min. = 360º.

Angle traced by it in 40 min. =(360/60*40)°=240°

  Required angle (240 - 110)º = 130º.
