A child of mass 51.4 kg sits on the edge of a merry-go-round with radius 2.1 m and moment of inertia 167.739 kg m2 . The merrygo-round rotates with an angular velocity of 1.7 rad/s. The child then walks towards the center of the merry-go-round and stops at a distance 0.819 m from the center. Now what is the angular velocity of the merry-go-round

area of focus

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
