The three eons of precambrian time i.e hadean eon ,Archean eon and proyerozoic eon change earth's surface during Precambrian time.
Answer:
Explanation:
When beam is balanced and not rotating with Suki standing on it , let reaction force on the supports be R₁ and R₂. Then
R₁ +R₂ = 336 + 590
= 929
Now the moment beam begins to tip , reaction on distant support R₁ = 0
only R₂ will exists on the support near to Suki.
Taking torque about this support of weight of beam acting from the middle point and weight of suki of 590N ,who is x distance from the support towards the other end.
336 x 1.5 = 590 x
x = .85 m
ie , from second support , Suki can not go beyond a distance of .85 m towards the second end.
Answer: Glands
Explanation: Glands are the structures of the endocrine system that produce and secrete hormones.
