Answer:
Weight of object on moon is 5N ,as we know. Weight of object on moon is 1/3 the of object on earth,so
let weight of object on earth = X
5N= X/3
X = 3×5 = 15N
Hence the weight of the object on earth will
be 15N
Answer:
variable
Explanation:
Globular clusters is defined as collection of numerous star that revolve around the galaxy core. they are so bound to each other that they formed spherical shape. This boundness among the star is due to gravity. The main characteristics of globular cluster is that they contain high density of star at center.
Every galaxy consist of various number of globular cluster and even milky way consist of 125 to 200 cluster

Answer:
Both the rocks land together.
Explanation:
Given:
initial speed of Jan,
initial speed of Len,
direction of velocity by Jan with respect to vertical down direction,
direction of velocity by Len with respect to vertical down direction,
Now velocity of the rock by Len in the vertically downward direction:
Form the equation of motion:
where:
height covered by the object
initial velocity of the object
acceleration due to gravity
time taken by the object to fall the height
Since the velocity of both the rocks is same in the vertical direction are thrown form the same height therefore both of the rocks will land together.
