I presume you mean ghee as in the butter. Seen as ice is one of the many solids to have a lower density than its liquid form, it freezes from the top. Ghee is made from hydrocarbons not dissimilar to petroleum, it shares the same properties as most elements of its solid state (at 1 atmosphere) being at a higher density than its liquid state.
Answer:
0.78m/s
Explanation:
We are given that
Acceleration=
v=0, s=1 when t=0
We have to find the particle's velocity at s=2m
We know that
By using formula:
Substitute s=2
Hence, the velocity of particle at s=2m=0.78m/s
1 meter up, 1 meter to the left and then 1 metter down.
It goes 1 meter up and 1 meter down, so its in the same place. The only displacement is
1 meter to the left.
