Answer:
P = 589 (W)atts
Explanation:
work done = 30.0 kg(9.81)N/kg(10.0) m = 2,943 J
Power is the rate of doing work
P = 2943 J / 5 s = 588.6 J/s

Explanation:
I disagree with my friend because, the primary difference is not in the kind of atoms, rather it is the arrangement of atoms and molecules that distinguishes solids and liquids.
Atoms are closely packed in solid and hence large cohesive forces act between atoms in solids whereas in liquids atoms are at a distance from each other, hence, less cohesive force act between it's atoms. Moreover, due to loose packing in liquids atoms are free to move in space and hence liquids can flow whereas solids cannot.
To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ
sec θ = 1 / cos <span>θ
csc </span>θ = 1 / sin θ<span>
Using these identities:
</span>cot θ ∙ sec θ = (cos θ / sin θ ) (<span> 1 / cos </span><span>θ)
</span>
We can cancel out cos <span>θ, leaving us with
</span>cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc <span>θ</span>
