Answer:
The Kinetic Energy of the guanabana is, K.E = 341.04 J
Explanation:
Given data,
The mass of the guanabana, m = 5.8 kg
The height of the fruit from the ground, h = 6 m
Let the potential energy at the ground be 0
<em>According to the law of conservation of energy, the total energy of a system is conserved.</em>
So, when the guanabana reaches the ground, the P.E is fully converted into K.E
The P.E at height h is
P.E = mgh
= 5.8 x 9.8 x 6
= 341.04 J
At ground 6 m drop,
P.E = K.E
Therefore, the Kinetic Energy of the guanabana is, K.E = 341.04 J
The duck is not carried by the wave motion because <span>Waves move energy through a medium but don't transfer particles. So when the waves pass by a duck floating on a lake, the duck just bobs up and down, but remains in its place.</span>
No. Atom cannot exist without a nucleus. There would be only one part in an atom if nucleus would be deleted and that will be "Electrons", when electrons will be alone they will be just electron not an atom.
In short, Atom can't exist without a nucleus
Hope this helps!
