Answer:
Explanation:
The atomic number tells you how many protons are in an element. Each element has a different number of protons, so a specific number of protons will also help you easily identify that particular element. For example, if you are given that an element has an atomic number of 1, you would know the element is hydrogen because other elements have different amounts of protons and thus different atomic numbers.
Im not sure what the answer is unless you put the options up for the multiple choice
Answer:
I think it would be a solution..
But I'm not sure.
I think that because you said before before blending.
Answer:
The maximum potential energy of the child will be maximum at the two end points.
The maximum kinetic energy of the <em>child </em>occurs at the lowest point of the swing.
The potential energy of the child depends on the displacement of the child.
P.E = mgh
The maximum height attained occurs at the two end points of her swing motion.
Thus, the maximum potential energy of the child will be maximum at the two end points.
The kinetic energy of the child depends on the velocity of the child
K.E = ¹/₂mv²
The maximum velocity of the swing occurs at the lowest point of the swing.
Thus, the maximum kinetic energy of the child occurs at the lowest point of the swing.
Hope this helps!
