-- The kinetic energy it has when it hits the ground is exactly
the potential energy it had just before you dropped it.
-- So if you want it to have twice as much kinetic energy at the bottom,
you want it to have twice as much potential energy at the top.
-- Potential energy = (mass)·(gravity)·(height).
The only one of those things that you can change is the height.
Looking at that equation, you can see that if you change the height,
the potential energy changes by the same factor.
So if you want the pebble to have twice as much potential energy,
you have to drop it from twice the original height. (2h)
Conductors (something that allows electricity to flow easily) allow for electricity to flow easily. This would be the wires. If you don't have conductors, then you cannot have electricity flow.
Insulators (something that doesn't allow electricity to flow through it) is important because it allows us to be able to touch the cables or place them next to one another and not shock ourselves
Hope this helps
Work is obtained by multiplying the force and the object's displacement. The force and displacement and force should be in the same direction in order to have work.
W = F x d
d = W / F
Substituting the known values,
d = 352 J / 45 N = 7.82 m
Thus, the displacement of the student is 7.82 m.
That n2 = 2*n1. That is, the index of refraction is twice as big in medium 2 since v=c/n
The change or mutation in a segment of DNA after replication may lead to changes in the genotype, the traits of the organism and the proteins (option i, ii and iii).
<h3>What is a genetic mutation?</h3>
A genetic mutation is any change in the nucleotide bases of the genome of an organism that may be associated with modifications in the phenotypic traits or features of the organism if this change alters the expression of a given gene that produces a particular protein.
Mutations may be neutral when they don't show an apparent effect on the phenotype of an organism such as occur in mutations located in intergenic regions.
Therefore, with this data, we can see that a genetic mutation may alter the proteins produced by an organism which has a direct effect on the phenotype by altering the structures that it is able to synthesize.
