The frequency of a wave increases when the energy increases
Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
Explanation:
Answer:
True
Explanation:
A cation is a positively charged ion, with fewer electrons than protons,
An anion is negatively charged, with more electrons than protons.
<u>D: Half</u>
We know that,
F = m.a, where F is the force, m is the object's mass and a is the acceleration.
In the first case, we observed that a1 = F/m.
In the second case, we observed that the mass has been doubled, so a2 = F/2m .
By the ratio of the two cases, we get
a1/a2 = F/m / F/2m
or, a1/a2 = 2
or, a1 = 2.a2
or, a1/2 = a2
Therefore, the acceleration gets <u>half</u> of it's original measurement.
Answer:
Q1: (a)
so
Q2:
this is the radius in meter
diameter = 2r
in this i don't know which choice is the right answer
Q3:
so
again there is no correct answer
