The amplitude of oscillations has no effect on their time period.
Answer:
radius r is 0.414 R
Explanation:
Given data
FCC octahedral site
atomic radius R
to find out
radius r
solution
we know that at FCC octahedral
length of side = 2 R + 2r
and by pythagorean theorem
a = 2√2R
here a = 2R + 2r
so 2R + 2r = 2√2R
so r = ( √2R )- R
r = 0.414 R
so radius r is 0.414 R
Strong nuclear force is most like electrical force because they are both related to distance statement best describes the similarities between fundamental forces.
<u>Option: D</u>
<u>Explanation:</u>
There are four forms of fundamental forces in nature. They are called gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Strong nuclear force is a spin-dependent, charging-independent force that arises into being due to the mutual association of gluons binding protons and neutrons.
It is also hundred times more powerful than electromagnetic force. Poor nuclear capability comes into being during radio-active decay. This force is due to the interaction of 'w' and 'z' bosons (particles such as protons and neutrons with integral or zero spin) that are heavier in nature. The function of this force is to turn protons into neutrons and vice versa.
I took the test, its constructive interference
Edit: this is kind of a trick question. took the test again it was the same question yet this time the answer was destructive. Good luck with that
Answer:
G
Explanation
The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.
Answer G: speed=v, distance =d.
