Hi Phoebe, I'm Sasha and I'm also 12 years old and here's the answer your looking for
Answer:
Particles are, by their very nature, attracted to particles with an opposite charge, and they repel other similarly charged particles. This prevents electrons from ever coming in direct contact (in an atomic sense and literal sense). Their wave packets, on the other hand, can overlap, but never touch.
As we know that the conductance is given by the formula
now here we know that
L = length
now we know that conductance will remain constant while the length is quadrupled
so here we have
so here radius becomes double
so correct answer will be
<em></em>
The atomic mass. By taking two different types of the same element and calculating the average based on the amount of each type in the world, you get the basic atomic difference.
Answer:
1039.23 m/s
Explanation:
Given:
Height, H = 3 x 10⁵m
acceleration of gravity on lo, a = 1.80 m/s² toward moon's surface i.e -1.80m/s² with respect to the earth
Now, at its highest point the velocity i.e the final velocity 'v' = 0m/s.
Now using the Newton's equation of motion
v² - u² =2as
where,
v = final velocity
u = initial velocity
a = acceleration
s = distance
now,
substituting the values we get
0²-u² = 2 × (-1.80) × 3 x 10⁵
or
Hence, the <u>initial velocity</u><u> with which the material is ejected is </u><u>1039.23 m/s</u>
Answer:
the change in potential energy is proportional to the displacement from the equilibrium position.
Explanation:
Simple Harmonic Motion is said to occur when an object is oscillating around a particular position where is it in equilibrium by a force with the following features:
The force has to be directed towards the equilibrium position and secondly, the magnitude of the force is proportional to the displacement from the equilibrium position of the object.
