Bill is farsighted and has a near point located 119 cm from his eyes. Anne is also farsighted, but her near point is 70.0 cm fro
Gennadij [26K]

Answer:

Explanation:

For Bill's glasses)

d_o=25 cm-2 cm=23.2 cm

d_i=129 cm-2 cm=127 cm

We know that

1 / f = 1 / d_o + 1 / d_i


f=(1 / d_o + 1 / d_i)^-1


so plug the numbers in

f = (1 / (23) + 1 / (127))^-1


= 28.08 cm

For Anna's glasses)

d_o=25 cm-2 cm=23 cm

d_i=70.0 cm-2 cm=68 cm

Same thing

(1 / f = 1 / d_o + 1 / d_i
)

f=(1 / do + 1 / di)^-1


so plug the numbers in

f = (1 / (23) + 1 / (68))^-1


= 17.21 cm

What does the term electron orbital describe? What does the term electron orbital describe? An electron orbital describes a thre
Yuliya22 [10]

Answer:

An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

According to Heisenberg's theory we cannot observe the position and velocity of an electron in an orbit, but if they were around the nucleus (in orbit), it would be possible to know its velocity and position, which would be contrary to the principle of Heisenberg So we can say that no electron revolves around a certain orbit around the nucleus, so we can only predict if the electron will be in the right position at the right time.

From there we find two definitions for electron orbital let's see:

  • Orbital is considered the region of space, where each electron spends most of its time.
  • Orbital is considered the region of space that is most likely to find an electron.
