Answer: The correct answer is "node".

Explanation:

Stationary wave: It is also called standing wave. When two waves of equal frequency or wavelength travelling in opposite direction then the standing wave will form.

These are those wave which do not appear to move but there is an oscillation up and down in same phase.

Anti node: It is the location in the wave where the amplitude is minimum or there is no displacement from the rest position.

Node: It is the location in the wave where the amplitude is maximum or there is maximum displacement from the rest position.

Therefore, At the node of a standing wave, there is no displacement from the rest position.

I believe the answer is node, but I'm not totally sure.

Answer:

Explanation:

Given

radius of electron $(r)=5.3\times 10^{-11} m$

centripetal acceleration $(a_c)=9\times 10^22 m/s^2$

we know

$a_c=\frac{v^2}{r}$

$v=\sqrt{r\times a_c}$

$v=\sqrt{5.3\times 10^{-11}\times 9\times 10^{22}}$

$v=\sqrt{47.7\times 10^11}$

$v=21.84\times 10^5 m/s$

(b)For n=10

$r=100\times 5.3\times 10^{-11} m\approx 5.3\times 10^{-9} m$

$a_c=10^4\times 9\times 10^{22} m/s^2$

$a_c=9\times 10^{26} m/s^2$

$v=\sqrt{r\times a_c}$

$v=\sqrt{9\times 10^{26}\times 5.3\times 10^{-9}}$

$v=21.84\times 10^8 m/s$

Just learned this in chemistry. There are no subscripts, therefor each element only has 1 atom. Na has 1, O has 1 and H has one. There are 3 atoms.

If you cannot get a chair to move across the floor, it is because ___ friction opposes your push.

denis-greek [22]

If you cannot get a chair to move across the floor, it is because static friction opposes your push. When you say static or kinetic friction the two object that facing each other are opposing each other. That's why you're having a hard time pushing the chair.

A very long straight current-carrying wire produces a magnetic field of 25 µT at a distance d from the wire. How far will the ma

daser333 [38]

The magnetic field strength of a very long current-carrying wire is proportional to the inverse of the distance from the wire. The farther you go from the wire, the weaker the magnetic field becomes.

B ∝ 1/d

B = magnetic field strength, d = distance from wire

Calculate the scaling factor for d required to change B from 25μT to 2.8μT:

2.8μT/25μT = 1/k

k = 8.9

You must go to a distance of 8.9d to observe a magnetic field strength of 2.8μT
