Electrons are added into the outermost what in groups 1 & 2
aivan3 [116]

S orbital.

Group 1 elements have a general configuration ns^{1}, where n represents the highest occupied Principal Energy Level. For example, Lithium has the valence configuration 2s^{1} whereas Cesium has 6s^{1}. Both of them belong to Group 1 of Periodic Table.

Group 2 elements have a general configuration of ns^{2}. For example, Magnesium has 3s^{2} as its outer shell configuration while Strontium has the same as 5s^{2}.

We see that in both the cases, the outermost S orbital is being filled.

A tightrope walker more easily balances on a tightwire if his pole
cestrela7 [59]
B) droops.

Why?
To maintain balance, you do not need something short so you're balanced well... You need something long and droopy to maintain balance. The pole should be held by your waist and it should be light.

Hope this helps!~

Which electromagnet will produce the strongest magnetic force? (1 point)
Contact [7]

Answer:

Y

Explanation:

Y will produce the strongest magnetic force because the current intensity is medium and it has 50 turns in the wire. the number of turns will increase the force because the magnetic field will be more concentrated.

Have a great day :)

The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of
lidiya [134]

Answer:

The velocity of the tuning fork sound is 317.4648 m/s

Explanation:

The given parameters are;

The frequency of the fork, f = 426.7 Hz

The length of the closed air column, L = 0.186 m

The diameter of the tube, d = 0.15 m

At the fundamental frequency in a closed tube, we have;

λ = 4·L

Where;

λ = The wavelength of the wave

L = The length of the tube

From the equation for the velocity of a wave, we have;

v = f·λ

Where;

v = The velocity of the (sound) wave

f = The frequency of the wave = 426.7 Hz

λ = 4·L = 4 × 0.186 m = 0.744 m

∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s

Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s
