The energy levels are also called principal levels. The number of sublevels in the third energy level is three.

<h3>What is energy level?</h3>

The Energy levels are at a fixed distance from the nucleus of an atom, where electrons are arranged in shells.

In the third energy shell, electrons are present. The third principal energy level has three sublevels, s, p and d.

The number of sublevels in the third energy level is three.

Three deer, a, b, and c, are grazing in a field. deer b is located 62.1 m from deer a at an angle of 54.3 ° north of west. deer

sveticcg [70]

by cosine law we know that

$c^2 = a^2 + b^2 - 2 abcos\theta$

$\theta = 180 - 54.3 - 79.1 = 46.6 degree$

now using above equation

$93.8^2 = 62.1^2 + b^2 - 2*62.1*b * cos46.6$

$4942.03 = b^2 - 85.34 b$

$b^2 - 85.34b - 4942.03 = 0$

by solving above quadratic equation we have

$b = 124.9 m$

so it is at distance 124.9 m from deer a

Answer:

1.) volume = 8 cm^3

2.) density = 2.6 g/cm^3

Explanation:

1.) volume =

$side {}^{3}$

=》

${2}^{3}$

=》

$8 \: cm {}^{3}$

2.) density =

$\frac{mass}{volume}$

=》

$\frac{20.8}{8}$

=》

$2.6 \: g \: cm {}^{ - 3}$

density = 2.6

A jet travels at 489 meters per second how long does it take to travel 235 m? answer in seconds

Sladkaya [172]

if in 1 second the jet goes 428 meters and you want to know how long it takes to go 237 meters you just divide 237/428

it can be written like this

_1_ = __x__

428 237

cross multiply

428 times x = 1 times 237

428x=237

divide by 428 on both sides

x= 237/428

x=0.5537 seconds

Can positive force of energy be used against negative force of energy. To create continuum of movement.

ololo11 [35]

There are no rules that can be used to answer that question.
Some of the main reasons include:

-- There's no such thing as the force of energy.
and
-- There's no such thing as negative force.
and
-- The phrase "continuum of movement" is rather vague.

Otherwise, the question is quite intriguing.
