What is the relationship between the type of energy sublevels present and the

1 answer:

6 0

Each principal energy level has one sublevel containing one orbital, an s orbital, that can contain a maximum of two electrons. Electrons in this orbital are called s electrons and have the lowest energy of any electrons in that principal energy level.

Answer:

Fringe width = 21 mm

Explanation:

Fringe width is given by the formula

$\beta = \frac{\Lambda L}{d}$

here we know that

$\Lambda = 564 nm$

L = 4.0 m

d = 0.108 mm

now from above formula we will have

$\beta = \frac{(564 \times 10^{-9})(4.0 m)}{0.108\times 10^{-3}}$

$\beta = 0.021 meter$

so fringe width on the wall will be 21 mm

A horse walks along a straight path. it travels 3 in one second, 4 m in the next second, and 5 m in the third second. describe t

Temka [501]

Answer: The horse is moving with a uniform acceleration

Explanation:

According to the described situation, we are dealing with a <u>constant acceleration</u> (also called <u>uniform acceleration</u>), since the horse's velocity is changingn by a constant rate.

Let's prove it:

Firstly we are told the horse follows a straight path. In addition we are given its velocity:

3 m/s, then 4 m/s and 5 m/s

Since acceleration $a$ is defined as the change of velocity in time we can calculate it:

$a\frac{4 m/s-3 m/s}{1 s}=1m/s^{2}$ This is the horse's constant acceleration

In the opposite figure, the work done by the force F to push the box upwards from the ground to the top of the inclined plane is

goldfiish [28.3K]

In the opposite figure, the work done by the force F to push the box upwards from the ground to the top of the inclined plane is 600 J.Option c is correct.

Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.

The displacement value from the triangle is;

$\rm sin 30^0 = \frac{P}{H} \\\\ H=S =\frac{3 \ m}{sin 30^0} \\\\ S = 6\ m$

The work done is found as ;

$\rm W= Fd \\\\ W = 100 \ N \times 6 \\\\ W= 600 \ J$

The force F in the opposing figure does 600 J of effort to lift the box from the ground to the top of the inclined plane.

Hence option c is correct.
