In a classical model of the singly-ionized helium atom, a single electron orbits the nucleus in a circular orbit of radius.

NikAS [45]

Yes, in a classical model of the singly-ionized helium atom, a single electron orbits the nucleus.

<h3>What is singly ionized helium?</h3>

Singly ionized helium is an atom that has lost one electrons from its outermost shell. We consider its remaining electron like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom which is the number of protons in the nucleus so the nucleus charge on singly ionized helium is -1.

A seashell is suspended in the air at rest by two strands of spider silk. Each strand of silk makes an angle of 75 degrees above

Ksenya-84 [330]

The mass of the seashell suspended by the two strands of spider silk is 0.28 kg.

The given parameters:

<em>Tension on each strand of silk, T = 1.42 N</em>
<em>Angle of inclination of each strand, θ = 75⁰</em>

The mass of the seashell at equilibrium is calculated by applying Newton's second law of motion;

$\Sigma F = 0\\\\T_1 sin(\theta) + T_2 sin(\theta) - W = 0$

where;

W is the weight of the seashell

The weight of the seashell is calculated as;

$1.42 \times sin(75) \ + \ 1.42 \times sin(75) \ - W = 0\\\\2.743 - W = 0\\\\W = 2.743 \ N$

The mass of the seashell is calculated as follows;

$W = mg\\\\m = \frac{W}{g} \\\\m = \frac{2.743}{9.8} \\\\m = 0.28 \ kg$

Thus, the mass of the seashell suspended by the two strands of spider silk is 0.28 kg.

_______ occurs as the energy of a photon increases?

kari74 [83]

Answer:

An increase in frequency

Explanation:

A photon is an electromagnetic radiation without mass,as the energy of a photon is increased it frequency also increases.

Consider the equation below.

Energy = hf

We're h= is the Planck constant.

F is the frequency measured in Hertz from this a direct relationship exist between the energy and frequency

Answer:

Approximately 22.9 seconds.

Explanation:

A sound wave travel 340m in 1 sec

For 7800m it will travel;

$\frac{7800}{340} * 1$ = 22.94117647 sec

It will take approximately 22.9 seconds.
