Which element has 32 protons in its nucleus? phosphorus cobalt germanium sulfur
vovangra [49]

Answer:

Germanium.

Explanation:

In a neutral atom: the number of protons = the number of electrons.

Atomic number of a neutral atom = number of electrons = number of protons.

  • Phosphorous is an element with atomic number 15 and thus contains 15 electrons and 15 protons.

  • Cobalt is an element with atomic number 27 and thus contains 27 electrons and 27 protons.

  • <em>Germanium is an element with atomic number 32 and thus contains 32 electrons and 32 protons.</em>

<em></em>

  • Sulfur is an element with atomic number 16 and thus contains 16 electrons and 16 protons.

#5.) Explain why the rock cycle is referred to as a "cycle".
Natalka [10]
The rock cycle is referred to as cycle because it repeats over and over again. The definition of cycle is a series of events that are regularly related in the same order. So with the rock cycle they stay in the same order and repeat.
Hope this helps :)

The green light emitted by a stoplight has a wavelength of 525 nm. What is the frequency of this photon? (c = 3.00 × 10⁸ m/s).
Reil [10]

The frequency of this photon is 5.94 x 10^{14} H_{Z}.

Solution:

The speed of light has a value of approximately <u>3.00×108 m/s</u>

The wavelength should have units of meters.

The frequency should have units of Hz or s−1. Hz is hertz or reciprocal seconds.

We know the value of the speed of light and we are given the wavelength. All we have to do is rearrange the equation to solve for the frequency:

<u>v = c/λ</u>

= 3.00×10^{8} m/s/505×10^{-9} m

= 5.94X10^{14}s-1

= <u>5.94X</u>10^{14}<u> Hz</u>

<u />

Frequency describes the number of waves passing through a particular location at a particular time. A class interval frequency is the number of observations that occur in a particular predefined interval. So, for example, if 20 of her ages 5-9 appear in the survey's data, the interval 5-9 has a frequency of 20. The class interval endpoints are the lowest and highest possible values ​​of the variable.
