The atomic number is always equal to the total number of which is also equal to the total number of
denis23 [38]

Answer:

Protons; electrons.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.

Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons. All the physical properties of a mineral result from the mineral's internal arrangement of atoms.

The atomic number is always equal to the total number of protons, which is also equal to the total number of electrons. Protons are the positively charged particles that make up an atom while electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

A chemical element is denoted by X_{Z}^{A}

Where;

X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Therefore, the number of neutrons = A - Z

A wave hits The Beach every 10 seconds whats its frequency?
natta225 [31]

Answer:

<em>The frequency of the wave is 0.10 Hz </em>

Explanation:

Number of vibrations or number of waves per unit time is called frequency. The SI unit of frequency is Hz. It is given by the equation  

In this question time = 10 seconds

number of waves = 1

frequency= \frac {number of waves} {time interval} = \frac {1}{10} = 0.10 Hz

Frequency is a characteristic feature of waves. Other characteristics of a wave are time period, amplitude etc. Time period is the time taken for one complete vibration and frequency is obtained by taking the reciprocal of time period.

frequency F=1/T

A rocket accelerates at a rate of 16.4m/s^2 for a distance of 50m. What is the speed at the
NARA [144]

Answer:

40.5 m/s

Explanation:

Given:

v₀ = 0 m/s

a = 16.4 m/s²

Δx = 50 m

Find: v

v² = v₀² + 2aΔx

v² = (0 m/s)² + 2 (16.4 m/s²) (50 m)

v = 40.5 m/s
