You have to use the equation v=λf
v is the velocity of the wave
λ is the wave length of the wave (how far the wave goes in one cycle)
f is the frequency of the wave (how long one cycle is) 

V=4m×3Hz
v=12m/s

Hz stands for s⁻¹ which is why the final units is m/s

I hope this helps.  Let me know if anything is unclear.

Atoms whose atomic number are the same but whose mass numbers are different are called: alpha particles ions beta particles isot
Kaylis [27]
<h2>Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes </h2>

Explanation:

Isotopes

They are the   elements with same atomic number but different mass number .

for example : Protium , deuterium and tritium are isotopes of hydrogen .

                    : C-14 and C-12 are isotopes of oxygen .

                     : Cl-35.5 and Cl-37 are isotopes of chlorine

Alpha particles

They are helium nuclei with +2 unit charge and 4 a.m.u mass

They are represented as : He₂⁴.

Ions

The atom carrying charge is called as ion .

It can be of two types : Cation and anion

cation :atom with positive charge

Anion : atom with negative charge

Beta particles

They are actually particles with charge and mass of electron and is represented as :₀ e⁻¹

Which of these time measurements is the smallest?
Anuta_ua [19.1K]

Answer:

In order to answer the question, we convert the measurements given to a common base unit. For this case, we use seconds.

A)   0.02 seconds

B)   0.02 teraseconds x (10^12 s / 1 terasecond) = 2x10^10 seconds

C)   2,500 milliseconds x (1 s / 1000 ms) = 2.5 seconds

D)   25,000 nanoseconds x (1 x 10^-9 s / 1 nanosecond) = 2.5 x 10^-5 seconds

So ,The correct answer is option " D "

35mL of acid with an unknown concentration is titrated to completion using 63mL of 3.0 MNaOH.
siniylev [52]

Answer:

5.4 M.

Explanation:

  • At complete neutralization: It is known that the no. of millimoles of acid equal that of the base.

<em>(MV)acid = (MV)NaOH</em>

M of acid = ??? M, V of acid = 35.0 mL.

M of NaOH = 3.0 M, V of NaOH = 63.0 mL.

∴ M of acid = (MV)NaOH / (V)acid = (3.0 M)(63.0 mL)/(35.0 mL) = 5.4 M.

How is the water cycle realated to weather patterns and climate? Make sure to put 2 evidences
Setler79 [48]
When there’s water in a department such as a lake, pound or/and ocean, the water tends to evaporated into the air and that’s how/when clouds are created. The same water from those locations are the same water that comes from the rain water, it’s a cycle that creates and takes water
