If the velocity of a wave is 12 m/s and its frequency is 600 hertz, what would be its wavelength?
Black_prince [1.1K]

Answer:

<em>»</em><em> </em><em>λ </em><em>=</em><em> </em><em>0</em><em>.</em><em>0</em><em>2</em><em>m</em>

Explanation:

Given :

Velocity of the wave {v}= 12 m/s

Frequency {f} = 600 Hz

Apply Wavelength formula :

• λ =  \frac{v}{f}

→ λ = \frac{12}{600}

→ λ = \frac{1}{50}

→ λ = 0.02m

A piece of copper has a mass of 660 g. How many atoms does the sample contain?
son4ous [18]
The conversions that will be used are:

1 mole of copper / 63.5 grams of copper
6.02 x 10²³ atoms of copper / 1 mole of copper

Multiplying the given mass by these conversions,

660 g * (1 mol Cu / 63.5 g Cu) * (6.02 x 10²³ Cu atoms / 1 mole Cu)

The sample contains 6.25 x 10²⁴ atoms of copper
