The correct answer is A; or 9.38x10^-3.

Explanation:

f=3.20x10^10       c= 3.00x10^8

Once you divide those by each other, your answer is 9.83x10^-3

Hope this helps!! :)

The wavelength of the radio waves is 9.38 \times 10^{{3} m

<u>Explanation</u><u>:</u>

Given:

Frequency= 3.20 x 1010 Hz

Wave speed or speed of light= 3.00\times10^8

To Find:

Wavelength of radio waves= ?

Solution:  

Wavelength of radio waves  is mathematically expressed as

\lambda= \frac{c}{f}

where

f = frequency

c= wave speed or speed of light

\lambda = wavelength of radio.

So,

\lambda=\frac{c}{f}

\lambda= \frac{3.00\times10^8}{ 3.20 \times10^{10}}

\lambda=0. 938\times 10^ {{-2}

\lambda= 9.38\times 10^ {{-3}

10) an object has mass of 50g 500mg and 0.1g. express the total mass of the object in grams
Pavel [41]
500 mg in g :

1 g ----------- 1000 mg
? -------------- 500 mg

500 x 1 / 1000 => 0.5 g

total mass:

50 g + 0.5 g + 0.1 g => 50.6 g
