Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the s
a_sh-v [17]

Explanation:

The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m

We need to find which wave have a higher frequency.

The relation between frequency and wavelength is given by :

c=f\lambda

Let f₁ and f₂ be the frequency of wave 1 and wave 2.

f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz

And

f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz

Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.

What orbital type is being filled throughout the transition metal B Groups?
Nataliya [291]

Answer:

The correct answer is: d-orbital

Explanation:

The transition metals are the chemical elements that belong to the B-group of the periodic table, from group 1B to 8B. The B-group is located between the groups IIA and IIIA in the periodic table.

The general electronic configuration of the chemical elements belonging to this group is (n-1) d¹⁻¹⁰ ns⁰⁻², because of the <u>partially filled d-subshell</u> in the ground state or excited state. <u>Therefore, the transition metals are refereed as the </u><u>d-block elements</u><u>.</u>

Dimensional analysis: if you count at the rate of 2 numbers every secound, how many days whould it take you to count to 1 millio
son4ous [18]

Answer:  5 days

Explanation:

1,000,000/2 = 500,000 *do this because of the 2 numbers every second

500,000/60= 8,333.33 *do this to get minutes

8,333.33/60= 138.88 *do this to get hours

138.88/24= 5.7866 *do this to get days

5 days 7 hours 8 minutes 6 seconds
