Answer:

f = 3 × 10⁶ Hz

Explanation:

Given data:

Wavelength of wave = 1.0 ×10² m

Frequency = ?

Solution:

Formula:

Speed of light = wavelength× frequency

Frequency = speed of light / wavelength

speed of light = 3× 10⁸ m/s

f = 3× 10⁸ m/s / 1.0 ×10² m

f = 3 × 10⁶ s⁻¹

s⁻¹ = Hz

f = 3 × 10⁶ Hz

Answer:

0.99 pounds

2,000 oz

0.423 cups

Explanation:

In order to convert this units we need to look up their equivalences.

1 g equals 0,0022 pounds approximately

Then we need to cross-multiply:

$\frac{1 g}{0.0022 pounds} = \frac{450 g}{ Xpounds} \\x = \frac{450 g x 0.0022 pounds}{1 g}$

450 g equals 0.99 pounds approximately

We can do the same calculation for the other 2 ingredients

1 g equals 16 oz

Then (125 g x 16 oz) / 1 oz = 2,000 oz (or 500 4 oz)

1 cup equals 236.59 ml

Then (100 ml x 1 cup)/ 236.59 = 0.423 cups

The answer to the question?

Artemon [7]

Answer:

atomic particles

The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

A gas container has a volume of 446.9 with a temp of 14c. When the volume is decreased to 238.7l the new temp is what

swat32

Answer:

$\frac{V _{1}}{T _{1}} = \frac{V _{2}}{T _{2} } \\ \frac{446.9}{(14 + 273)} = \frac{238.7}{T _{2} } \\ {T _{2}} = \frac{238.7 \times 287}{446.9} \\ {T _{2}} = 153.3 \: kelvin \\ = 119.7 \degree \: c$

A concentrated salt solution has a mass of 5.34 g for a 5.00 ml sample. what is the specific gravity of this solution?

Nutka1998 [239]

The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.

Density of a substance is

Density = Mass / Volume

= 5.34/5

= 1.07

Density of water = 1

Specific gravity = Density of substance/density of solvent

Specific gravity = 1.07 / 1

Specific gravity = 1.07

Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.

If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.

Isotopes are created by adding or removing neutrons from the nucleus.

valina [46]

Answer:

<h2>This is TRUE statement... </h2>

Explanation: 

When you remove or add a neutron to the nucleus of an atom, the resulting substance is a new type of the same element and is called an isotope.
