Answer:

Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.

Answer: <u><em>Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. This unique tilt causes the most extreme seasons in the solar system. </em></u>

<u><em>Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings. </em></u>

<u><em>The inner rings are narrow and dark.Like the other gas giants, Uranus has an atmosphere composed of mostly hydrogen, followed by helium and a little methane. What is very interesting about Uranus is that the planet has an enormous 98 degree tilt on its axis.</em></u>

A 3.20 g sample of a salt dissolves in 9.10 g of water to give a saturated solution at 25°C. a. What is the solubility (in g sal

muminat

Answer:

The solubility of the salt is 35.16 (g/100 g of water).

It would take 71.09 grams of water to dissolve 25 grams of salt.

The percentage of salt that dissolves is 52.7 %

Explanation:

We know that 3.20 grams of salt in 9.10 grams of water gives us a saturated solution at 25°C. To find how many grams of salt will gives us a saturated solution in 100 grams of water at the same temperature, we can use the rule of three.

$\frac{3.20 \g \ salt}{9.10 \ g \ water} = \frac{x \ g \ salt}{100 \ g \ water}$
