Why do a planets speed change in orbit

Chemistry
1 answer:
gayaneshka [121]2 years ago
3 0

According to Kepler's  second law of orbital motion, a plane's orbital speed changes , depending on how far it is from the sun. The closer a planet is to the sun, the stronger the sun's gravitational pull on it, and the faster the planet moves.  The farther away from the sun, the weaker the sun's gravitational pull and the slower it moves in its orbit.

The orbit of a planet around the sun is not  a perfect circle, but  an ellipse - a flattened circle.

A 500 ml aqueous solution of na3po4 was prepared using 82g of the solute. what is the molarity​
liraira [26]

Answer:

1 M

Explanation:

The molarity of a solution, M, is a measure of the concentration of that solution and it refers to the number of moles of solute (mol) per liter (L) of solution. The molarity (M) can be calculated using the formula:

M = number of moles (n) /volume (V)

In this question, a 500 ml aqueous solution of Na3PO4 was prepared using 82g of the solute.

Molar mass of Na3PO4 = 23(3) + 15 + 16(4)

= 69 + 31 + 64

= 164g/mol

Mole = mass/molar mass

mole = 82/164

mole = 0.5 mol

Volume in Litres (L) = 500 ml ÷ 1000 = 0.500L

Therefore, Molarity (M) = 0.5/0.500

Molarity = 1 M or 1 mol/L

Why did bohrs observations of gaseous elements not reveal a complete spectrum when the light was shone through a prism? explain
Vika [28.1K]
The Bohr model proposed that electrons could just have characterized vitality levels thus when rotting back to a lower vitality level discharge a specific measure of vitality. Since the measure of vitality could be changed over to a specific recurrence then particular emanation lines were found in the electromagnetic range. Alternate speculations couldn't clarify the discharge lines.
