A rock's composition is not changed by mechanical weathering. Only the size of the fragments decreases. ... Mechanical weathering breaks rocks down into smaller fragments, and increases the surface area of the over all material. By increasing the surface area, chemical processes may act more easily upon the rock surface.
Answer:
v = 1130 cm³
Explanation:
Given data:
Volume of sample = ?
Mass of Al sample = 3.057 Kg (3.057 Kg× 1000g/1 Kg = 3057g)
Density of Al sample = 2.70 g/cm³
Solution:
Formula:
d = m/v
d = density
m = mass
v= volume
by putting values
2.70 g/cm³ = 3057g /v
v = 3057g /2.70 g/cm³
v = 1130 cm³
So for the first bit Swinging a ball around is like the moon going around the earth because instead of the earth and moon its you and the ball. For the second part of it the inward force is the earths gravity is pulling on it and since it has a greater mass the force is greater at closer distances. By the way the moon wants to move in a straight line. I hope that helps you out.
Answer:
I don't know what you're saying cuz give me the brainless answer please
<h3>
Answer:</h3>
Partial pressure of He(P(He) = 1.5 atm.
Partial pressure of Ne(P(Ne) = 1 atm.
Partial pressure of Ar(P(Ar) = 0.5 atm.
<h3>
Explanation:</h3>
According to Dalton law of partial pressure the sum of partial pressures of individual gases in a gaseous mixture is equivalent to the total pressure.
The partial pressure of a gas in a gaseous mixture is given by the product of the mole fraction and the total pressure.
Our gaseous mixture contains He, Ne, and Ar and the total pressure is 3 atm.
Since we are given the ratios of the gases in the mixture, we can calculate the partial pressure of each gas.
P(He) = 3/6 × 3 atm.
= 1.5 atm.
P(Ne) = 2/6 × 3 atm.
= 1 atm
P(Ar) = 1/6 × 3 atm.
= 0.5 atm
Therefore, the partial pressures of gases He, Ne and Ar are 1.5 atm, 1 atm, and 0.5 atm respectively.
