WHAT DOES DENSITY HAVE TO DO WITH PLATE TECTONICS?<br> Explain

Korvikt [17]

Answer: The reason for the differences in density is the composition of rock in the plates. When two plates come in contact with each other through plate tectonics, scientists can use the density of the plates to predict what will happen. Whichever plate is more dense will sink, and the less dense plate will float over it.

Which statement best define percent error? check all that apply.

Art [367]

Percent error is the difference between the experimental value and theoretical value and measures the accuracy of the result found. The larger the error, lesser is the accuracy and vice versa.

Solution:

It is a mathematical way of showing accuracy

The higher the percent error, the less accurate the data set,

a car travels between the 100 meter and the 250 meter highway marker in 10 seconds calculate the velocity of the car during this

kozerog [31]

$Given:\\\Delta s= 250m-100m=150m\\t=10s\\\\Find:\\v=?\\\\Roz.\\\\v=\frac{\Delta s}{t} \\\\v=\frac{150m}{10s} =15\frac{m}{s}$

How is the combined gas law used to calculate changes in pressure, temperatures, and/or volume for a fixed amount of gas?

nalin [4]

Answer:

Let's start by considering the ideal gas law:

$pV=nRT$

where

p is the gas pressure

V is its volume

n is the number of moles

R is the gas constant

T is the absolute temperature

This equation can also be rewritten as

$\frac{pV}{T}=nR$

Now, if we consider a fixed amount of gas, this means that the number of moles (n) is constant. So we can rewrite the equation as

$\frac{pV}{T}=const.$

And therefore, if we consider a gas undergoing a certain transformation from 1 to 2, we can write

$\frac{p_1V_1}{T_1}=\frac{p_2V_2}{T_2}$

where 1 indicates the conditions of the gas at the beginning and 2 the conditions of the gas after the process. So, the change in pressure/temperature/volume of the gas can be found by using this equation.
