What is a RMS?
RMS stands for Root Mean Squared. It is this average voltage that is read on a multimeter.
What is meant by rms velocity?
rms means root mean square, or in a roundabout way the average. Therefore the average velocity or average speed (of a car?)
What temperature will xenon atoms have same average speed that Cl2 molecules have at 24 degrees C?
First you need to find the root mean square speed of Cl2 at 24 degrees C using the formula sqrt(3RT/Mm) where R is the gas constant, T is the temperature in K, and Mm is molar mass. Approximately 34.24 m/s. Now perform a simple algebra problem to solve for the temperature Xenon atoms will reach this speed.
Formula for speed of an object?
If an object is at rest then falls vertically you can use the formula Vsquared=Usquared+2AD (Sorry keyboard wont let me do the 2 for square)Where V = Final Velocity (speed),U=Initial velocity (at rest =0)A= Acceleration (9.81 metres/sec or 32ft/sec in imperial)S= Distance.An object on a shelf 3m above the ground falls. Speed on impact with the floor would beSquare root V= 0 squared+2*9.81*3: = 7.672m/sSpeed = Distance/Time (Distance divided by Time)Speed=distance/timeSpeed is measured in m/s (meters per second)You can calculate speed using the following formula :Speed = Distance/TimeExamples:distance=100 meters=20s s=d/ts=100m/20ss= 5m/sthe units for speed equal up to m/s units always.so then your speed is 5 m/s
Which term describes how fast the atoms in an object are moving?
If you are thinking on the atomic scale, we usually use the root mean square speed. On the macro scale this is reflected in the temperature.
True or false. As a gas heats up the average root mean squared speed of its molecules speeds up?
true
What is the square root of 8 squared?
Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.
What is the root-mean-squared speed of the helium atom in one mole of an ideal gas at a pressure of 2.00 atmospheres and a temperature of 30 degrees C. A He atom has a mass of 4u?
What is the root-mean-squared speed of the helium atom in one mole of an ideal gas at a pressure of 2.00 atmospheres and a temperature of 30 degrees C?
What is the square root of the speed of light squared?
The speed of light [3.0 x 108ms-1]
How do you state the Pythagoras Theorem?
the formula is a squared + b squared = c squared to find the hypotenuse (the longest side) find the square root of you previous answer.
What is the distance between points 8 2 and 3 8?
Square root of 61. Distance formula is: square root of ((x1-x2)squared + (y2-y1)squared))
How do you find the length of the leg of a triangle?
if you mean a right triangle then the formula is a squared + b squared = c squared. a and b are the legs and c is the hypotunese. the legs are the smallest number then the hypotenese. An example is a=3 , b= ? and c =5 use the formula : a squared + b squared = c squared 3 squared + b squared = 5 squared 9 + b squared = 25 -9 - 9 _________________________________________ b squared = 16 Then you have to take the squared root of 16 which is 4 and 4 is b squared.
What is the formula to find the diagnal of a square?
diagonal = square root ( side squared + side squared) = square root (2) x side (pythagorean theorem since angle is 90degrees)
What formula would you use to find the distance from one point to another?
The Distance Formula! D = square root of (y2-y1) quantity squared + (x2-x1) quantity squared
What is the quadraic formula?
-b + or - the square root of b squared - 4ac over/divided by 2a
What does i squared mean in epidemiology?
i is an imaginary number which equals the square root of -1. i squared is simply -1.
Formula for surface area of a pyramid?
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
