Answer:
Magnitude of the resultant force will be 20N in the direction of .
Explanation:
It's given in the question that two forces have been applied on the object given.
Since force is a vector quantity, therefore, it has magnitude and direction both.
Both the forces are in the opposite directions.
Therefore, magnitude of the resultant force of these forces will be,
= 20 N
And the direction of the resultant force will be towards .
Therefore, magnitude of the resultant force will be 20N in the direction of .
A sample of an ideal gas is heated, and its kelvin temperature doubles. The average speed of the molecules in the sample will increases by a factor of
The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path.
Root mean square speed is a statistical measurement of speed.
The root mean square speed can be calculated as : V1 :
if temperature becomes double
let T1 is initial temperature
So , T2 = 2 * T1
now ,
Root mean square speed will be (V2) =
= *
= V1
Thus when temperature becomes double, the root mean square speed increases by a factor of
