We have that for the Question,it can be said that the field has a <u>value </u>of
From the question we are told
a small object with a charge of magnitude q creates an electric field. at a point 1.0 m to the north of the charge the field has a value of 2.0 n/c directed south. at a <em>point </em>0.5 m to the west of the <em>charge </em>the field has a value of
<h3> Electric
field </h3>
Generally the equation for the <em>electric</em> field is mathematically given as
Therefore

I think these forms are called isotopes of each other.
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

<span>Alicia
wanted to pull out a particular issue from a pile of magazines. First,
she tried pulling slowly, and the whole pile began to move. Then she
tried pulling quickly, and the issue she wanted came out without the
pile moving. The pile did not move because of the?
a. larger force Alicia applied
b. smooth surface of the magazines
c. inertia of the pile and friction <--- *** Answer ***
d. friction between the magazines
(If this is your question)
Hope this helps :p

Answer:
(a)
(b) 43.45 m
(c) 12.58 m
Explanation:
By applying newton's law on car,
where is the friction force and m is mass, a is acceleration
a = acceleration of car
(b)
From kinematic equation
but u=0 hence
and making s the subject
(c
From the kinematic equation
