Explanation:
it could be possible if the car has all the right aro dynamics
<em>Class I .</em> . .
The fulcrum is between the effort and the load.
The mechanical advantage may be any positive number, more or less than ' 1 '.
<em>Class II .</em> . .
The load is between the fulcrum and the effort.
The mechanical advantage is always greater than ' 1 '.
<em>Class III .</em> . .
The effort is between the fulcrum and the load.
The mechanical advantage is always less than ' 1 '.
Answer:
Explanation:
From the question we are told that:
Average distance 
Generally the equation for change in electric potential energy is mathematically given by
Where
U_1=0 Because of initial lengthy distance apart
And
Therefore
These choices are not "levels" of sound. They're frequencies of sound.
The lower limit of audible frequency is usually considered to be 20 Hz.
But there are some people with ears that can hear 10 Hz, and others ...
particularly the elderly ... who can't hear anything below 100 Hz.
The question is a rather poor one.
