Answer:
The number is 95.
Step-by-step explanation:
Solution,
Let the number be 'x'.
So, of 'x' =
Now according to question, is equal to 38.
So we can frame it as;
Now we solve it;
For solving it we will multiply both side by '5' using multiplication property and get;
Now using division property, we will divide both side by '2' and get;
Hence The number is 95.
A simple way to get the dimensions is just to rearrange the equation.
<span>So in a.) (i'm going to assume t2 is t squared) </span>
<span>rearrange: </span>
<span>x = Bt2 ----> B= x/t2 </span>
<span>Now you are told that x is displacement (L) and t is time (T) so sub these in. </span>
<span>B= L/T2 Therefore the dimensions are L/T2. </span>
<span>In b.) following the same steps: </span>
<span>x = A sin(2πft) ----> A = x/sin(2πft) </span>
<span>The hint tells you that sin(2πft) is dimensionless so you can disregard that part. </span>
<span>A = x </span>
<span>A=L</span>
