Answer:
⇝ Given :-
A bus starting from rest moves with a uniform acceleration of 0.1 m/s² for 2minutes.
⇝ To Find :-
The speed accqired and Distance traveled.
⇝ Solution :-
❒ Converting Time in Seconds :-
We Have,
\begin{gathered} \text{Time= 2 mins} \\ \end{gathered}
Time= 2 mins
\begin{gathered} = \rm( 2 \times 60)second \\ \end{gathered}
=(2×60)second
\red{:\longmapsto \text{Time = 120 \:s}}:⟼Time = 120 s
Here,
Initial Velocity = u = 0 m/s
Time Taken = t = 120 s
Acceleration = a = 0.1 m/s²
1 》 Calculating Speed Acquired :-)
Let Speed Acquired by Car be = v m/s
❒ We Have 1st Equation of Motion as :
\begin{gathered}\large \bf \red \bigstar \: \: \orange{ \underbrace{ \underline{v = u + at}}} \\ \end{gathered}
★
v=u+at
⏩ Applying 1st Equation of Motion ;
\begin{gathered}:\longmapsto \rm v = 0 + 0.1 \times 120 \\ \end{gathered}
:⟼v=0+0.1×120
\begin{gathered}:\longmapsto \rm v = 0.1 \times 120 \\ \end{gathered}
:⟼v=0.1×120
\purple{ \Large :\longmapsto \underline {\boxed{{\bf v = 12} }}}:⟼
v=12
Therefore,
\large\underline{\pink{\underline{\frak{\pmb{\text Speed \: \text Acquired = 12m/s }}}}}
SpeedAcquired=12m/s
SpeedAcquired=12m/s
2 》Calculating Distance Traveled :-)
❒ We Have 2nd Equation of Motion as :
\begin{gathered}\large \bf \red \bigstar \: \: \orange{ \underbrace{ \underline{s=ut+\dfrac{1}{2}at^2}}} \\ \end{gathered}
★
s=ut+

⏩ Applying 2nd Equation of Motion :
\begin{gathered}:\longmapsto \rm s = 0 \times 120 + \frac{1}{2} \times 0.1 \times 102 {}^{2} \\ \end{gathered}
:⟼s=0×120+

×0.1×102

\begin{gathered}:\longmapsto \rm s = 0 + \frac{1}{2} \times 0.1 \times 14400 \\ \end{gathered}
:⟼s=0+

1
×0.1×14400
\purple{ \large :\longmapsto \underline {\boxed{{\bf s = 720 \: m} }}}:⟼
s=720m
Therefore,
\large\underline{\pink{\underline{\frak{\pmb{ Distance \text Traveled = 720 \: m }}}}}
Distance Traveled
Answer:
रागनर नवर्से के अनुसार- यह दुश्चक्र अनेक शक्तियों का ऐसा चक्रीय समूह है जो एक-दूसरे को प्रभावित करता है । एक गरीब देश में आय कम होती है । अत: बचत भी कम हो पाती है, न्यून बचत के कारण न्यून विनियोग होता है ।
