Answer 1

Answer:

Jeremy accidently dropped his toy stuffed animal from the balcony of his apartment on the fourth floor. The toy hit the ground at a velocity of 16.0 meters/second. At impact, it took 2.0 seconds for the toy’s velocity to reach 0 meters/second. If the toy has a mass of 0.25 kilograms, what's the force of the impact? Use F = ma, where .

The force of the impact is how many newtons.

Q1.Convert the octal number 132 into binary number.

$\large{\bold{\underline{Solution - \: }}}$

For finding octal number 132 into binary number first look at the table given below

$\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\begin{array}{cccc}\sf Octal &\sf binary \\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{}\\\sf 0&\sf \ 000 \\\\\sf 1 &\sf \ 001\\\\\sf 2&\sf \ 010 \\\\\sf 3&\sf 011\\\\\sf 4&\sf 100 \\\\\sf 5&\sf101 \\\\\sf 6&\sf 110 \\ \\\sf 7&\sf 111 \\\\\sf 8&\sf 1000 \\\\\sf 9&\sf 1001 \\\\\\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{\bf{}}\end{array}}\end{gathered}\end{gathered}\end{gathered}\end{gathered}\end{gathered}\end{gathered}$

Now , Use the table below to make these conversions

$\rightarrow \sf(1)_8 = (001)_2$

$\rightarrow \sf(3)_8 = (011)_2$

$\rightarrow \sf(2)_8 = (010)_2$

now group each value to make a binary number

001 011 010 = 1011010

$\begin{gathered}\begin{gathered}\begin{gathered}\\\;\underline{\boxed{\tt{\odot\;hence\;Answer\;=\;\bf{\blue{A) 1011010}}}}}\end{gathered} \end{gathered}\end{gathered}$

Q2.Convert the binary number 111111 into octal number.

$\large{\bold{\underline{Solution - \: }}}$

For finding binary number 111111 into octal number first look at the table given below

$\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\begin{array}{cccc}\sf binary&\sf Octal\\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{}\\\sf 000&\sf \ 0 \\\\\sf 001 &\sf \ 1\\\\\sf 010&\sf \ 2\\\\\sf 011&\sf 3\\\\\sf 100&\sf 4 \\\\\sf 101&\sf5 \\\\\sf 110&\sf 6 \\ \\\sf 111&\sf 7 \\\\\sf 1000&\sf 8 \\\\\sf 1001&\sf 9 \\\\\\\frac{\qquad \qquad \qquad \qquad}{}&\frac{\qquad \qquad \qquad \qquad}{\bf{}}\end{array}}\end{gathered}\end{gathered}\end{gathered}\end{gathered}\end{gathered}\end{gathered}$

Now , you can Use the table to convert each set of three into an octal digit.

$\rightarrow \sf(111)_2 = (7)_8$

$\rightarrow \sf(111)_2 = (7)_8$

→ 77

$\begin{gathered}\begin{gathered}\begin{gathered}\\\;\underline{\boxed{\tt{\odot\;hence\;Answer\;=\;\bf{\blue{D) 77}}}}}\end{gathered} \end{gathered}\end{gathered}$
