Question

22/77 और 22/154 का अन्तर ज्ञात करो।​

Answer 1

$\huge\mathbb{SOLUTION:-}$

$\sf\underline{\purple{\:\:\:Given:-\:\:\:}}$

$\sf\implies \dfrac{22}{77}\:\:and\:\:\dfrac{22}{154}$

We have to find difference between them

Now :-

$\sf\underline{\red{\:\:\:A.T.Q:-\:\:\:}}$

$\sf\implies \dfrac{22}{77}-\dfrac{22}{154}\\ \\ \sf\:\:\:\:take\:L.C.M\:\:of\:77\:and\:154\\ \\ \sf\:\:\:L.C.M\:of\:77\:and\:154= 154\\ \\ \sf\implies \dfrac{22\times 2-22}{154}\\ \\ \sf\implies \dfrac{44-22}{154}\\ \\ \sf\implies \dfrac{22}{154}$

$\sf{\underline{\:The\: Difference\: between\:}}\:\dfrac{22}{77}\:and\:\dfrac{22}{154}\\ \\ \sf\implies \dfrac{22}{154}$

Answer 2

Step-by-step explanation:

Mass = 500 kg

Velocity = 0.2 m/s

To find:

Power of machine in HP

Calculation:

power = force \: \times velocitypower=force×velocity

\begin{lgathered}= > P = F \times v \\ = > P = (m \times g) \times v \\ = > P = (500 \times 10) \times 0.2\end{lgathered}

=>P=F×v

=>P=(m×g)×v

=>P=(500×10)×0.2

= > P = 1000 \: watts=>P=1000watts

Now as per the question,

[ 1 HP = 746 watts ]

\begin{lgathered}\therefore 1000 \: watts \\ = \dfrac{1000}{745} \\ = 1.3404 \: HP\end{lgathered}

∴1000watts

=

745

1000

=1.3404HP

So, final answer :

\boxed{\red{Power \: = \: 1.3404 \:HP}}

Power=1.3404HP

Additional information on Power :

1. It's a scalar quantity

2. It only has magnitude and no direction

3. It is defined as the rate of change of work .

4. It can also be expressed as the product of force and velocity
