Explanation:

this is the answer

now u can understand

• Mass of Hammer = 1 kg
• Mass of Iron Nail = 0.2 kg (200g)
• Velocity of Hammer = 50m/s

Rise (or change) in the temperature if the Hammer uses half of its energy in heating the nail

First, Let's Find out the initial energy of the Hammer:

[tex] \implies \displaystyle \rm ke = \frac{1}{2} m {v}^{2} [/tex]

[tex] \implies \displaystyle \rm ke = \frac{1}{2} {50}^{2} [/tex]

[tex] \implies \displaystyle \rm ke = \frac{1}{2} {2500}[/tex]

[tex] \implies \displaystyle \rm ke = {1250}j[/tex]

So, The initial Energy of Hammer = 1250 J

As Given, Half of the energy is used in Heating up the Iron nail,

So, Q = Initial Energy/2

or, Q = 1250/2

or, Q = 625

So, The heat energy produced is 625J

Now, using the Formula :

[tex] \implies \displaystyle \rm q = mc \triangle t[/tex]

[tex] \implies \displaystyle \rm 625= 0.2 \times 419 \times \triangle t[/tex]

[tex] \implies \displaystyle \rm 3125= 419 \times \triangle t[/tex]

[tex] \implies \displaystyle \rm\triangle t = \frac{3125}{419} [/tex]

[tex] \implies \displaystyle \rm\triangle t = 7.4[/tex]

So, the Change in Temperature = 7.4°C

The answer to the given question is written below.

• Madhav collected information about monthly expenditure of a family.
• He carefully wrote them in blank sheets.
• This type of data collection is known as Primary Data.
• The primary data refers to the first hand written credentials which are written by the researcher.
• In this case, the monthly expenditure of the family is primary data.
• Later, this will be entered into Excel sheets, which would be registered as official records.
• This data will be known as Secondary Data.

Correct Question: Madhav collected information about monthly expenditure of a family. What type of data is this?

Answer:

Concept : Micro Economics

Explanation:

Micro Economics studies the individual economics unit

such as individual consumer, individual producers, individual firms the price of a particular commodity

or a factor

Hence this illustration related to the concept of 'MicroEconomics'

where Madhav Collected the Information about the income of a family

Answer:

10375/1000 i pray that this answer will help you

Answer:

Write 10.375 in --

[tex] \frac{10.375}{1} \\ [/tex]

Now, multiply both numerator and denominator by 10 for every number after the decimal point..

[tex] \frac{10.375 \times 1000}{1 \times 1000} = \frac{10375}{1000} \\ [/tex]

Finally reduce the fraction by cutting both of then with 125 -->

[tex] \frac{10375}{1000} = \frac{83}{8} \\ [/tex]

Therefore, 83 / 8 is the required fraction in simplest form...

Hope it helped you..

Thank you !!!

Explanation:

स कविता के माध्यम से कवि ने पर्वतीय प्रदेश के सायंकालीन प्राकृतिक सौंदर्य को दर्शाने का प्रयास किया है। शाम को किसान के रूप में बताया है। पहाड़ किसान के रूप में घुटने मोड़े बैठा है। उसके सिर पर आकाश का साफ़ा बँधा है और घुटनों पर नदी की चादर पड़ी है। सूरज चिलम यॊ रहा है। साथ ही में पलाश के जंगल की अँगीठी दहक रही है और दूर पूरब में अंधकार भेड़ों के झुंड के रूप में धीरे-धीरे बढ़ता जा रहा है। उसी समय, मोर की आवाज आती है जैसे कह रहा हो-सुनते हो। उसकी आवाज़ से लगता है शाम रूपी किसान हड़-बड़ा कर उठ गया जिससे चिलम उलट गई और चारों तरफ़ धुआँ फैल गया यानी अँधेरा छा गया। सूरज के डूबने से शाम बीत गई और रात हो गई ।
