The power of person is 333.3 watt

Explanation:

The mass of man = 50 kg

The load on his head = 60 kg

The total mass = 50 + 60 = 110 kg

The height covered by this mass h = 20 m

The work DONE W = mass x acceleration due to gravity x height

THUS W = 110 x 10 x 20 = 22 x 10³ J

The power = Work/time

Thus power = watt = W = 333.3 watt

Answer:

Java program to find whether the given number is a lead number or not

A number is said to be a Lead number is the SUM of the even digits in the number is equal to the sum of the odd digits in the number.

Program:

IMPORT java.util.*;

PUBLIC class Main

{

public static void main(String[] args) {

 Scanner sc = new Scanner(System.in);

 int number=sc.nextInt();

 int gnumber=number;

 int evensum=0;

 int oddsum=0;

 while(number!=0)

 {

    int x = number%10;

    number = number/10;

    if(x%2==0)

    {

        evensum+=x;

    }

    else{

        oddsum+=x;

    }

 }

 if(evensum==oddsum)

 {

     System.out.println(gnumber+" is a Lead number");

 }

 else{

     System.out.println(gnumber+" is NOT a Lead number");

 }

}

}

Input 1:

6374

Output 1:

6374 is a Lead number

(Explanation:

Odd digits sum = 7+3 = 10 and

Even digits sum = 6+4 = 10.

Therefore, Odd sum=Even sum)

Input 2:

6372

Output 2:

6372 is NOT a Lead number

(Explanation:

Odd digits sum = 7+3 = 10 and

Even digits sum = 6+2 = 8.

Therefore, Odd sum ≠ Even sum)

Answer:

In case of gases, when balloon is partially inflated in a cool room it EXPANDS to full size when PUT in warm water. This all is due to thermal expansion. So, increase in dimension of a BODY due to increase in temperature is thermal expansion. The expansion in LENGTH is CALLED linear expansion.

Answer:

Experts have had a TOUGH time of it of late. From politician to pollster, those in power stand accused of misunderstanding what people want. Or not caring. Or worse. Confidence in institutions and their intentions is at rock bottom.

We often see in community engagement work we do that councils’, architects’ or developers’ motivations are assumed – unfairly – to verge on the ACTIVELY malign. Society is changing. People no long believe that the MAN (it usually was a man) in Whitehall or TOWN Hall knows best. They EXPECT to influence what happens near where they live and work. And, our research shows, they are more inclined to support development when they are genuinely involved – not just in a tawdry and ersatz PR exercise.

Answer:

We can say that the divergence operation turns a vector FIELD into a SCALAR field. Note that the RESULT of the CURL is a vector field. We can say that the curl operation turns a vector field into ANOTHER vector field.

Answer:

30 watts

Explanation:

Acc. to the RELATIONSHIP of POWER with VOLTAGE and Current,

We have,

P = I × V

= 25/10 × 12

= 30 Watts

Therefore Power = 30 watts

Answer:

10√2 m/s

According to LAW of CONSERVATION of Linear momentum

MV = m1v1 + m2V2 + m3v3

V= 0

0 = 40i + 40j + 4v

v = -10I -10j

|V| = 10√2

1380 m is your answer

explaination:

TIME = 8S

SPEED = 345 ms

beacause of echo we will TAKE it as 2d,

THEN WE KNOW THAT D = SPEED × TIME

THERFORE,2D=S×T

2d = 345 × 8

d= 345×8/2

HENCE,

d = 345 × 4

then,

d = 1380m
