Answer:
45 J
Explanation:
Work done = force × displacement
(<em>displacement</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>shortest</em><em> </em><em>distance</em><em> </em><em>the</em><em> </em><em>object</em><em> </em><em>travels</em><em> </em><em>when</em><em> </em><em>a</em><em> </em><em>force</em><em> </em><em>is</em><em> </em><em>applied</em><em> </em><em>on</em><em> </em><em>it</em><em>)</em>
W = 15 × 3
= 45 J
[Note: While using the formulae, all quantities must be in their SI units.]

Explanation:
Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)
