Answer 1

Question :-

Two boys starting at the same point, walk in opposite directions for x metres, turn right and walk another y metres, and turn right and walk another x metres. What is the distance between them?

A) 2 y + 2 x

B) 2 y ✔✔

C) 2 x

D) y + x

Answer :-

$\boxed{\boxed{\large{\sf{\pink{Option\: B) 2 \: y }}}}}$

Explanation :-

♠︎ While dealing with the questions related to Distance, and direction it is convenient to draw figures according to the given information.

Refer to the figure attached

✤ O is the starting point from where two boys started walking.

✤ From O Boys walked a distance x metres such that OA = OP = x metres.

✤ Then they turned right according to their respective positions and walked a distance y metres such that AB = PQ = y metres.

✤ Again they turned right accord to their respective positions and walked a distance of x metres, i.e, BC = QR = x metres.

✤ Currently they are standing at C and R and we have to find distance CR .

✤ As we can conclude in the figure that

AB + PQ = CO + RO = y + y = 2 y metres.

● Hence, the distance between the two boys is 2 y metres.

Answer 2

Answer:

Answer:

Power (P) =2kw =2000w

Power(P) in watts =J/s

1 watts = 1 J/s

Therefore , 2000w = 2000 J/s

One minute = 60 seconds

Power (P) is also given by

P= Work done ( W )/( t ).....( 1 )

w = mgh

Height (h) = 10m

g = 9.8m/s2

Applying all the above data in equation( 1 )

P=(m×9.8×10) / 60

Therefore, m = 1224.489 Kg

Thus , the electric pump can lift 1224.489 Kg , every minute to height of 10 m.
