Question

water level in a well was 20 m below ground level duringrainy season rain water collected in different water tank was drained into the well and the water level rises 5m above the previousvlevel the wall of well is 1m20cm high and pulley is fixed at a height of 80cm raghu wants to draw watrr fromnwell
find the height of pulley from the top of wall of well
find the water level of water in well from ground level in cm
find the leght of rope required to draw water from well
find the water level in well from ground level after rain​

Answer 1

Answer:

Step-by-step explanation:

we have been given that,

Wells height=1.20m

Pulleys height=0.80m

Hence, the required ropes length

=(20−5+1.20+.80)=(15+2)=17m​

Therefore, the minimum length of the rope is 17m.

Water level before rain = 20 m below ground level

water raised =5m

Water level after rain = -20+5 m

water level after rain =-15

WAter level is 15m below ground level

[-ve sign represents below ground level]
