b. An apartment with ten floors has a water supply design as shown in the figure. If three people on the 1st, 3rd and 5th floors open their taps at the same time, where will the pressure be the maximum?
Answer :
The pressure in the first floor will be the maximum.
Because,
We can see in the figure that the first floor is at bottom. The more the depth, more the pressure. so it is the deepest, that's why there will be more pressure.

Q. 1 observe the figure and fill in the blanks .
1) The parachute jumper falls because of force of gravitation
2) the parachute helps to slow his fall by creating opposite force of 600 of air resistance.
3) the resultant force is 200
4) the resultant force is towards ground.
Q.2 An apartment with 10 floors has a water supply design as shown in the figure . if three people on 1st 3rd and 5th floors open their taps at the same time where will the pressure be the maximum?
Answer :
1st floor will have maximum pressure.
This is because pressure increases, as dept increases. In other words, the more the depth, more the pressure. As we can see in the figure that the first floor is at the very bottom, we know that it is the deepest, and thus, there is more fluid pressure there.
