Answer:
The sheets move toward each other and the gap narrows
Explanation:
When two sheets are arranged or hanged in such a way, there is a small gap in between the two parallelly hanging sheets. This gap is filled by the surrounding air.
Now if we blow gently in between the gap of the two sheets, we will observe that the two sheets move towards each other and will come closer thereby narrowing the gap in between them.
This is because as we blow through the gap, partial vacuum is created in between the sheet for a short time. So this vacuum is filled by the air surrounding the two sheets thereby forcing the two sheets closer.

Swim Test:
1. Jump into the pool, submerge fully, return to the surface and immediately begin swimming without pushing off the wall.
2. Swim in a horizontal position on top of the water using a forward crawl or breaststroke. The swimmer's arms must achieve full extension on every stroke, and he or she must maintain one or both of the strokes for the full 25-yard swim. Pausing is only allowed when the swimmer is rotating or turning to breathe.
3. Exit the pool without assistance using either the wall or pool ladder.
4. do 4 laps in 3 minutes
Answer:
Explanation:
Given
mass of first child 
mass of second child 
Distance between two children is 
Suppose light weight child is placed at a distance of x m from Pivot point
therefore
Torque due to heavy child 
Torque due to small child 
Net Torque about Pivot must be zero
Therefore 
Answer:
N₁ = 1800 turns
So, the side of the transformer that plugs into the outlet has 1800 turns.
Explanation:
The transformer turns ratio is given by the following equation:
V₁/V₂ = N₁/N₂
where,
V₁ = Voltage of outlet = 120 V
V₂ = Device Voltage = 3 V
N₁ = No. of turns on outlet side = ?
N₂ = No. of turns on side of device = 45
Therefore,
120 V/3 V = N₁/45
N₁ = (40)(45)
<u>N₁ = 1800 turns</u>
<u>So, the side of the transformer that plugs into the outlet has 1800 turns.</u>
