A wagon (W) can be pulled by the players of two teams. Both Blue Team and Red Team have four players, one adult (A), a teenager (T), and
two children (C). The adult is the largest player, the children are the smallest players.
1. Even Steven.
If you arrange identical teams in the Tug of War, you'll get a tie. The net force is zero. The following are
examples of identical teams.
A-.W-A (Adult vs. Adult)
---W-
A-T-C-C-W-C-C-T-A
a. Describe three distinct ways to arrange the teams so that you get a tie even though the teams have
different numbers of players. These are non-identical, balanced teams. (To show distinct arrangements,
don't simply switch players on each side. For example, A-C---W-T and T---W-A-C are not distinct. (Nor do
they produce a tie.)

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

the answers would be

the first one and the second one
