Alma is planning on joining the track team this year. In preparation for the season, Alma decides she wants to start running on her own to get in shape. The next day, Alma decides to work on short sprints instead of long-distance running. Explain how Alma’s body cells would obtain energy differently when she sprints than when she runs long distances. When would her body’s cells make energy more efficiently? Why?

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 electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
