On Monday a cargo plane pilot calculated his plane must go 125 miles per hour down the runway in order to become airborne One Tuesday, the same pilot, in the same plane and using the same runway calculated he must go 105 miles per hour in order to become aiborne The weather conditions were the same both days Which choiceBEST explains why the plane's speed had to be higher on Monday? A The plane had less cargo less inertia, and needed less lif force on Monday compared to Tuesday B The piane had less cargo more inertia, and needed less lif force on Monday compared to Tuesday С The plane had more cargo less inertia and needed less lift force on Monday compared to Tuesday The plane had more cargo more inertia, and needed more lift force on Monday compared to Tuesday​

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.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
