Two cylinders each with a 60 cm diameter, thatare closed at one end, open at the other, are joined to form asingle cylinder, then the air inside is removed. How much force does the atmosphere exert onthe flat end of each cylinder?
Suppose one cylinder is bolted to a sturdy ceiling. How many 90 kg football players would need to hang from the lower cylinder to pull the two cylinders apart

a

The force is  

b

The number is

Explanation:

From the question we are told that

    The  of each cylinder is  

     The mass of the players is  

Generally the cross-sectional  area of the cylinder is mathematically represented as

=>  

Generally force exerted on the flat end of each cylinder is mathematically represented as

Here P  is the atmospheric pressure with value  

So

=>    

Generally the weight of a single football player is  

=>    

=>    

Generally the number of player required to pull the two cylinders apart is mathematically represented as

=>    

=>    

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
