Answer:
there are 5 hydrogen atoms in that formula
Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+
+
=
+
+
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4 
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5 
= 3.6 m
Put all the values in equation (1) we get,
⇒
+
=
+
+ 3.6
⇒ 0.294 =
+ 0.6244 + 3.6
⇒
= 0.294 - 0.6244 - 3.6
⇒
= - 3.9304
⇒
= - 38557.224 pascal
This is the value of gauge pressure at outlet.
Answer:
Got it from g00gle: Similarly, electrons flow more easily through a thick wire than they flow through a thin wire of the same material. Resistance is greater in a longer wire because the charges travel farther. As temperature increases, a metal's resistance increases because electrons collide more often.
Explanation:
Answer:
The value is 
Explanation:
From the question we are told that
The diameter is 
The length of the wire is 
Generally the cross sectional area of the copper wire is mathematically represented as

=> 
=> 
Generally the resistance is mathematically represented as

Here
is the resistivity of copper with the value 
=> 
=>
