Answer:
see explanation
Step-by-step explanation:
Given
tan a =
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =
= 41 , thus
sin a =
= 
cos a =
= 
H= height of rockhopper penguin.
H= 45 - 24
H= 21 inches
Answer is reasonable because you have to take the height of the emperor penguin and subtract how much taller it is from it.
Answer:
Therefore the diameter of the hole is
m.
Step-by-step explanation:
Bernoulli's equation,

P₁ = P₂= atmospheric presser
= density
[since P₁ = P₂]



[
]
Here 


Here g= 9.8 m/s² , h = 10.4 m
The velocity of water that leaves from the hole
=
m/s
=14.28 m/s.
Given, the rate of flow from the leak is

Let the diameter of the hole be d.
Then the cross section area of the hole is 
We know that,
The rate of flow = Cross section area × speed



Therefore the diameter of the hole is
m.
