Answer:
The length of open-open pipe needed is 6.23 m
The length of open-close pipe needed is 3.11 m
Explanation:
Fundamental frequency for standing wave mode of an open- open pipe is given by
where v is the velocity and L is the length
The length of open-open pipe needed is
Fundamental frequency for standing wave mode of an open- close pipe is given by
The length of open-close pipe needed is
Answer:
600 and 1500 [ohm
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is the product of the current by the resistance, so we have:
V = I*R
where:
V = voltage [V]
I = current [amp]
R = resistance [ohm]
<u>Therefore:</u>
R = V/I
R1 = 60/(40*10^-3) = 1500 [ohm]
R2 = 60/(100*10^-3) = 600 [ohm]
So the resistance should be among 600 and 1500 [ohm]
Answer:
We will use Potential Energy Formula
Potential Energy = mass × gravitation × height
PE = 0,55 × 10 × 4
PE = 22 J (A)

Answer:
0.00098 N
Explanation:
The weight of an object is given by:
where
m is the mass of the object
g is the gravitational acceleration on the planet
In this problem, we have:
is the mass of the honeybee
is the acceleration due to gravity
Substituting into the equation, we find:
