Answer:
<em>The speed of the stream of air flowing through the leak is 340.754 m/sec</em>
Explanation:
Carefully applying the Bernoulli's equation the speed of the leak can be obtained. The attached images show step by step explanation of the question, while applying the Bernoulli's equation;
Answer:
2 x 10⁻³ volts
Explanation:
B = magnetic of magnetic field parallel to the axis of loop = 1 T
= rate of change of area of the loop = 20 cm²/s = 20 x 10⁻⁴ m²
θ = Angle of the magnetic field with the area vector = 0
E = emf induced in the loop
Induced emf is given as
E = B
E = (1) (20 x 10⁻⁴ )
E = 2 x 10⁻³ volts
E = 2 mV
Answer:
a)
Nm⁻¹
b)
Hz
c)
ms⁻¹
d)
m
e)
ms⁻²
f)
m
Explanation:
a)
= force required to hold the object at rest connected with stretched spring = 27 N
= stretch in the spring from equilibrium position = 0.2 m
= force constant of the spring
force required to hold the object at rest is same as the spring force , hence
inserting the values
Nm⁻¹
b)
frequency of the oscillations is given as
inserting the values
Hz
c)
= Amplitude of oscillations = 0.2 m
= angular frequency
Angular frequency is given as
rads⁻¹
Maximum speed of oscillation is given as
ms⁻¹
d)
maximum speed of the object occurs at the equilibrium position, hence
m
e)
Maximum acceleration of oscillation is given as
ms⁻²
f)
maximum acceleration occurs when the object is at extreme positions, hence
m
