Explanation:
v = Speed of sound in air = 348 m/s
L = Length of tube = 2.17 cm
Fundamental frequency for a tube where one end is closed and the other end open is given by
The fundamental frequency of the canal is 4009.21658986 Hz
No, light can't cause the butterfly's wing's to glow. Explanation: Butterflies contain wings which are of different colors for attractiveness and also to show warning alarm for it's predator.
Explanation:
Given that,
Diameter of the gold wire, d = 0.84 mm
Radius, r = 0.42 mm
Electric field in the wire, E = 0.49 V/m
(a) Electric current density is given by :
And electric field is :
is resistivity of Gold wire
So,
(b) The potential difference between two points in the wire is given by :
(c) Resistance of a wire is given by :
Hence, this is the required solution.
