<span>In order to make 4 complete revolutions in 4 seconds, the wheel must have a constant angular acceleration of 144° (or 2.5 radians) per square second, hence after 8 seconds the wheel will have made 14,4 revolutions, or 5184° in total.</span>
Answer:
Pressure at P point is given as
Explanation:
As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe
here we know that
L = 4 cm
r = 1 mm
Q = flow rate
now we have
For a standing wave if both ends are fixed, the wavelength must be such that the length of the string be an exact multiple of a half wavelength.
The longest wavelength must be such that the length of the string must be equal to half a wavelength, and therefore the wavelength must be double the length of the string; That is 240× 2 = 480 cm
The second longest wavelength must be such that the length of the string must be equal to a whole wavelength, so the second longest wavelength must be 240 cm.
The third longest wavelength must be such that the length of the string must be equal to 1.5 times the wavelength, so the wavelength must be 240/1.5 = 160 cm.
