Answer:
870 N
Explanation:
The expression for velocity of wave in a string is given below
v = , T is tension and m is mass per unit length .
m = 45 x 10⁻³ / 30 x 10⁻²
= .15 kg/m
Putting the given values in the equation
76 =
T = 76² x .15
= 866.4
870 N approx.
Answer:
The ratio of the Broglie wavelength of an electron to that of the proton is 42.85.
Explanation:
let λe be the Broglie wavelength of the electron and λp be the Broglie wavelength of the proton, Me be the mass of the electron and Mp be the mass of the proton. let h be the Planck constant, Kep be the kinetic energy of the proton and KEe be the kinetic energy of the electron
