Only 2,3,4 are true
Explanation:
Bosons Particles are particles that condense to the same state. Bosons particle have integral spin like 0 , ,
,
, etc. Bosons particles always have asymmetric wave function and there is exchange of particles.
1) It does not obey Fermi_ Dirac statistics
2) It obeys Bose-Einstein statistics
3) The object can have intrinsic spin
4) Yes the Bosons particle is always symmetric with exchange of particles
5) No Bosons particle are symmetric and not asymmetric
Answer:
a) t=24s
b) number of oscillations= 11
Explanation:
In case of a damped simple harmonic oscillator the equation of motion is
m(d²x/dt²)+b(dx/dt)+kx=0
Therefore on solving the above differential equation we get,
x(t)=A₀
where A(t)=A₀
A₀ is the amplitude at t=0 and
is the angular frequency of damped SHM, which is given by,
Now coming to the problem,
Given: m=1.2 kg
k=9.8 N/m
b=210 g/s= 0.21 kg/s
A₀=13 cm
a) A(t)=A₀/8
⇒A₀ =A₀/8
⇒
applying logarithm on both sides
⇒
⇒
substituting the values
b)
, where
is time period of damped SHM
⇒
let be number of oscillations made
then,
⇒
