strongly, why can it not interact with a life time of 10 - 23 5& instead of 10~ sec ?

(८५) because they associate with the creation of strange particles and they immediately
decay

(8) because they are produced in pairs, each one decays into ordinary particles through
weak interactions

(C) because the quantity hyper charge is conserved in strong interaction
(D) because the quantity strangeness remains constant in fast particle reaction

How much [सिरे and U2 will be lost in 1 year by o« decay ?
(A) 98162 pg ಈ) 15220 (C) 6870774 pg (D) 70:152 ‏چ٥‎

In liquid drop model, if A, Z and N are mass, atomic and neutron numbers respectively, then
the deficit in binding energy is proportional to :
(ಸಿ) A-Z/N ठ) (N-Z)3/A (2) (^-22)2/4 (D) both (B)and (O)

The frequency response of an op amp is indicated by plotting :
(A) the magnitude of transfer gain

(B) the phase-lead angle as a function of frequency

(೮) both (A) and (0)

(D) none of these

The h parameters of an npn transistor are h;,=1000 Q, h, = negligible, hy, =60 and
h,e=12%10" 8 mho, the power gain for a CE amplifier if Ry = 10000 4):

1f A is the Hime delay in a shift register with clock period T, the pulse train at the output of an
‘n’ register is delayed by :

(५) (-१)/^ (8) "-1/^ (©) (-1/2) (D) (೧-1)
The parameter which measures the performance of FET is :

(A) trans conductance (ए) drain current

(9) gate voltage (12) input resistance

Though connecting solar cells in parallel will yield high current, the significant problem exist

with the parallel connection is :

(ക) the drift current produced will cause a power loss

(8) ‏ما عط‎ value of fill factor may reduce the power because of reverse biasing

(C) the shadow effects will cause power 1055 because of reverse bias applied by their
illuminated cells

(2) none of these
