Correct Answer - B
Testa is the edible part in pomegranate. It is not formed if fruits aw produced by parthenocarpy (no seeds will be formed). Fruits of banana, grape and orange have seeds, so mduced parthenocarpv in these fruits is beneficial
Correct Answer - B
The magnitude of induced emf is directly proportional to the rate of change os magnetic flux. Also, induced charge is `dq=-(dphi)/(R)`, which is independent of time.
Correct Answer - B
The average value of alternating emf `E=E_(0)sinomega` t over a positive half cycle is
`E_(av) half cycle =(2E_(0))/(pi)=0.6369`
Percentage of `E_(av)=0.6369xx100=63.69%`
Also rms value of emf is...
Correct Answer - C
Geocarpy refers to the ripening of fruits underground. In the case of ground nut, the young fruits are pushed into the soil as a result of post-fertilisation...
Correct Answer - A::C
Given equation is `x^(2) + 2x sin(cos^(-1) y) + 1 =0`
Since x is real, `D ge 0`. Therefore,
`4(sin(cos^(-1)y))^(2) -4 ge 0`
or `(sin(cos^(-1)y))^(2) ge 1`...
