`f(m)<0.f(x)=ax^2-bx+c,m` lies between the roots and `f(m_1)f(m_2)<0,` then one of the roots will lies between `m_1and m_2`

A: The bandwidth of a modulated signal is 2f_(m) in amplitude modulation, where f_(m) is the frequency of the modulating signal. R: In case of amplitude modulation the frequency of a modulated signal is equal to the frequency of the carrier wave.

If f is m.i.then -f,(1)/(f) are m.d

Let f be real valued function from N to N satisfying. The relation f(m+n)=f(m)+f(n) for all m,n in N . If domain of f is first 3m natural numbers and if the number of elements common in domain and range is m, then the value of f(1) is

Eddy current loss is directly proportional to ( f=" frequency " "B_(m)= maximum flux density")(a) f^(2) and B_(m)^(2) (b) f and B_(m) (c) f and B_(m)^(2) (d) f^(2) and B_(m)

F alpha (m_(1)m_(2))/(d^(2)) means F= _____________.
