A satellite is revolving round the earth with a speed of 7.6 km/s. What is your estimation of the height of the satellite from the earth surface, consider the mass of the earth $$= 6.10^{24}$$ kg and radius of the earth = 6400 km
The maximum number of intensity minima that can be observed in the Fraunhofer diffraction pattern of a single slit (width 10 $$\mu$$ m) illuminated by laser beam (wavelength 0.630 $$\mu$$m) will be
Consider the following statements:
(A). The output of a linear OP-amp circuit has the same shape as the input signal.
(B). At no time during the cycle does the OP-amp go into saturation.
(C). Non-inverting amplifier possess low input impedance and high output impedance.
(D). One advantage of inverting amplifier is that its voltage gain equals the ratio of the feedback resistance to the input resistance.
