Q 1 / In a sapphire laser with a wavelength of 694.3 nm, the sapphire crystal is 0.1 m long and the reflectivity of the two-time mirrors is 97% and 90%. If the amount of loss is 10% for each complete cycle. Calculate the wind (gain) coefficient of the threshold? And what is the inverse qualification to obtain such a profit coefficient if you know that n= 1.82 change in frequency v = 3×10^12 HZ and the second residence time is equal to 200×10^-6sec​

The mass of a bowling ball is 10 kg and the mass of a ping pong ball is 0.015 kg. if the two objects are 5 meters apart, what is the gravitational force ?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
