He inner surface of a cone coated by a reflecting layer forms a conical mirror. a thin incandescent filament is stretched in the cone along its axis aphe minimum angle o of the cone for which the rays emitted by the filament will be reflected from the conical surface not more than once is greater than or equal to 120°. b) ifangle ofcone is less than 120° the rays from the filament will be reflected from the conical surface not more than once c) forany angle of cone multiple reflections of the rays from filament occurs d) lf angle ofcone is less than 120° the rays from the filament will be reflected from the conical surface more than once

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
