You have been assigned the 192.168.1.0 /24 network. you need to establish 8 subnets. determine the number of bits that need to be borrowed. write out, in both binary and decimal formats, the subnet mask needed to create 8 subnets for the 192.168.1.0 network. look at your subnet mask and identify which octet contains the split between the network portion and the host portion of the address and subtract that number from 256 to calculate the subnet block size.

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
