Question: 1-8 U-Science-Gr6-Unit3-PBT-CBT (2020-21)
Spring 1 and Spring 2 are the same type of spring. Both springs were pushed or compressed into different positions and clamped into place.
Which spring has less potential energy?
O Spring 1
o Spring 2
O Spring 1 & Spring 2 have the same amount of energy.
You cannot tell unless you know what the springs are made of.

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?

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .
