. Two containers of volumes V 1 and V 2 are connected by a small tube with a valve. Initially, the valve is closed and the two volumes contain monoatomic gas at pressures P 1 and P 2 , and temperature T 1 and T 2 respectively. The initial values are given by: V 1 =24.942 I , P 1 =3.13 bar , T 1 =40^ C , V 2 =49.884 L , P 2 =24.01 bat , T 2 =70^ C . The valve is then opened, and an amount of heat of 111.68 k. J is acquired by the gas. 2. Calculate the final pressure of the gas

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?

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

It is really hard for me right know
