In the distant future, a new planet has been discovered around a nearby Sun-like star. The following information is known about this planet: 1) It has
a density of 4.1 compared to water; ii) its orbital semi-major axis is 1.7 AU;
iii) it has a very thin CO2 atmosphere; iv) imaging of the surface shows an
extensive amount of cratering as well as no liquid water on the surface.
There is evidence of volcanic activity in the distant past. Determine the
following based on the above information:
a) What type of planet is this? (Terrestrial or Jovian)

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?

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Ajoint produces movement when its angle decreases. which type of movement is it?
