It depends on the level of arousal
It will be refracted accordingly, based on Snell's law. In this case, the angle of incidence is smaller than the angle of refraction, and as it is traveling from a more dense to a less dense medium, it may undergo total internal reflection, provided that the angle of incidence is greater than the critical angle.
Smaller, because Mars is less massive and less dense than Earth.
Obtuse angle
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
Not necessarily, gravitational pull is dependant upon the mass of an object. A smaller object can have more mass than a bigger object (An extremely dense 1x1x1 cube has more gravitational pull than a less dense 3x3x3 cube that has less mass). Size has absolutely NOTHING to do with gravitational pull.
Bigger.
It would be smaller. The force on the particles will be the same. However, their bigger mass (inertia) will mean that their sideways acceleration is less than for lighter particles. They travel in a larger arc
An acute angle is less than 90 degrees, an obtuse angle is greater than 90 but less that 180 degrees. So acute is smaller
The larger the central atom is the less the hydrogens have to spread out (because the electron repulsions are smaller) and the smaller the resulting angle.
An acute angle is less than 90 degrees. it is smaller than a right angle.
an acute angle or something less then 90 degrees
An angle that is less than 90 degrees is known as an acute angle.
