The correct answer to the question is: B) They appear to bend at the surface due to refraction.
EXPLANATION:
When light moves from optical rarer medium to optical denser medium, the light rays are bent towards the normal at the point of incidence on the refracting surface. If the order is changed, then the way will be away from the normal.
This property of light is known as refraction which is due to the fact that light has different velocities in different media.
As per the question, the object appears to be bent when it is submerged in water. Actually the object is not bent. Its the light from object which is bent at the air-water interference.
Hence, the correct answer of this question is refraction.

Explanation:
In a covalent bond, valence electrons are shared; in an ionic bond, valence electrons are transferred.
B.
In a covalent bond, valence electrons are transferred; in an ionic bond, valence electrons are shared.
C.
In a covalent bond, outer electron orbitals are shared; in an ionic bond, outer electron orbitals are transferred.
D.
In a covalent bond, outer electron orbitals are transferred; in an ionic bond, outer electron orbitals are shared.
Answer:
Atoms form two types of bonds: ionic bond and covalent bond. In a covalent bond, valence electrons are shared; in an ionic bond, valence electrons are transferred.
Explanation:
Therefore, the answer is A
b. in non-accelerated motion.
c. free from Earth's gravity.
Answer: B
Explanation:
When in orbit, a satellite is hold in position thanks to, between others, the earth's gravity. So the C option is discarded.
A projectile is an object thrown by the exertion of some force, like a bullet or a cannonball.
A satellite is placed in some orbit, so he can rotate the earth. The movement of the satellite is non-accelerated motion, because the only forces that act on the satellite are the forces that hold him in orbit.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion and is influenced by Earth's gravity.
When in orbit, a satellite such as the space shuttle is in non-accelerated motion.
It is not simply a projectile because it is continuously under the influence of Earth's gravity.
However, it is not completely free from Earth's gravity as it continues to be pulled towards the Earth.
