Explanation :
First considering Sid's statements, the description of tangential speed and centripetal acceleration are correct.
But for Centripetal force, the description is incorrect because centripetal force is always perpendicular to the velocity.
Sid's error can be corrected by the statement (b) i.e. "Centripetal force is perpendicular to the velocity of the satellite".
A grandfather paradox is a situation where individual travels to the past and then introduces a change which affects or contradicts the present.
<h3>What is a grandfather paradox?</h3>
A paradox is a situation or statement which involves two contradictions.
A grandfather paradox is a situation which is defined by the ability of an individual to travel to a time in the past usually before the birth of their grandfather and then introduces a change which affects or contradicts the present. For example, killing the grandfather to prevent their birth.
In conclusion, a grandfather paradox is is an event which contradicts the present as a result of a change done to the past.

Answer:
A) The hanging wall moves up.
C) The fault is at an angle.
D) The fault is caused by compression.
F) The plates are colliding.
Explanation:
the following statement are true about reverse faults.
A) The hanging wall moves up: a reverse fault is one that the hanging wall moves ups and the footwall moves down.
C) The fault is at an angle :reverse fault occur at less than 45 degree angle
D) The fault is caused by compression: reverse fault are cause by compressional stress where the hanging wall and footwall are pushed together.
F) The plates are colliding: the fault uses one or more plates that collide in movement.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
