None of the above are the name of an air mass. This is probably a trick question.
Bulbs c and b would still be screwed in if they were in to begin with and bulbs A, D, and E. would be unscrewed
A freedom struggle (movement) is any organized effort within a society to promote, or attain, liberation or independence, based on social, political, economic, religious, or other ideological grounds.
Hope this helps! ;)
You need to divide the motion into its component: vertical and horizontal motion.
The time taken to fall vertically from the cliff is equal to the time taken to move horizontally.
Using the vertical component, which is an accelerated motion with an initial velocity equal to zero, we can solve for t:
h = 1/2 · g · t²
t = √(2·h / g)
= √(2·50 / 9.8)
= 3.2 s
Horizontally, it is a constant motion:
d = v · t
= 20 · 3.2
= 64 m
The ball will strike the ground at a distance of 64 meters from the cliff.
Explanation:
object D would be the hardest to stop, it has more mass, thus it has a higher momentum than the others, requiring a larger force to stop
