Search Results<span>Use BFS to determine the length of the shortest v-w-path. Then use DFS to find thenumber of the v-w-shortest paths such that two nodes are connected and the length of path equals to the output of BFS. But the running time of this plan is O(m+n)+O(m+n). Also I've tried to modify the Dijkstra algorithm.</span>
Q: What does potential energy depend on?
A: Pontential energy depends on the mass of an object and it's distance.
Answer:
Gravitational potential energy (GPE) = 107.8J
Explanation:
Gravitational potential energy (GPE) = mgh
Where mass(m) = 11kg
Acceleration due to gravity(g) = 9.8m²/s
height = assumed to be 1m
Force(F) = mg
Force(F) = 11×9.8 = 107.8N
Gravitational potential energy (GPE) = 107.8×1
= 107.8J
Answer:
1.42 s
Explanation:
The equation for free fall of an object starting from rest is generally written as

where
s is the vertical distance covered
a is the acceleration due to gravity
t is the time
On this celestial body, the equation is

this means that

so the acceleration of gravity on the body is

The velocity of an object in free fall starting from rest is given by

In this case,
g = 20.08 m/s^2
So the time taken to reach a velocity of
v = 28.6 m/s
is
