Answer:
Power = 251.9 Watts
Explanation:
Power = Work Done / Time taken
Power = 3441 / 13.66
Power = 251.9 Joule / Second
Power = 251.9 Watts
Answer:
Graph C
Explanation:
This is the answer because it is the only one that shows the vehicle accelerate to a constant speed before stopping and slowing down.
Answer:
110 meters is the distance where they will intersect
Explanation:
given,
liquid density = 1900 kg/m³
distance of upper hole = 19 m
distance of lower hole = 117 m
acceleration due to gravity = 9.8 m/s²
the speed at each point
for upper hole
v = 19.29 m/s
lower hole
v = 47.88 m/s
The path for each is parabolic
x = v t
we get
upper hole
lower hole
y for upper hole = 80 + y for lower hole


x = 109.32 meters
110 meters is the distance where they will intersect
