Answer:
57.885.8 kg weight of the container
Explanation:
The volume of the balloon * density of water = buoyant force of balloon
volume of a sphere = 4/3 pi r^3
= 4/3 pi * (1.5)^3 = 14.14 m^3 <===balloon volume
Now, find the buoyant force on the container ALONE ....
5.8 * 2.6 * 2.8 * 1027 = 43 364 kg <===== buoyant force
Now add the buoyant force of the balloon to find the weight
43 364 + 14.14 * 1027 = 57885.8 kg
Answer:cross-sectional area, and thus surface area, increases the amount of air resistance an object experiences
Explanation:
Answer:
Explanation:
m = Mass of object =
mg = Weight of object = 20 N
g = Acceleration due to gravity =
v = Final velocity = 15 m/s
u = Initial velocity = 0
d = Distance moved by the object = 150 m
= Angle of slope =
f = Force of friction
fd = Work done against friction
The force balance of the system is
The work done against friction is .
