Answer:
496.57492 kg/m³
Explanation:
= Atmospheric pressure = 101300 Pa
= Density of water = 1000 kg/m^3
= Height of water = 21.8 cm
= Height of fluid = 30 cm
g = Acceleration due to gravity = 9.81 m/s²
= Density of the unknown fluid
Absolute pressure at the bottom
The density of the unknown fluid is 496.57492 kg/m³
Explanation:
a) Balloon is being thrown down and is speeding up;
mg >
b) Balloon is in the air on its way down and moving with constant speed.
=mg
c) The Balloon is on the ground and rest instantaneously
mg = Normal
d) Balloon is moving slowly downward;
e) Because, at the peak of trajectory drag force is 0.
Drag force = 0
Answer:
The distance reached is 14.3 m.
Explanation:
To find the distance reached by the diamond first we need to find the flight time:
Where:
h: is the height = 10m
g: si the gravity = 9.81 m/s²
Now, we can find the distance reached:
Where:
is the initial horizontal velocity = 10 m/s
Therefore, the distance reached is 14.3 m.
I hope it helps you!
