Answer:
True
Explanation:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
Distance is 50 km
Displacement is 10 km
<u>Explanation:</u>
Given:
Distance toward south, x = 25 km
Distance towards west, y = 10 km
Distance towards north, z = 15 km
(a) Total distance, D = ?
Total distance, D = x + y + z
D = 25 + 10 + 15
D = 50km
(b) Displacement, d = ?
Displacement = final position - initial position
= 10 - 0 km
= 10km
Answer:
1.05045 kg/m³
Explanation:
= Density of air = 1.26 kg/m³
= Density of hot air
= Mass of balloon = 539 kg
g = Acceleration due to gravity = 9.81 m/s²
v = Volume of air in balloon = 
The net force on the balloon will be
Also
The density of hot air inside the envelope is 1.05045 kg/m³
