Its quite hard to give you facts over this but just type into google facts about the sonar/lunar eclipse.
Answer: 0.01 m
Explanation: The formulae for capillarity rise or fall is given below as
h = (2T×cosθ)/rpg
Where θ = angle mercury made with glass = 50°
T = surface tension = 0.51 N/m
g = acceleration due gravity = 9.8 m/s²
r = radius of tube = 0.5mm = 0.0005m
p = density of mercury.
h = height of rise or fall
From the question, specific gravity of density = 13.3
Where specific gravity = density of mercury/ density of water, where density of water = 1000 kg/m³
Hence density of mercury = 13.3×1000 = 13,300 kg/m³.
By substituting parameters, we have that
h = 2×0.51×cos 50/0.0005×9.8×13,300
h = 0.6556/65.17
h = 0.01 m
The escape speed for a spacecraft at the surface of a planet of mass M and radius R is:
where G is the gravitational constant. We can use this formula to solve both parts of the problem, using the data of Jupiter and Mars.
a) Mars:
Mars mass is
, while Mars radius is
, so the escape speed of the spacecraft at Mars surface is
b) Jupiter:
Jupiter mass is
while its radius is
, so the escape speed at its surface is

Answer:
In a building, heat rises. By putting the insulation in the ceiling heat will rise and get trapped at the top and fill up the entire room. The purpose of insulation is to minimize the transmission of heat within the walls, floors, and ceilings. By minimizing the transmission of heat, you not only keep the room warm but you also lower your electricity and heat bill.
