Answer:
lightning conductors/rods protect buildings by intercepting lightning strikes that may hit these structures.
Air conditioners pass air over cold coils known as evaporator pipes
Explanation:
Lightning rods are made of highly conductive metal, and offer a path of least resistance for any lightning strikes and are connected to longer wires that ground the charge.
air conditioners use a chemical compound called a refrigerant. the most common refrigerant used is r-134a also know as 1,1,1,2-Tetrafluoroethane. cooling systems use the low boiling points of these refrigerants to constantly cool and compress the chemical to continually move heat from the inside of the system to an external area.
The negative charges and positive charges in the wire are pushed in the opposite directions by the magnetic field
As migration grows, so does the distribution of people across areas, including the critical behavior of population extinction in some places under certain conditions.
<h3 /><h3>How does the population change due to migration?</h3>
If the migration continues rising as a consequence of a push to relocate, the desolate area can then become occupied once more.
As migration increases, so does the distribution of people across places, including the crucial behavior of population extinction for some places under a particular set of conditions.
Similar to this, migration will slow down aging in wealthy areas while speeding it up in underdeveloped ones.
Most nations and areas that experience population declines do so primarily as a result of the natural change, whereas regions that experience population gains do so mostly as a result of migration from outside of the city.
Hence, migration decreases the population.

Answer:
Length of the rod is 0.043m
Explanation:
Mass of the bell (M) = 36kg
Distance of the center of mass from pivot = 0.55m
Moment of inertia (I) = 36.0kgm²
Mass of clipper (m) = 2.8kg
Length of the bell to ring = L
The period of the pendulum with small amplitude of oscillation is
T = 2π √(I / mgd)
Where g = acceleration due to gravity = 9.8 m/s²
T = 2π √(36 / 36*9.8*0.55)
T = √(0.1855)
T = 0.43s
The period of the pendulum is 0.43s
To find the length of the Clapper rod for which the bell ring slightly,
T = 2π√(L / g)
T² = 4π²L / g
T² *g = 4π²L
L = (T² * g) / 4π²
L = (9.8* 0.43²) / 4π²
L = 1.7287 / 39.478
L = 0.043m
The length of the Clapper rod for the bell to ring slightly is 0.043m
