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.
That object will move UNIFORMLY. That means it'll move in a straight line at constant speed.
Answer:
Free electrons
Explanation:
Copper is a lattice of positive ions with free electrons moving between them
Answer:

Required
Determine PCD and CPD
First, we need to calculate CPD
Since DPA is a straight line and CPA = 100;
We have that:
--- angle on a straight theorem
Substitute 100 for CPA
Subtract 100 from both sides
Next, we calculate PCD
We have that:
--alternate angle
In triangle PCD
--- angles in a triangle
Where
So, we have:
Subtract 136 from both sides
D. because the statue has a new chemical called patina. It is no longer copper.
