Answer:
The metal Harvey should use for reflective coatings in telescope mirror is;
C. Aluminum
Explanation:
In a telescope, the mirror of the telescope is usually made of a temperature-resistant and strong glass, while the reflective coating of the mirrors is made usually from aluminum. A protective coating often composed of silicon dioxide is placed n the top of the reflective coating
Aluminum is used in a telescope, rather than the silver, which is the most reflective material, because silver requires special conditions to be able to work, and silver tarnishes when exposed to air containing sulfur, and silver is susceptible to corrode.

what are two items that are used to visualize how a building should be built and what materials must be used?
Answer:
shut up
plzzz
Explanation:
Two items that are commonly used to visualize how a building should be built and what materials must be used are: Architectural drawings and building models.
What are Architectural drawings?An architectural drawing, also known as an architect's drawing, is a technical drawing of a structure that falls under the definition of architecture.
Architectural drawings are detailed technical drawings that show a building's layout, dimensions, and specifications, including the location of walls, doors, windows, plumbing, electrical systems, and other features.
Building models are physical or digital representations of a structure that are frequently created with computer-aided design (CAD) software or 3D printing technology.
They enable designers, builders, and clients to visualize the structure in three dimensions and may include details such as the texture and color of building materials, the placement of windows and doors, and the layout of interior spaces.
Thus, these are the two basic items that are used to visualize how a building should be built and what materials must be used.

If there are four (4) bulbs in a parallel circuit and one bulb stops working in the
circuit, will the other bulb(s) still light? Explain why:
Answer:
Explanation:
Remark
Parallel Circuitry means that there is more than one path that the current can follow. In a series circuit, the current can follow only 1 path. So in a series circuit, if one bulb burns out, none of them work.
But the answer to your question is that in a parallel circuit, because there are many paths that can be followed, nothing changes except if you want a bulb to light up and it burns out, you have to replace it.

A gas metal arc welder is also known as a _____ welder.
A) TIGB) GTAWC) GMAWD) Resistance spot
Answer:
GMAW
Explanation:
It's literally the initials of that type of welding
The correct option is C. A gas metal arc welder is also known as a GMAW.
An electrical arc is used as the energy source in the gas metal arc welding (GMAW) technique, which is a type of fusion welding. The consumable filler metal in gas metal arc welding is also the electrode. The molten weld puddle is shielded by an external shielding gas.
What is GMAW and GTAW?In Gas Metal Arc Welding (GMAW), a consumable electrode is used. This causes the electrode material to melt and deposit on the weld bead. Because a non-consumable electrode is used during GTAW or TIG welding, no electrode material is deposited on the weld bead.
Gas tungsten arc welding (GTAW), commonly referred to as tungsten inert gas (TIG) welding, is a type of arc welding that uses an inert tungsten electrode to create the weld. For joining magnesium and aluminum, tungsten inert gas (TIG) welding saw an overnight success in the 1940s.
