The design of a new computer processor requires that electric current be carefully controlled. Why might an engineer want to use a metalloid when designing a new computer processor?

Answers

Answer 1
Answer:

Answer choices are:

A.) Metalloids are amphoteric.

B.) Metalloids are semiconductors.

C.) Metalloids are brittle.

D.) Metalloids are shiny.

____________________________________________________________

Correct answer choice is:

B.) Metalloids are semiconductors.

Explanation:

The form, design, and implementation of CPUs have replaced over the track of their past, but their primary process continues almost constant. Principal parts of a CPU involve the arithmetic logic unit (ALU) that executes arithmetic and logic operations, processor registers that provide operands to the ALU and save the results of ALU operations and a control unit that organizes the fetching and performance of directions by directing the coordinated operations of the ALU, registers and other elements.

Chemical weathering occurs more rapidly in what kind of climates?

Answers

The water alone can perform chemical weathering with the aid of other chemicals which usually form acids that breaks the internal composition of the material. Hot & cold climates usually cause the flaking the outer layers of a rock (thermal expansion) but it belongs to physical weathering.
However, Physical and chemical weathering work together to disintegrate the rock more easier.
I can't specify a climate well because chemical weathering doesn't involve climate too much.

The radius of an atom of gold (Au) is about 1.35 Å.How many gold atoms would have to be lined up to span 9.5 mm ?

Answers

Answer : The number of gold atoms will be, 3.52* 10^7

Explanation :

First we have to determine the diameter of an atom of gold.

Diameter=2* Radius

Given :

Radius of an atom of gold = 1.35\AA

Diameter=2* 1.35\AA=2.7\AA

Conversion used :(1\AA=10^(-7)mm)

Diameter=2.7\AA=2.7* 10^(-7)mm

Now we have to calculate the number of gold atoms.

\text{Number of gold atoms}=\frac{\text{Span length}}{\text{Diameter of an atom of gold}}

\text{Number of gold atoms}=(9.5mm)/(2.7* 10^(-7)mm)=3.52* 10^7

Therefore, the number of gold atoms will be 3.52* 10^7
Two radius of an atom is equal to the diameter. Adding up all the diameter of  the atoms, it should be equal to 9.5 mm. Therefore, we simply convert the units to the same units then divide 1.35 A to 9.5 mm. We calculate as follows:

no. of atoms = 0.0095 m / 1.35x10^-9 m = 7037037 atoms 

Hope this answers the question. Have a nice day.

Explain the connection between Earth's magnetic field and iron.

Answers

The Earth's magnetic field is somewhat caused by the composition of the earth's core which is rich in iron minerals. There is a solid inner core that is made of iron which makes up to 2/3 of the moon's size. The charged metal of the iron produces electric currents, consequently resulting to Earth's magnetic field.

Answer:

The Earth's magnetic field is caused by how the earth's core is made. The earth's core is full of iron, especially in the inner core. That inner core is charged metal that produces electric currents that causes Earth's magnetic field. So because the core has iron, we have a magnetic field.

Which of these factors are experienced by a space shuttle in orbit? Check all that apply. A. gravity
B. air resistance
C. friction
D. inertia
E. centripetal force

Answers

Answer:

Gravity, inertia, centripetal force

Explanation:

Gravity: A space shuttle in orbit experiences gravity not just from the planet it is orbiting but from other celestial bodies too

Air resistance: There is no atmosphere in space so the shuttle experiences no air resistance

Friction: There is no atmosphere or surface that it is moving on so the shuttle experiences no friction

Inertia: Any body that is moving or stationary experiences inertia, the resistance to change in velocity whether it is moving or stationary

Centripetal force: The shuttle is in orbit, what keeps it in orbit is the centripetal force towards the center of the body it is orbiting
A. gravity (of any planet/star/celestial body around )

D. Inertia

E. Centripetal force
