Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor toa. run at highest speed.
c. run at lowest speed.
b. run at medium speed.
d. stop immediately

Answers

Answer 1
Answer: The answer to the question stated above is letter a. run at highest speed.

Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to run at highest speed. If resistors are jumpered, the three-speed fan will over speed and probably burns out.

If a material is ductile, it is most likely a ____________ . Question 24 options: A. Metalloid B. Noble Gas C. Non-Metal D. Metal E. Ion

Answers

Answer: Option (A) is the correct answer.

Explanation:

It is known that metals are malleable and ductile. Whereas non-metals are neither malleable nor ductile.

On the other hand, metalloids are the elements which contain properties similar to both metals and non-metals.

Therefore, if a material is ductile, it is most likely a metalloid because it is not necessary that ductility is a property shown by metals only.

Wherease like non-metals, noble gases are also neither malleable nor ductile.

How can three resistors of resistances 2 ohm 3 ohm and 6 ohm be connected to give a total resistance

Answers

Explanation:

Three resistors of resistances 2ohm,3ohm, and 6ohm respectively.

Let R1=2Ω

⇒R2=3Ω

⇒R2=6Ω

● A total resistance of 4Ω from three resistors of given resistances. Firstly, connect the two resistors of 3Ω and 6Ω in parallel to get a total resistance of 2Ω which is less than the lowest individual resistance.

●When R 2 and R 3 are connected in parallel with

R1 in series we get

⇒1/R=1/R2+1/R3

⇒1/R=1/3+1/6

⇒1/R=1/2

⇒R=2Ω

●Hence, the total resistance of the circuit is 4Ω.

Select all that apply.There is no sound in the vacuum of space. Why?
Sound must travel through something that vibrates.
There is no energy in space.
There is no air to vibrate the human eardrum.
Space is too full of light energy.

Answers

Answer:

Sound must travel through something that vibrates.

There is no air to vibrate the human eardrum.

Explanation:

Waves can be divided into two types:

- Electromagnetic waves: these are waves produced by the oscillations of electric and magnetic field. This type of wave does not need a medium to propagate, so they can also travel through a vacuum

- Mechanical waves: these are waves produced by the vibrations of the particles in a medium - therefore, they do need a medium to propagate. Sound waves are part of this type, so they cannot travel through a vacuum.

According to these definitions, we can say that the correct choices are the following:

Sound must travel through something that vibrates. --> because they are mechanical waves

There is no air to vibrate the human eardrum. --> because they are mechanical waves
1. Sound must travel through something that vibrates.
and
3. There is no air to vibrate the human eardrum.
