The diagram shows the schematic symbol of a transistor.
Which is the correct label for the part of the transistor
marked with an X?
Х
base
outlet
gate controller
electrical supply
Answer:
base
Explanation:
In the schematic symbol of a transistor, the arrow in the symbol indicates the direction of flow. There are three terminals namely, emitter, collector and base.
When you apply 0.7V from base to emitter you will turn the transistor ON and allow a current to flow from collector to emitter.
With the x in the picture the base must be indicated because all other answers do not make sense.
The correct label for the part of the transistor marked with an X is base.
What is transistor?A transistor is a semiconductor device used to amplify the electrical signals and power. The transistor is one of the important part of modern electronics. It is consist of semiconductor material, have three terminals for connection.

A bird sitting on a hinged perch takes off from the perch, pushing the perch
in the opposite direction. The momentum of the perch
Answer:
The momentum of the perch is equal to it's own momentum gather to take off
Explanation:
According to the Newton third law of motion which state that: in every action, there will be an equal and opposite reaction.
This is the law that helps us to walk, paddle boats e.t.c.
And momentum is always conserved. Therefore, the momentum of the perch is equal to it's own momentum gather to take off

6. To which of these abrasive disks can you
apply a water-coolant?
(A) Concrete
(B) Metal
Answer: its B
Explanation:
Metal abrasive disks are used as a water coolant. These are used mostly to slice stones and metals. Grit discs have several advantages over various kinds of discs. They have such a relatively fast cutting speed. The grit disc sander is not a hefty instrument that can be easily held when operating on a scaffold.
Steel cutting fluids are abrasive or peening mediums composed of iron particles. They are typically offered in two sizes (shot and grit) that suit various industrial applications. Since these grains are made from smashed steel shot, they have sharp edges and broken parts.Therefore, the answer is "Option B".

a baseball player throws 4 balls every 20 seconds. what is his throw frequency
Answer:
Frequency, f = 0.2 Hz
Explanation:
We have,
A baseball player throws 4 balls every 20 seconds.
It is required to find the frequency of the baseball.
Frequency of an object is defined as the number of times an event occurs. It is given by number of throws per unit time. It can be given by :
[tex]f=\dfrac{4}{20}\\\\f=0.2\ Hz[/tex]
So, the frequency of his throw is 0.2 Hz.

When waves traveling in the same medium meet, a new
wave may be produced. Use the slider to create the resulting
wave with the largest amplitude.
Answer:
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅
Explanation:
When several waves travel in the same direction, the process of adding them can take place.
y_total = ∑ [tex]y_{i}[/tex]
where
y_{i} = A_{i} sin (k x - w t + Ф)
with fi the phase of each wave
To produce the largest possible result, all waves must come with the same phase
y_total = (A₁ + A₂ + A₃ + A₄ + A₅) sin (k x - wt)
if there is any phase between the waves this value is less
if the sine function is ±, the amplitude of the total wave is
A_total = A₁ + A₂ + A₃+ A₄ +A₅

This is because since it is only half a second, it will only travel half of the distance that is shown in meters per second.
Two speakers create identical 240 Hz sound waves. A person is 1.47 m from Speaker 1. What is the MINIMUM distance to Speaker 2 for there to be destructive interference at that spot? (Hint: v= lambda f=343 m/s) (Unit = m)
Answer: 2.90 metres
Explanation:
Distance of speaker 2 =?
Distance of speaker 1 = 1.47m
Velocity = 343
f = 240Hz
For constructive interference to occur:
Difference in distance or path = wavelength
For minimum distance, n = 1
Distance 2 - distance 1 = nλ
Recall λ = v/f
V = Velocity ; f = frequency
Distance 2 - distance 1 = v/f
Distance 2 - 1.47 = (343/240)
Distance 2 = 1.429 + 1.47
Distance 2 = 2.899 meters
Minimum Distance of speaker 2 for their to be constructive interference = 2.90meters
Answer:
The answer would be 0.755415
