Answer: energy source, path, and load
Explanation:
Answer:
1) The wires
2) A component e.g. light
3) A power source
Explanation:
A power source is a basic part of a circuit because if the circuit doesn't have a power source, how will the electrons flow around? . A component is a basic part of a circuit because what's the point of having a circuit without something happening for example a light flashing or a motor turning. Finally, the wires are important because they carry the electrical charge for the component to turn on so if there is no wires there is no electrical flow being carried along
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

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.

Determine the ratio of the resistivity of pure water to silver?
3 x 10 11.1
1:3
1:3 x 10 11.1
Answer:
[tex]3 \cdot 10^{11} : 1[/tex]
Explanation:
Silver is a generally excellent conductor, this implies its resistivity is low (from table, we can check the exact worth i.e [tex]\rho_s = 1.6 \cdot 10^{-8} \Omega m[/tex])
Pure water, rather, is an extremely awful conductor, this implies its resistivity is exceptionally high, of order of [tex]k \Omega \cdot m (10^3 \Omega m )[/tex]
Indeed, even without knowing the exact estimation of the pure water resistivity, we can appraise the proportion between the pure water resistivity and the silver resistivity by looking at the two orders of magnitude:
[tex]r= \frac{10^3 \Omega m}{10^{-8} \Omega m} \sim 10^{11}[/tex]
Therefore, we can say that the correct answer is
[tex]3 \cdot 10^{11} : 1[/tex]

2 A sailboat on a lake sails 40. meters north and
then sails 40. meters due east. Compared to its
starting position, the new position of the sailboat
is
(1) 40. m due east (3) 57 m northeast
(2) 40. m due north (4) 80. m northeast
Answer: 3
57m north east
Explanation:
Given that the boat sails 40. meters north and then sails 40. meters due east. The new position will be known by using pythagorean theorem.
P^2 = 40^2 + 40^2
P^2 = 1600 + 1600
P^2 = 3200
P = square root (3200)
P = 56.6 m
P = 57 m (approximately )
Therefore, the new position of the sail boat will be 57 north east
Compared to its starting position, the new position of the sailboat is 57 m northeast
The given parameters;
initial displacement of the sail boat, x₁ = 40 m north
final displacement of the sail boat, x₂ = 40 m east
The new position of the sail boat when compared with the starting position is the total displacement of the sail boat.
A sketch of the sail boat displacement;
↑ → → → → → → 40 m
↑
↑40 m
↑
The hypotenuse of this right triangle is the total displacement of the sail boat.
[tex]R^2 = 40^2 + 40^2 \\\\R^2 = 3200\\\\R= \sqrt{3200} \\\\R = 56.57 \approx 57\ m[/tex]
The direction of the sail boat is northeast
Thus, compared to its starting position, the new position of the sailboat is 57 m northeast

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".

Explanation:
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

what is an example of a compressional wave?
Answer:
The wave front expanding out from an explosion is possibly the most dynamic example of a compressional wave. And a pulse of compressed air can transfer a LOT of energy. ... For a literal "compression wave" visualize accelerating a boat across the water, compressing the water it encounters into a "bow wave".
Sound is an illustration of a compressional wave. Mechanical waves like sound waves need a medium to travel through, such air, water, or solids.
A sound wave undergoes compressions and rarefactions as it passes through a medium.
Particles in the medium move parallel to the wave's propagation direction during a compressional wave.
When particles are close to one another, compression regions arise in the case of sound waves, creating high-pressure zones.
Following these compressed zones are rarefactions, when the particles are dispersed and low-pressure areas develop.
Thus, sound is an example of a compressional wave.
