Answer:

Zero

Explanation:

If an object has a constant velocity then its not increases its velocity therefore acceleration is zero

A transformer is to be used to provide power for a computer disk drive that needs 6.0 V (rms) instead of the 120 V (rms) from th

Ipatiy [6.2K]

Answer:

$N_{2}$ =20 turns

Explanation:

The given case is a step down transformer as we need to reduce 120 V to 6 V.

number of turns on primary coil N_{P}= 400

current delivered by secondary coil I_{S}= 500 mA

output voltage = 6 V (rms)

we know that

$I_{p}=\frac{V_{out}}{V_{in}\times I_{s}}$

putting values we get

$I_{p}=\frac{6}{120\times 0.5}$

$I_{p}= 0.1 A$

to calculate number of turns in secondary

$\frac{N_{2}}{400} =\frac{6}{120}$

therefore, $N_{2}$ =20 turns

Which of the following statements explains why a race car going around a curve is accelerating, even if the speed is constant? A

Tom [10]

OPTION C The car is accelerating because the direction of velocity is changing explains why a race car going around a curve is accelerating, even if the speed is constant

When a body is in uniform circular motion ( constant speed ), it will continuously cheanges its direction and so the body is accelerating

The rate at which an item changes its velocity is known as acceleration, a vector variable. If an object's velocity is changing, it is accelerating.

As a vector quantity, acceleration has a direction attached to it. The acceleration vector's direction is determined by two factors: if the thing is slowing down or speeding up the direction the thing is travelling in (+ or -)

The following general rule is used to calculate acceleration:

An object's acceleration will be in the opposite direction of its velocity if it is slowing down.

You may use this basic concept to determine if an object's acceleration is positive or negative, to the right or left, up or down, etc.

Which of the following is a small electronic component made up of transistors (tiny switches) and other miniaturized parts?

Vlad [161]

Answer:

Integrated circuit (IC)

Explanation:

An integrated circuit ( IC ) is a semiconductor which contains multiple electronic components

interconnected to form a complete electronic function. Integrated circuits are the most essential part of all electronic products.

Modern integrated circuits contain as much as billions of circuit components such as transistors , diodes , resistors , and capacitors

onto a single monolithic die .

Hydrogen cyanide (HCN) is a product of combustion that:

bekas [8.4K]

b. is equally as toxic as carbon monoxide (CO).

Explanation:

Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.

The gas is a product of combustion in blast furnances, coke ovens, e.t.c

Just like carbon monoxide, they are blood agents that are toxic in the body
Prolonged exposure to hydrogen cyanide can lead to death eventually.
The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
It is listed as one of the dangerous chemical weapons.
