A spring stretches 0.2 cm per newton of applied force. An object is suspended from the spring and a deflection of 3 cm is observ
siniylev [52]

Answer:

m=1.53kg    

Explanation:

To solve this problem we use the Hooke's Law:

F=k*\Delta x     (1)

F is the Force needed to expand or compress the spring by a distance Δx.

The spring stretches 0.2cm per Newton, in other words:

1N=k*0.2cm ⇒ k=1N/0.2cm=5N/cm  

The force applied is due to the weight

F=mg

We replace in (1):

mg=k*\Delta x  

We solve the equation for m:

m=k*\Delta x/g=5*3/9.81=1.53kg

Two capacitors are connected in series and the combination is charged to 120V. There's 90.0V across one capacitor, whose capacit
IgorC [24]

Answer:

0.84μF

Explanation:

Charge is same through both the capacitors since they are in series. Total voltage is the sum of the voltages of the individual capacitors.. So voltage across the 2nd capacitor is 120- 90 =30 V.

Charge across first capacitor is Q = C₁V₁ = 90 x0.28 = 25.2μC

Therefore capacitance of 2nd capacitor =

C₂ = Q÷V₂ = 25.2÷30 = 0.84 μF

AfilCa [17]

If someone said that instruments that produce sounds by vibrating themselves are called aerophones. <u>False</u>

<h3>What is aerophones?</h3>

An aerophone is a musical instrument that makes sound primarily by forcing a body of air to vibrate without the use of strings or membranes, and without the vibration of the instrument itself significantly enhancing the sound.

<h3>What is aerophone instrument?</h3>

Any of a group of musical instruments known as aerophones, in which the initial sound is produced by a mass of vibrating air. Instruments that don't fit into any of these categories, such the bull-roarer and the siren, are also included in the basic types, along with woodwind, brass, and free-reed instruments.

<h3>What are African aerophones?</h3>

Aerophones, which create music by vibrating columns of air, are among the instruments used in Africa. Flutes, reed pipes, and trumpets and horns are the three major types of African aerophones.
