There are several instruments used to measure loudness. Loudness's unit is "decibel". You can use a microphone and a software to measure loudness. For windows : Free Decibel Reader or Audacity.

I think the correct question would be, how do you measure sound. :)
you measure sound by using amplitude. It measures how forceful the sound is.
Thats how you know whether its loud or quite :)

A long wire carries a current 5 A from west to east. A magnetic compass pointing North is placed underneath the wire at a distan

Gemiola [76]

Answer:

no deflection

Explanation:

current is flowing from west to east. As the magnetic field of a long wire carrying current is circular, its direction will be north below the wire and south above the wire (according to the right hand rule). So, when the compass is placed underneath the wire, it will still point towards the north direction.

What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2

Basile [38]

Answer:

$\boxed {\boxed {\sf 252.5 \ Newtons }}$

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

$F=m*a$

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

$m= 50.5 \ kg$

$a= 5.0 \ m/s^2$

Substitute the values into the formula.

$F= 50.5 \ kg * 5.0 \ m/s^2$

Multiply.

$F=252.5 \ kg*m/s^2$

1 kilogram meter per square second is equal to 1 Newton.
Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.

$F= 252.5 \ N$

The force required is <u>252.5 Newtons</u>.

An emf source with emf of 200 V, a resistor with R =50.0 Ω, and a capacitor with C = 4.0 mF are connected in series. As the capa

Gemiola [76]

Answer:

0.6 C

Explanation:

From the question,

Since the Resistor and the capacitor are connected in series.

The voltage across the resistor + Voltage across the capacitor = Total voltage.

Vt = Vr+Vc............... Equation 1

Where Vt = Total voltage, Vr = Voltage across the resistor, Vc = Voltage across the capacitor

make Vc the subject of the equation

Vc = Vt-Vr.............. Equation 2

From ohm's law,

Vr = IR................... equation 3

Where I = current, R = Resistance.

Given: I = 1 A, R = 50 Ω

Substitute into equation 3

Vr = 1(50)

Vr = 50 V

Also given: Vt = 200 V

Substitute into equation 2

Vc = 200-50

Vc = 150 V.

Applying,

Q = CVc..................... Equation 4

Where Q = charge on each plate of the capacitor, C = Capacitance of the capacitor

Given: C = 4.0 mF = 4.0×10⁻³ F, Vc = 150 V

Substitute into equation 4

Q = 4.0×10⁻³(150)

Q = 0.6 C
