**Answer:**

**Explanation:**

As we know that the level of intensity is given as

here we know

now the sound is travelling in all possible directions so we have

now for level of sound we have

<h3>What is Physics?</h3>

Física es un término que proviene del griego physis y que significa “realidad” o “naturaleza” y por eso también podemos definirla como la ciencia que estudia las propiedades del espacio, el tiempo, la materia, la energía y sus interacciones.

<h3>What is the amount?</h3>

It is a measurable property that admits degrees of comparison and represents either a count of the number of elements in a set, or the result of a physical measurement of a magnitude.

**Explanation:**

It is given that,

Mass,

Center of gravity,

Mass,

Center of gravity,

Mass,

Center of gravity,

Let the 6 kg object of mass is placed at point (x,y). The center of gravity is calculated as :

**x = -0.933 meters**

For finding y,

**y = -3.2 meters**

**So, the center of gravity of the four-object arrangement will be at (-0.933,-3.2). Hence, this is the required solution.**

Answer:

c. "Ohmic" is when the plot of I [Amp] versus V [Volt] has a slope equal to R.

Explanation:

A resistor is said to be Ohmic if it obeys ohms law. In am Ohmic resistor, the resistance is constant regardless of the current passing through it. Graphically, an ohmic resistor as a linear relationship when its current and voltage relationship is presented graphically.
