Answer:

C. R is not equal to -10

Step-by-step explanation:

Restrictions usually deal with preventing the case of dividing by 0. In this case, you'll look at the denominator.

If R = -10 and 10 was added to it, then the denominator would become 0.

Therefore, the expression would be messed up.

Anna71 [15]

Answer:

The right answer is "5.9". A further solving is provided below.

Step-by-step explanation:

The given values are:

Initial Magnitude,

M₁ = 3.9

Let Second magnitude be M₂.

Now,

⇒ $M_2-M_1=log(\frac{l_2}{l_1} )$

On substituting the values, we get

⇒ $M_2-3.9 = log (120)$

On putting the value of "log 120", we get

⇒ $M_2-3.9=2.079$

On adding "3.9" both sides, we get

⇒ $M_2-3.9+3.9=2.079+3.9$

⇒ $M_2=5.9$
