The loudness of the sound at the rock concert, where the intensity of the sound is1 x 10⁻¹ Wm⁻² is  110 dB.
Here we are dealing with loudness which is the perception of the Intensity of the sound.
The formula  to refer to in order  to  find the value of the loudness of a sound is ,
    db= 10log(I/I₀)
As we are provided with the current intensity which is  1 x 10⁻¹ Wm⁻². and the initial intensity which is  1 x 10⁻¹² Wm⁻².
 So, by substituting the required values in the formula we get 
 db= 10 * log( 1 x 10⁻¹ /1 x 10⁻¹²)
  = 10 * 11 log(10)
  = 110
So, the result is 110 dB.

Answer:
1185 N
Explanation:
From Newton’s second law of motion,  
F=ma where m= mass of motorcycle, a is acceleration of the motorcycle and F=Force
Net force acting on motorcycle  is given by
 is given by   
Where F is force acting on motorcycle and f is frictional force
Substituting F-f for  
 hence  ma= F- f Substituting a with 3, m with 245Kg and f with 450N as provided
 hence  ma= F- f Substituting a with 3, m with 245Kg and f with 450N as provided
245*3= F- 450
F=245*3 +450= 1185 N
