Answer: The canyon wall is 850 m away from the person
Explanation:
Well, the speed of sound 
in air at 
is defined as 
, this can be calculated by the following equation:
(1)
Where:
is the Heat capacity ratio for air
is the Universal Gas constant
is the temperature in Kelvin
is the air molar mass
(2)
Now that we know the speed of sound, we can use the following equation to find the distance between the person and the canyon wall:
(3)
Where:
is the distance between the person and the canyon wall
is the time it takes to the sound wave to travel from the person and then go back
Isolating :
(4)
(5)
Finally:
Answer:
a. Magnetic field is a location of a vector field around an electric current or magnet formed due to moving electric charges, or magnetic material and has a magnetic effect and exerts a force on other magnetic materials, electric current, and electric charges. The Earth's magnetic field that has the effect of turning a compass needle is an example of a magnetic field
b. The number of turns of the coil, N, in Diagram 1.1 > The number of turns of the coil, N, in Diagram 1.2
The pattern of the iron filings in Diagram 1.1 are closer with less space in between than the pattern of iron filings in Diagram 1.2
The angle of deflection of the ammeter pointer in Diagram 1.1 will be > The angle of deflection of the ammeter pointer in Diagram 1.2, given that the number of turns and current are inversely proportional
c. i. The pattern of the iron filings will have rings which are more closely arranged to each other as the strength of the magnetic field is increased
ii. As the number of turns is increased, the magnetic field is increased
