The intensity of sound is just like the force of gravity, the force between electric charges, and the intensity of light . . . they all DEcrease at the same rate that the SQUARE of the distance INcreases.
So if two people are watching or listening to the same source, and one intensity is 1/10 as intense as the other intensity, then the farther person must be √10 times as far from the source as the nearer person is.
√10 = 3.1622 ...
So the second guy is about <em>3.16 miles</em> from the fire truck.
Answer:
There are five signs of a chemical change:
Color Change.
Production of an odor.
Change of Temperature.
Evolution of a gas (formation of bubbles)
Precipitate (formation of a solid)
Explanation:
I just went ahead and gave you the five signs of chemical change hoped it helped
The electric power (P) produced by an electric current (I) passing through a voltage (V) is given by the equation:

If the battery charger works with a voltage of 12V, replace V = 12V into the equation, as well as the corresponding values for the electric current to find the power produced in each case.
A) I = 10A
Replace V=12V and I=10A to find the power produced in the fast charge mode:

B) Replace V=12V and I=2A to find the power produced in the trickle charge mode:

Therefore, the power produced by a 12V battery charger is equal to 120 Watts when it delivers 10A in fast charge mode, and 24 Watts when it delivers 2A in trickle charge mode.
Answer:
If the force of gravity increases or gravitational force increases the weight of the Object D. Increases.
Fg = W = m•g
Fg = force of gravity
W = weight
m = mass of object
g = acceleration due to gravity.
g
