What is the velocity of a dog who travels south 50 meters in 9 seconds
julia-pushkina [17]
Roughly 5.6 meters per second (m/s)

Velocity is determined by distance divided by time. In this case, we divide 50 meters by 9 seconds, giving us the dog’s velocity of 5.55555 (repeating) meters per second. We can round to 5.6 m/s if needed.

Explain what causes acid rain to form and its negative effects on living and nonliving things.
OLga [1]
What causes it to form: <span>Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Human activities, power plants, and exhaust from vehicles all are causes.</span>
Affects on living things-
Acid rain can kill trees
It can affect plant growth patterns
Toxins can kill animals
Nonliving things- 
It can decay building materials and paints
it breaks down rocks

Vika [28.1K]

Answer:

<h2> 27m/s</h2>

Explanation:

Given data

initital velocity u=15m/s

deceleration a=3m/s^2

time t= 4 seconds

final velocity v= ?

Applying the expression

v=u+at------1

substituting our data into the expression we have

v=15+3*4

v=15+12

v=27m/s

The velocity after 4 seconds is 27m/s
