Answer: D. plant more trees where forests are cut down.
Explanation:
Deforestation has to do with the cutting down of trees. Cutting down the forest reduces the size of animal habitats, increases erosion, and results in an increase in the amount of carbon dioxide in the atmosphere.
Ok order to tackle the above, it is necessary that we should plant more trees where forests are cut down.
The total distance travelled is 307.5 miles.
<h3>What is the distance covered?</h3>
We know that the distance covered can be obtained from the formula from speed since the motion all took place in the same direction.
Speed = distance/time
distance = speed * time
In the first case;
Distance = 35 mph * 2.5 hours = 87.5 miles
In the second case;
Distance = 55 mph * 4.0 hours = 220 miles
Total distance = 87.5 miles + 220 miles = 307.5 miles
Hence the total distance travelled is 307.5 miles.

Answer:
Explanation:
The equation for this is
f = μ
where f is the frictional force the block needs to overcome, μ is the coefficient of static friction, and 
(that means that the normal force is the same as the weight of the block which has an equation of weight = mass times the pull of gravity). Filling in:
1.09 = μ(.413)(9.8) and
μ = 
so
μ = .27
Answer:
v = 8.8 m /s
Explanation:
For listener and source going away from each other the formula of Doppler effect is as follows
V is velocity of sound , v is velocity of listner and source of sound
f₀ is apparent frequency and f is real frequency
V = 343 , v = ? ,f = 210 , f₀ = 221
Put these value in the relation above
![[tex]\frac{210}{221} = \frac{343-v}{343+v}](https://tex.z-dn.net/?f=%5Btex%5D%5Cfrac%7B210%7D%7B221%7D%20%3D%20%5Cfrac%7B343-v%7D%7B343%2Bv%7D)
[/tex]
v = 8.8 m /s
It’s important because if you were let’s say training to see how far you go in 10sec you need to record your data to see how much you are improving in that skill or something
