The answer would be D , the rest are ways humans basically destroy nature
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
Answer:
19.4 seconds
Explanation:
We have:
m: mass of the car = 1500 kg
v₀: is the initial speed = 19 m/s
: is the final speed = 0 (it stops)
: is the coefficient of kinetic friction = 0.100
First, we need to find the acceleration by using the second Newton's law:


Solving for a:

Now we can find the time until it stops:

Solving for t:

Therefore, the time until it stops is 19.4 seconds.
I hope it helps you!
There are several approaches. The most favourable one (in my opinion) is this one:
1. Asking a question
2. Doing a research (how to answer this question)
3. Creating a hypothesis (NOT a thesis!)
4. Experimenting (to prove the hypothesis)
5. Analysing results from the experiment
6. Writing a thesis
