Products and reactants contain the same atoms, but the atoms are in different combinations. Since the atoms are moved to other places in the reaction, a new chemical product is generally produced.
Answer:
S = 122.5m
Explanation:
Given the following data;
Acceleration due to gravity = 9.8m/s²
Time, t = 5 seconds
Since it's a free fall, initial velocity, u = 0
To find the displacement, we would use the second equation of motion given by the formula;
![S = ut + \frac {1}{2}at^{2}](https://tex.z-dn.net/?f=%20S%20%3D%20ut%20%2B%20%5Cfrac%20%7B1%7D%7B2%7Dat%5E%7B2%7D)
Where;
- S represents the displacement or height measured in meters.
- u represents the initial velocity measured in meters per seconds.
- t represents the time measured in seconds.
- a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
![S = 0*5 + \frac {1}{2}*(9.8)*5^{2}](https://tex.z-dn.net/?f=%20S%20%3D%200%2A5%20%2B%20%5Cfrac%20%7B1%7D%7B2%7D%2A%289.8%29%2A5%5E%7B2%7D)
S = 122.5m.
Lúc 6 giờ sáng một học sinh đi học từ nhà đến trường mất 10 phút quãng đường từ nhà đến trường là 6 km hỏi học sinh đi với vận tốc là bao nhiêu
Answer:
A reference point is a place or object used for comparison to determine if something is in motion
An example of a reference point that is moving is when you look out the window of a car and notice that you are moving faster than the car next to you
