The Winter Olympics are held every 4 years.
A greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.
<h3>What is kinetic energy?</h3>
It should be noted that kinetic energy simply means a form of energy of an object due to motion.
In this case, a greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.

meeeeeeee ty for the points! :D
The problems with orders database are;
- When there is Incomplete or Missing Integrations: In this kind of issues, the consequences is that businesses are said to not perform to their optimum level as they have to workarounds the issue with the systems.
- Erratic or Slow Syncs: This slow rate that has errors can lead to incorrect shipping and inventory data.
- Unresponsive Customer Service: When the issues of customer, yare not addressed on time, customers may be rude to the brand and other issues will arise.
<h3>What are the problems with databases?</h3>
The Database Problems are:
- Slow Read-Write Speeds.
- Scaling Problems.
- Wrong Virtual Machine settings, etc
A database is known to be a form of organized make up of structured information, or data, that are said to be stored electronically in a computer system.

<h3>
Answer:</h3>
60 days
<h3>
Explanation:</h3>
Half-life is the amount of time it takes half of a substance to decay away.
Guess and Check
One method for solving half-life problems like this is to guess and check. To do this, we can continue to divide 475mg by 2 until we get to 30mg.
- 475 ÷ 2 = 237.5
- 237.5 ÷ 2 = 118.75
- 118.75 ÷ 2 = 59.375
- 59.375 ÷ 2 = 29.6875
As seen here, it takes approximately 4 half-lives for this sample of Ra-225 to decay to 30mg. Now, we can multiply 4 by the length of the half-life, 15 days.
Fractions
Another way to solve this is to use fractions.
- 16 is equivalent to
.
This means that it takes 4 half-lives for 475mg to decay to 30mg. Using the same method above, we can tell that 4 half-lives are 60 days.
Important Note
In this question, I rounded occasionally. So, not all of the values are exact, but they are all very close.
