Explanation:
As we know that radius of the brass ring is given as

radius of the sphere is given as

now by thermal expansion formula we know that

so we will have

so we have

Answer:
Petametres; 41 Pm
Explanation:
A measurement should use units that give a number between 0.1 and 1000.
The measure that astronomers use is the light year — the distance that light travels in one year.
In those units, the distance is 4.3 light years.
We can calculate the distance in SI units.

In SI, we should measure the distance in petametres (1 Pm = 10¹⁵ m)
Thus, the distance to the nearest star is 41 Pm.
Given what we know about driver and road safety precautions, we can confirm that the statement " tires should always be filled to the maximum pressure indicated on the side of the tire" is false.
<h3>Why should tires not be filled to the maximum air pressure?</h3>
- Tires should never be filled to the maximum air pressure.
- This would cause the tire to have no room for shifts.
- Under normal conditions in the case of a popped tire, the tire will gradually lose air, needing to be inflated.
- <u>This presents no danger to the driver if identified on time.</u>
- Under conditions of increased pressure, the tire can explode instead of losing air gradually.
- This causes the loss of control of the vehicle and danger to the driver and others.
Therefore, we can confirm that the statement " tires should always be filled to the maximum pressure indicated on the side of the tire" is false given that filling the tires to the max allowed pressure greatly increases the odds of the tire exploding and causing the driver to lose control of the car.

Answer: if a ice cube melts its a liquid but when water's being evaporated it turns into a gas like when you boil water and they also work together because let's say your outside and you see a puddle which is a liquid but the next time you go and see it you notice that the puddle is gone this means the puddle puddle has evaporated and turned into a cloud.
