A. They change the motion of objects
Answer:
380m
Explanation:
We have the speed of the spaceship v = 0.75c
Max measures contracted length L of the spaceship as it travels
We have been given L = 250m
As this ship stops he is going to get exact length of the ship = Lol
We solve using this formula
L = Lo√ 1-v²/c²
From the formula above we make Lo subject of the formula
When we input values
Lo = 250/√1-(0.75c/c)²
= 250/√1-(0.75)²
= 250/√0.4375
= 250/0.6614
= 377.98
This is approximately 380
Answer:
B. Check her building’s foundation to ensure it is resistant to shaking caused by moving tectonic plates
Explanation:
The phase of matter has a large impact upon the elastic properties of a medium. In general, the bond strength between particles is strongest in solid materials and is weakest in the gaseous states As a result, sound waves travel faster in solids than in liquids, and faster in liquids than in gasses.
