the reason why sound travels faster in solid is because the molecules in solid is more close to each other and they allow the waves of the sound to travel quickly or easily. and same reason why the sound travels fast in liquid that gas, it's because the molecules in liquid is closer to each other than the molecules in gas but they're not as close as solid hence why solid is the fastest at traveling sound
Yes. The noble gases are just a specific type of non metals. Such as the halogens.
Given:
altitude, x = 1 mile
speed, v = 560 mi/h
distance from the station, x = 4 mi
Solution:
To find the rate,
Now, from the right angle triangle in fig 1.
Applying pythagoras theorem:
differentiating the above eqn w.r.t 't' :
(1)
Now, putting values in eqn (1):
The rate at which distance from plane to station is increasing is:
Answer:
<u><em>370.114 meters.</em></u>
Explanation:
Hope this helped! :)
The object is in free fall when and only when it is being affected by gravity alone. It is not being influenced by a significant amount of air resistance will always be in free fall. F(net)/m = acceleration
