The wave will decrease in its frequency due to a disturbing force acting upon it.
Answer:half of shorter Pipe
Explanation:
Fluid is Flowing through two horizontal pipes with pressure difference

Both pipes have same radius
Length of one Pipe is twice of other
Let Longer Pipe be denote by 1 and smaller by 2
From Hagen Poiseuille equation

Where
viscosity of medium
L=length of Pipe
Q=discharge
D=diameter
For longer Pipe
----1
For smaller Pipe
------2
From 1 & 2 we get


volume flow rate of longer pipe is half of smaller pipe
Answer:
10000 Bq / 625 Pq = 16
Radioactivity has decreased by a factor of 16
2^4 = 16
So the sample has gone thru 4 half-lives
24 da / 4 = 6 da
6 da is the half-life
Answer:
UV light
climate
hydrofluorocarbons or HFCs
pollutants
heat
As sunlight falls on Earth's surface, it heats up the surface. Infrared light is emitted from the surface and is absorbed in the atmosphere, where it is converted to heat. This heat remains trapped in the atmosphere, causing the temperature near the surface to increase.
Explanation:
these are all correct
