The Beams And Joints That Hold It .
Answer:
The induced emf between two end is 
V
Explanation:
Given:
Length of rod 
m
Height 
m
Magnetic field 
T
For finding induced emf,
Where 
velocity of rod,
For finding the velocity of rod.
From kinematics equation,
Where 
initial velocity, 
Put the velocity in above equation,
V
Therefore, the induced emf between two end is V
Answer:
When the source of pollution is widely distributive in nature, it is called as the Non-point source pollution, for example, <em>acid rain</em>.
Explanation:
the source of pollution when is <em>not concentrated over a particular area</em> or any particular defined pinpoint is termed to be as the Non - point source pollution.
this type of pollution is very hard to be monitored or controlled due to its nature of widely distributive nature of the origin. It has <em>several pathways</em> for the effect to undertake and thus the control over the effect is <em>not easily accessible. </em>
For example, during rain, the tree fall off can enter water stream from any source, either be it open lake or ponds or even street fall offs.
