Answer:0.077
Explanation:
Given
banked designed for traffic moving at 
Radius of the curve 201 m
Actual traffic velocity =
For banking of road
Centripetal acceleration is given by
Taking component of centripetal acceleration
along and perpendicular to surface
From FBD
----1
where 
is frictional force
----2
and we know coefficient of friction is given by
Virtual upright and the same size
Yes because there is more echo and a larger volume for the sound waves to travel
We know, U = F * h
U = 25 * 3
U = 75 J
In short, Your Answer would be 75 Joules
Hope this helps!
Answer: False
Explanation:
That is false. This is implying the existence of magnetic monopoles, which we do not know exist. As far as we know, magnetic monopoles don't exist and its impossible to create one. Due to Maxwell's equations, it implies that a magnetic monopole <em>should</em> exist, but we have not yet found one.
