Answer: i dont know what is happening but I'm answering with another HEEEYYYYYYY HEYYYYYYYY
Explanation:
The water exerts a net drag force on the boat, and tends to make the boat move along with the average water flow, or stay put if the water isn't going anywhere. The water will heat up slightly as energy from the big motion ...
electric potential energy..electrons get the the kinetic energy from the voltage applied across the conductor
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).

Answer:
E = 31.329 N/C.
Explanation:
The differential electric field
at the center of curvature of the arc is
<em>(we have a cosine because vertical components cancel, leaving only horizontal cosine components of E. )</em>
where
is the radius of curvature.
Now
,
where
is the charge per unit length, and it has the value

Thus, the electric field at the center of the curvature of the arc is:


Now, we find
and
. To do this we ask ourselves what fraction is the arc length 3.0 of the circumference of the circle:

and this is
radians.
Therefore,

evaluating the integral, and putting in the numerical values we get:
