Answer:
The angular speed of the reel is 11.33 rad/s
Explanation:
Given
The fisherman takes t = 8.4 s to wind distance x = 2.9 m into a circle radius of r = 3 cm = 0.03 m
Than the tangencial speed equals the change in the distance to the time
v = 
= 
Knowing the tangencial velocity is proportional to the radius r and the angular velocity
v = r*w
w = 
a tendency of a body to do nothing or to remain unchanged.

Explanation:
Water has the high specific heat capacity.
That means it resists to change its temperature when a considerable amount of heat lost or gained
4200J is needed to raise the temperature of 1kg substance by 1 degree Celsius
