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 = 
Light bulbs, think about parallel circuits as something you plug into, so for example you plug in a tv for it to work, same with a refrigerator and Christmas lights

There are not enough electrons in atoms to affect the total mass, so the total mass is just the weight of the protons and neutrons.
This is known to be named supernova it a time in a stars life where it has reached it's final stage. It concludes that when stars explode supernova occurs or an tear in space is created know as a "blackhole". The star can only explode once it has survived over along period of time.
