Fnet = Fg sin 30 - Ff
ma = mg sin 30 - mew Fg cos 30
ma = mg sin 30 - mew mg cos 30
a = g sin 30 - mew gcos30
a - g sin 30 = - mew g cos 30
mew = -(a - g sin30)/(g cos 30)
mew = -(3m/s2 - 9.81sin30)/(9.81 cos 30)
mew = 0.22
First off, Newtons dont measure weight, it measures force. Assuming thats a tyo, the answer is 20 N
The magnitude of the force exerted by the fish is 3,052.5 N.
The given parameters;
- mass of the reel, m = 652 g = 0.652 kg
- diameter of the reel, d = 10 cm
- radius of the reel, r= 5 cm = 0.05 m
- angular speed of the reel, ω = 306 rad/s
According to Newton's third law, the force exerted by the reel is equal in magnitude to the force fish exerted on the reel.
The centripetal force of the reel = force exerted by the fish
Thus, the magnitude of the force exerted by the fish is 3,052.5 N.

Intensity:
Decibels
Amplitude:
Meters
Frequency: Hertz
<u>Explanation:</u>
The Wave is not visible to eyes and they can easily propagate through vacuum. the average power travelling at a given period of time in a space is the intensity. Decibels is the measure of intensity. it is measured in the decibel scale. The wave's strength and the intensity gives the amplitude of wave. It is measured using meters.
The wave's amplitude and the energy has a direct proportionality. The number occurrence of wave cycles per second refers to the frequency of wave. it is measured in hertz. it is also measured as the number of cycles that occurs per second.
