Answer:
0.032
Step-by-step explanation:
The drag force is described as the force experienced by an object due to movement through a liquid. In this case it is water. The equation used for drag force F is:
![F=0.5pu^2](https://tex.z-dn.net/?f=F%3D0.5pu%5E2)
the density of water is p=1000 kg/m³. We know that F=0.5 N.
![0.5=0.5\cdot{1000}u^2](https://tex.z-dn.net/?f=0.5%3D0.5%5Ccdot%7B1000%7Du%5E2)
![u=\sqrt{0.001}](https://tex.z-dn.net/?f=u%3D%5Csqrt%7B0.001%7D)
![u=0.031](https://tex.z-dn.net/?f=u%3D0.031)
The speed is 0.032 m/s
You know that a 24 degree angle is 75.20 and that 12 is all the angles around it so take that and add 75.20 and the sides?
The answer is option 2, it subtracts by four each time.
