Answer:
Hello friend where is the figure of the question
Radiation is a type of heat transfer wherein there is no need for medium or media through which the heat will flow. Consequently, the radiation waves are able to travel through vacuum. The best observation as evidence to conclude that heat is indeed transferred by radiation is the increase of temperature of the receiving body.

Answer:
5558643.69 N
Explanation:
F = Force
v = Velocity = 31.5 knots
Converting to m/s
![1\ knot=0.514\ m/s](https://tex.z-dn.net/?f=1%5C%20knot%3D0.514%5C%20m%2Fs)
![31.5\ knot=31.5\times 0.514\ m/s=16.191\ m/s](https://tex.z-dn.net/?f=31.5%5C%20knot%3D31.5%5Ctimes%200.514%5C%20m%2Fs%3D16.191%5C%20m%2Fs)
Power is given by
![P=Fv\\\Rightarrow F=\frac{P}{v}\\\Rightarrow F=\frac{90\times 10^6}{16.191}\\\Rightarrow F=5558643.69\ N](https://tex.z-dn.net/?f=P%3DFv%5C%5C%5CRightarrow%20F%3D%5Cfrac%7BP%7D%7Bv%7D%5C%5C%5CRightarrow%20F%3D%5Cfrac%7B90%5Ctimes%2010%5E6%7D%7B16.191%7D%5C%5C%5CRightarrow%20F%3D5558643.69%5C%20N)
