Explanation:
In order for the wood to sink, it's specific gravity must equal 1 (or greater).
Specific gravity = .6 kg/m^3= Mass/volume
F (Newtons or kg x m/s^2) = Mass*9.8m/s^2.
Therefore, Mass = 160 N / 9.8 m/s^2= 16.32 kg
Volume = Mass/Specific Gravity = 16.32kg/.6 kg/m^3 = 27.2 m^3
Desired Specific gravity = 1 = (Mass + additional force/9.8m/s^2)/Volume = (16.32 kg +X / 9.8m/s^2)/27.2m^3
Solving for the additional force: X = 106.66...N
The answer is D, 110 N will be required to sink the block of wood.
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. ... As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.

The answer would be stage of<span> conversion of Hydrogen to Helium.
At the end of this phase, the helium content of the suns will have the popping effect where more and more helium is now on the core resulting to higher temp and density as helium converted from hydrogen is much heavier.</span>
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Give the relation of resistance of wire with the length and thickness:
Resistance:
There is a resistance to the flow of an electric current through most conductors.
The length of wire increases
The thickness of wire decreases
The resistance of a long wire is greater then the resistance of a short wire because electrons collide with more ions as they pass through.
The relationship between resistance and wire length is proportional. The resistance of thin wire is greater then the resistance of a thick wire because a thin wire has fewer electrons to carry the current.The relationship between resistance and the area of the cross section of wire is inversely proportional.
