Answer:

 oil floats in water due to the fact that it is less dense. since the water is more dense, it is basically heavier, and heavier items always sink, while lighter items float, the same can be said about liquids. denser liquids will sink while less dense items will float.

Which resultant force is NOT possible if 50 N force and a 60 N force act concurrently?
Sergio [31]

Answer:

The options are not shown, so i will answer in a general way.

Suppose the case where the forces act in opposite directions, then we need to subtract the forces, and we know that the magnitude of the resultant force will be:

60N - 50N = 10N

Now, suppose the case where both forces act in the exact same direction, in that case, we will add the forces to get:

60N + 50N = 110N

Then the only range of forces that we can get in this system, are the forces such:

10N ≤ F ≤ 110N

Any resultant force outside that range is not possible in this situation.

The __________________________________ of a sound is related to the amount of energy flowing in the sound waves.
pashok25 [27]

Answer:

intensity

Explanation:

The intensity of sound is a measure of how much <em>energy is flowing (through a unit area in which is perpendicular to the direction of the sound) per unit time.</em>

Its unit are micro joules per second per square cm. or watt per square cm.

watt is the unit of power and is gotten by the fact that power is the rate of doing work. so, p=E/t . The italicized text above (energy per unit time) can be replaced by power,p.
