There are four characteristics of a state. population,government,sovereignty,and territory.
Hello!
What Deshawn notices is that the volume of the bubbles increase as they get closer to the surface of the water.
This occurs because of the
Boyle's Law. That Law states that when pressure decreases at constant temperature (like in water), the volume of a gas increases (
).
What is happening is that as the bubbles get closer to the surface of the water, the pressure on them decreases, causing their
volume to increase, and that is seen by the increase in the size of the Bubbles that Deshawn noticed.
Have a nice day!
Strength to weight ratio is better for a hollow pipe than a solid<span> rod." This means a </span>hollow cylinder<span> is </span>stronger than<span> a rod of equal mass and the same material. A </span>hollow cylinder<span> with a bigger inside diameter is better.</span>
This is just testing your ability to recall that kinetic energy is given by:
<span>k.e. = ½mv² </span>
<span>where m is the mass and v is the velocity of the particle. </span>
<span>The frequency of the light is redundant information. </span>
<span>Here, you are given m = 9.1 * 10^-31 kg and v = 7.00 * 10^5 m/s. </span>
<span>Just plug in the values: </span>
<span>k.e. = ½ * 9.1 * 10^-31 * (7.00 * 10^5)² </span>
<span>k.e. = 2.23 * 10^-19 J
so it will be d:2.2*10^-19 J</span>
