We use the formula,
Here, h is the variable represents the height of the flare in feet when it returns to the sea so, h = 0 and u is the initial velocity of the flare, in feet per second and its value of 192 ft/sec.
Substituting these values in above equation, we get
.
Here, t= 0 neglect because it is the time when the flare is launched.
Thus, flare return to the sea in 12 s.
Answer: D.) 3hrs
Explanation:
Given the following :
A boat can move at a constant velocity of 8 km/h; How long will it take for the boat to move 24 km
Recall:
Velocity = Displacement / time
For the boat to travel a distance of 24 km at a constant velocity of 8km /hr
Time taken = Displacement(distance moved) / velocity
Time taken = 24km / 8kmhr^-1
Tine taken = 3hrs
The key thing we look for is <u>WATER.</u> We need to analyze whether a world is a possible home to life if it has the past, present, and future existence of liquid water.
Even if the planet has evidence of atmospheric oxygen, it is still insufficient for humans to live in it if it lacks H2O.
Some may argue that the presence of organic molecules such as amino acids should also be taken into account. Even if they have a valid point, it is not the most significant factor that we consider when deciding if the world is a possible home for life.
Aside from water, the world's surface color changes that indicate vegetative growth can be critical in ensuring that the world is habitable. However, vegetative growth is insufficient to be significant if the planet lacks a consistent source of water.
The first confirmed Earth-size planet where liquid water might accumulate on the surface is Kepler-186f. The discovery of another world provides evidence that there are planets in other stars' habitable zones.

Answer: Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
Explanation:I search it up °-°
That graph is called a Line plot
