Answer:
to help people breach in fresh air
Explanation:
The Milky Way galaxy ...
-- Is farthest from the sun.
No. The sun (and the whole solar system, including US)
is IN the Milky Way galaxy.
-- Has the most stars.
No. It's a pretty big galaxy, but we can see others that are bigger.
-- Has the biggest stars.
No. Every galaxy has the whole spread of sizes,
from dwarf stars top super giants.
-- Contains our solar system.
Yes ! That's it. We live in the Milky Way galaxy.
...because velocity is a vector quantity, which means that it includes both the magnitude and the direction of motion.
The speedometer only measures the speed of the car and not its velocity. Speed is a scalar quantity, which means that it only indicates magnitude and not direction of the motion. Thus, the speedometer only shows the distance covered by the car with time (speed), but it does not indicate if the car is moving forward, backward, left or right.
The height of the 500-mb pressure level plotted at North Platte (LBF) in western Nebraska was 5,570 meters m above sea level.
<h3>
What is pressure?</h3>
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
<h3>Pressure level plotted at North Platte</h3>
Recalling that the heights plotted at individual stations on 500-mb maps are in tens of meters (place a 0 to the right of the three plotted digits).
The coded height at North Platte, in west-central Nebraska, ("557") indicated 500 mb occurred at 5,570 meters above sea level.
Thus, The height of the 500-mb pressure level plotted at North Platte (LBF) in western Nebraska was 5,570 meters m above sea level.

Answer:
a. 
is the time after which the two stone hit the water surface.
b. 
c. 
& 
Explanation:
Given:
- height of the cliff,
- time gap between the projection of stones,
- initial velocity of first stone,
Here positive sign means that the stone is thrown vertically downward in the direction of gravity.
a.
Using equation of motion:
is the time after which the two stone hit the water surface.
b.
using the equation of motion for second stone:
c.
Final velocity of the stone at the instant of touching the water surface:
&
