What gas? Gas is an invisible form so I don't see how it would have a "defined structure".
It’s the engery. you are changing the engery
Answer:
7,79 seconds
Explanation:
You need to use the acceleration formula. A is acceliration, 
is change in velocity and t is time.
You need to multiply the formula with t and divide by a and you get
a*t=
t= /a
after that you just need to insert the numbers
change in velocity is 76.4 minus 0.
acceliration is gravitational acceleration which is 9.81.
After that you get
t=76.4/9.81
t= 7,787971458 s
<span>Wind is nature's way of balancing the temperature between hot and cold. Wind always flows from heat to cool. When night falls, the air cools. And since it gets cooler at night it reverses.</span>
A concave mirror is curved inward in the middle, more
like a cave. Because the mirror is curved inward, the angle of the light
surface can be focused similar to that of the camera. They can form real images
that are projected out in front of the mirror at the place where light focuses.
When the object is located at the center of the curvature the image formed will
also be at the curvature. The image will be inverted and the magnification
value is equal to 1 which will become a real image because the ray of light
converges at the location of the formed image.
